See and Eat! The impact of repeated exposure to vegetable ebooks on young children's vegetable acceptance

Vegetable consumption in young children in the UK is well below the recommended five child-sized portions per day. Effective and practical strategies are therefore needed to encourage vegetable consumption in young children. In this exploratory study, we examine the effects of visual familiarization to foods via See & Eat ebooks, which show vegetables on their journey from ‘field to fork’. As part of a larger study, in which 242 British families completed a range of measures about their family's eating habits, child's food preferences and potential parent and child predictors of these (Masento et al., 2022), parents were invited to download a See & Eat ebook about a vegetable their child did not eat. Thirty-six families participated in the intervention, looking at the ebook with their child for two weeks and reporting on their child's willingness to taste, intake and liking of the vegetable targeted by the ebook and a matched control vegetable before and after the intervention period. Results showed significant increases in parental ratings of children's acceptance of the target vegetable. Willingness to taste and intake ratings improved for the target vegetable, but not the control vegetable, while liking was reported to increase for both vegetables. These results corroborate previous research demonstrating the benefits of familiarising children with vegetables before they are offered at mealtimes and suggest that ebooks can be added to the set of tools parents can use to support children's vegetable consumption.

Understanding the phenomenon of childlessness in Japan: Causes and potential solutions

This abstract explores childlessness in Japan, analyzing its emergence and proposing solutions. Japan’s declining birth rate and increasing number of childless couples pose significant demographic challenges, necessitating an investigation into the factors driving this trend. Examine demographic and socioeconomic influences and delve into the impact of rising living costs, job insecurity, and work-life balance on potential parents’ decisions. Additionally, cultural norms that uphold traditional gender roles and family expectations are scrutinized for their effect on parenthood choices. Transitioning to potential solutions, this essay discusses family-friendly policies, including affordable childcare and parental leave benefits, as measures to alleviate the financial and time constraints couples contemplating parenthood face. Moreover, this essay emphasizes the importance of challenging cultural attitudes surrounding marriage and child-rearing to create a more inclusive and supportive environment. This abstract contributes to understanding the complexity of childlessness in Japan. Identifying key factors and presenting actionable ideas aims to inspire further dialogue and collaborative efforts to address this demographic challenge and foster a sustainable future.

Performance of potential parents for a rainfed tropical wheat breeding program

Performance of potential parents for a rainfed tropical wheat breeding program

Sastav mikronutrijenata proizvoda mlevenja tradicionalnih sorti pšenice poreklom iz Srbije

The deficiency of micronutrients in the human diet is widely recognised as a global problem. The objective of this study was to assess the content of two essential minerals, iron and zinc, in milling streams of old heritage wheat cultivars that have not been produced for more than a half-century to discover potential parent lines with high mineral content for breeding. Kernel size of seven Serbian old wheat cultivars was evaluated for ash content, thousand-grain weight and share of specific kernel fractions. Three cultivars, Crnozrna, Rumska Crvenka and Stara Banatka, were selected as the most appropriate for milling and further analysis of mineral content in the milling streams. The cultivars were milled in a laboratory mill to obtain six flour and two by-product streams. At the same time, iron and zinc content was determined on a graphite furnace atomic absorption spectrometer. After mixing all six flour streams obtained from each cultivar, three different flour types were obtained. The flour with the highest ash content was the "1100" type originating from cultivar Stara Banatka, characterized by the highest iron and zinc content (54.9 mg/kg d. b. and 5.407 mg/kg d. b., respectively). It was estimated that consumption of a daily average bread portion (166 g according to national statistical data) made from Stara Banatka flour could provide about 90% of the recommended daily intake for iron. Therefore, Stara Banatka may be a target cultivar for wheat breeders searching for high-iron parent wheat lines.

Features of the institutional approach to analysis of the pronatalist policy

The paper considers the possibility of applying institutional approach to analysis of the pronatalist policy. The pronatalist policy creates space for institutions that should contribute to achievement of its goals, namely, raising the birth rate. However, the consistent application of the institutional approach has shown the absence of institutions with necessary for these goal parameters such as addressee, regulation, object, conditions and sanctions. Institutional impact should be focused on a target group of people and its characteristics. Depending on the groups' age, it should ensure a new parental status for young people aged 20 to 35 or birth of children in a certain order. Given this evidence for focusing on specific recipients and digitizing this process, an examination of their impact upon the effectiveness of pronatalist policy measures seems warranted. Considering the real, rather than conditional generation, we analyses the dynamics of the number of women and the age-specific fertility rates among women aged 20 to 34. It allows assessing the potential for growth in the birth rate in this real generation and predicting the required level of age-specific fertility rates in the next time period. The paper proposes a model for analysis of statistical data, which requires further verification on a larger array. The author also makes an attempt to model a new institution within the pronatalist policy — the institution of potential parents. As possible sanctions for violation of institutional norms by potential parents, it is proposed to use the mechanism of lost profits, that is, a reduction in additional payments and privileges from the state with an increase in the protogenetic interval.

If You Must Give Them a Gift, Then Give Them the Gift of Nonexistence.

I present a qualified new defense of antinatalism. It is intended to empower potential parents who worry about their possible children's life quality in a world threatened by environmental degradation, climate change, and the like. The main elements of the defense are an understanding of antinatalism's historical nature and contemporary varieties, a positional theory of value based on Epicurean hedonism and Schopenhauerian pessimism, and a sensitive guide for reproductive decision-making in the light of different views on life's value and risk-taking. My conclusion, main message, to the concerned would-be parents is threefold. If they believe that life's ordinary frustrations can make it not worth living, they should not have children. If they believe that a noticeably low life quality makes it not worth living and that such life quality can be reasonably expected, they should not have children, either. If they believe that a noticeably low life quality is not reasonably to be expected or that the risk is worth taking, they can, in the light of their own values and beliefs, have children. The conclusion is supported by a combination of the extant arguments for reproductive abstinence, namely the arguments from consent, moral asymmetry, life quality, and risk.

Polygynandry and high genetic diversity supported by kinship and population genetics from neotropical catfish ichthyoplankton

AbstractKnowledge about reproductive biology is critical for understanding species ecology and evolution, hence their conservation. However, such information remains elusive for many species due to the difficulty of observing mating in nature. Herein, we coupled population and sociogenetic analysis to assess the reproductive biology of an important South American catfish, the “painted catfish” Pimelodus maculatus. We analysed the genetic diversity and kinship patterns of three wild ichthyoplankton samples identified by DNA barcoding and screened with microsatellite loci. We found the same trend in the three samples analysed: a high number unrelated larvae (r < 0.25) and potential parents involved (Ca1, 24♀:24♂; Ca2, 21♀:23♂; Cin, 24♀:25♂), as well as a high number of familial clusters (ML: 19‐21; MCMC: 23‐26). The data indicate a parental sexual proportion close to 1:1 and a polygynandrous mating system. We found high levels of genetic diversity, low GST values (GST < 0.014), but moderate DEST values between the tributary and reservoir samples (DEST > 0.25; Cin x Ca1 or Cin x Ca2), a similar pattern to the observed in adult populations. These results indicate that the mating system of P. maculatus has played an important role in minimising the loss of genetic diversity, a condition that may have favoured the species in a highly fragmented landscape.

Genetic analysis of genome sequence characteristics of two lumpy skin disease viruses isolated from China

BackgroundLumpy skin disease (LSD) is an acute or subacute infectious disease caused by lumpy skin disease virus (LSDV) of genus Capripoxvirus. The outbreaks of LSD were confirmed in the Yili area of the Xinjiang autonomous region in August 2019 and the Fujian province in June 2020. We detected LSDV in our daily monitoring work, then isolated, identified and sequenced the virus, and analyzed the whole genome characteristics of the isolated strain.ResultsWhole genome sequencing revealed that the strains isolated were all LSDV and were named as LSDV XJ201901 and LSDV FJ2019. The results showed that the identity based on whole genome sequences between LSDV XJ201901 and LSDV FJ2019 was 100% and the identity based on whole genome sequences between the two isolated strains and the global LSDV strains was 97.28%-99.99%, with the strain LSDV72/PrachuapKhiriKhan/Thailand/2021 (99.99%) having the highest sequence identity. Analysis of potential recombination events revealed that a total of 18 potential recombination events were identified in strains LSDV XJ201901 and LSDV FJ2019. The two strains are a recombination of Neethling vaccine LW 1959 (GeneBank: AF409138.1) with KSGP 0240 (GeneBank: KX683219.1). It was observed that Neethling vaccine LW 1959 (11/18) and KSGP 0240 (10/18) are involved in most of the potential recombination events.ConclusionsThe virus isolate in this study was LSDV and was identified as a vaccine recombinant strain. The most likely potential parent strains of the two strains in this study are Neethling vaccine LW 1959 and KSGP 0240. The strains in this study are very similar to those isolated in East and Southeast Asia since 2019.

Kinship and genetic variation in aquarium-spawned Acropora hyacinthus corals

Recent scientific advances in ex situ system design and operation make it possible to complete gametogenic cycles of broadcast spawning corals. Breeding corals in aquaria is a critical advance for population management, particularly genetic rescue and assisted gene flow efforts. Genetic rescue projects for corals are already underway to bring threatened species into ex situ culture and propagation, thereby preserving standing genetic variation. However, while breeding corals is increasingly feasible, the consequences of the aquarium environment on the genetic and phenotypic composition of coral populations is not yet known. The aquarium environment may in itself be a selective pressures on corals, but it also presents relaxed selective pressures in other respects. In 2019 and 2020, gravid Acropora hyacinthus coral colonies were collected from Palauan reefs and shipped to the California Academy of Sciences (CAS) in San Francisco. In both years, gametes were batch-fertilized to produce larvae that were then settled and reared to recruits. As of April 2021, when they were sampled for sequencing, 23 corals produced at CAS in 2019 and 16 corals produced at CAS in 2020 had survived for two years and one year, respectively. We sequenced the full genomes of the 39 offspring corals and their 15 potential parents to a median 26x depth of coverage. We find clear differential parentage, with some parents producing the vast majority of offspring, while the majority of parents produced no surviving offspring. After scanning 12.9 million single nucleotide polymorphisms (SNPs), we found 887 SNPs that may be under selection in the aquarium environment, and we identified the genes and pathways these SNPs may affect. We present recommendations for preserving standing genetic variation in aquarium-bred corals based on the results of this pilot project.

Characterization of guava (Psidium guajava L.) germplasm through morphological traits and SCoT markers

ABSTRACT Traditional breeding programmes have been limited to the selection and introduction of genotypes with promising agronomic characteristics, but studies focused on genetic diversity in the low hills of the North West(NW) Himalayas have not been conducted, which is very important for the identification of potential parents for breeding programmes in guava. In the present study, six best performing guava cultivars/hybrids were characterised using morphological descriptors and SCoT markers. Broad phenotypic variability among the guava cultivars/hybrids was detected using morphological descriptors. A set of 36 SCoT markers were used for polymorphism, out of which 31(86.1%) markers showed polymorphism, indicating high genetic variability in the guava cultivars/hybrids. During the analysis, 291 polymorphic amplicons were obtained, ranging from four to 19, with an average of 9.4 amplicons per primer and average polymorphic information content of 0.47.The UPGMA classified hybrids and cultivars into two groups. Based on morphological and molecular performance, L-49(Sardar) was ranked as the most promising cultivar for the low hills of NW Himalayan conditions. Morphological descriptors along with SCoT markers proved efficient in detecting the levels of genetic variability among the collections maintained in the field. These results can be used as an additional source of exploitation in guava breeding programmes.

Improvement of German Chamomile (Matricaria recutita L.) for Mechanical Harvesting, High Flower Yield and Essential Oil Content Using Physical and Chemical Mutagenesis.

Chamomile (Matricariarecutita L.) is one of the most important medicinal plants with various applications. The flowers and flower heads are the main organs inthe production of essential oil. The essential improvement goals of chamomile are considered to be high flower yield and oil content, as well asthe suitability for mechanical harvesting. The present study aimed to improve the flower yield, oil content and mechanical harvestability of German chamomile via chemical and physical mutagens. Three German chamomile populations (Fayum, Benysuif and Menia) were irradiated with 100, 200, 300 and 400 Gray doses of gamma rays, as well as chemically mutagenized using 0.001, 0.002 and 0.003 mol/mL of sodium azide for 4 h. The two mutagens produced a wide range of changes in the flowers' shape and size. At M3 generation, 18 mutants (11 from gamma irradiation and 7 from sodium azide mutagenization) were selected and morphologically characterized. Five out of eighteen mutants were selected for morphological and chemical characterization for oil content, oil composition and oil quality in M4 generation. Two promising mutants, F/LF5-2-1 and B/HNOF 8-4-2, were selected based on their performance in most studied traits during three generations, as well as the high percentage of cut efficiency and a homogenous flower horizon, which qualify them as suitable candidates for mechanical harvesting. The two mutants are late flowering elite mutants; the F/LF5-2-1 mutant possessed the highest oil content (1.77%) and number of flowers/plant (1595), while the second promising B/HNOF 8-4-2 mutant hada high oil content (1.29%) and chamazulene percentage (13.98%) compared to control plants. These results suggest that the B/HNOF 8-4-2 and F/LF5-2-1 mutants could be integrated as potential parents into breeding programs for a high number of flowers, high oil content, oil composition and oil color traits for German chamomile improvement.

On the Need to Expand the Legal Regulation of Surrogacy Relations in Russia

The subject of the study is the regulatory and legal provisions of the Institute of surrogacy in the Russian Federation. The object of this research is the concept and essence of surrogacy as a method of assisted reproductive technologies in accordance with the current legislation of the Russian Federation. The methodological basis is represented by a set of methods of scientific cognition of objective legal reality applied in the course of preparation and writing: comparative analysis (also known as the comparative legal method), as well as the formal legal method. In addition, the methods of scientific cognition of objective legal reality used by the author also include the logical method, system-structural analysis, and the method of legal modeling. The sharp drop in the birth rate in Russia in 2022 exacerbates the issue of the early legislative establishment of legal mechanisms that have not yet been used by the Russian state, but which are quite capable of assisting Russian citizens in the use of assisted reproductive technologies, overcoming infertility and, ultimately, in the exercise of their conventional and legal rights to create a family and procreation. The author conducted a sociological observation based on the materials of websites specializing in informing citizens about assisted reproductive technologies, identified the most typical problematic and conflict situations in the relationship of potential biological parents and potential surrogate mothers, made conclusions and suggestions to eliminate the identified problems from social practice. In particular, it is concluded that it is necessary to organize departments at maternity hospitals specializing in monitoring the condition of surrogate mothers and their implementation of medical recommendations, including compliance with the pregnancy preservation regime.

Interrelationship between grain yield components and nutritional quality traits in cowpea genotypes

Correlations and path coefficient analysis provide knowledge on trait interrelationships and potential for simultaneous, direct, or indirect selection in plant breeding. The objective of this study was to determine the genetic and phenotypic correlations as well as the path coefficient analysis among grain yield components and nutritional quality traits in cowpea genotypes. Data for grain yield components and mineral elements were collected from 70 cowpea genotypes planted at two environments in 2017/18 and 2018/19 seasons in South Africa. Grain yield had significant (P<0.05) positive phenotypic correlations with number of seeds per pod (SPP), indicating that selection of cowpea genotypes based on SPP could be effective in maximizing grain yield. The heat map showed that grain yield was strongly associated with number of branches (NB), SPP and number of pods per plant. Among the yield components, only SPP showed significant (P<0.05) positive phenotypic correlations with Zn, Mn, and Mg. Grain yield showed no genetic correlations with yield components and nutritional quality traits. Significant (P<0.05) positive genetic correlations were observed between yield components and most of the nutritional quality traits, indicating inherent association among the traits. Path coefficient analysis identified SPP and NB as major contributors to grain yield. The PCA identified cowpea genotypes such as ARC030, ARC011, ARC016, ARC024, NGOII, ARC032, IT90K59, and ARC047 with high grain yield and good nutritional quality traits that can be used further as potential parents for crop improvement through biofortification. The clustered heat map distingished five groups of cowpea genotypes and three of those were associated with good grain yield and nutritional quality traits which could make cowpea a good choice to combat food security and malnutrition in the world.

Comparative investigation of the genetic components of Withania somnifera L. yield and quality traits using multivariate and associations analysis in the Deccan plateau region

The vital herb ashwagandha was farmed for commercial purposes in India. This study aimed to estimate the nature and amount of genetic variation in the 20 attributes in the 29 genotypes of ashwagandha in order to understand the correlations and character contributions to dry root weight/plant and alkaloid content with the selection of potential parents for ashwagandha crop improvement. Twenty-nine ashwagandha genotypes were assessed using a range of genetic metrics, including analysis of variance (ANOVA), genetic variability components, correlation, principal component analysis (PCA), and Mahalanobis D2. The ANOVA confirms a large amount of variability in the genotypes/varieties under study. Out of twenty the four traits, namely fresh leaf weight per plant (X8), dry leaf weight per plant (X9), seed yield per plant (X13), and dry root weight per plant (X16)—indicates the presence of additive gene action in the current study were highly heritable and had a high genetic advance mean value. Starch estimation, main root length, and root diameter were found to be positively and significantly correlated with dry root production per plant and total alkaloid content. The principle component analysis (PCA) results showed that the first four PCA accounted for the bulk (79.56%) of the differences. All genotypes are divided into four clusters based on the distances between and within clusters. Based on the findings mentioned above, it is recommended that genotypes from clusters IV (Poshita, CIMAP-Chetak), cluster II (AKAS-10, AKAS-11, NMITLI-101, and NMITLI-118), and cluster I (AKAS-02, IC-286632, and CIMAP Pratap) be chosen for a different hybridization program. Based on the multidisciplinary investigation, some of the genotypes with desired qualities have been found. They can be employed in upcoming breeding programs to increase alkaloid content and dry root yield.

Evaluation of the fifth selfing generation of Madura Local Maize, Indonesia

The assembly of hybrid maize varieties with high production and early maturity is the right step to increase maize production on Madura Island, Indonesia. Assessment of the fifth generation selfing maize genotype aims to obtain potential parents that can be used in assembling hybrid maize varieties. This study aimed to evaluate the fifth selfing generation of Madura local maize, Indonesia. The study used a randomized complete block design with ten genotypes as treatment and repeated three times, so there were ten experimental units. The ten genotypes were G1= Tb-1-10-5, G2 = Tb-2-21-5, G3 = EL-1-26-5, G4 = EL-3-2-5, G5 = DL-2-11-5, G6 = DK-1-5-5, G7 = CTK-1-4-5, G8 = DBR-1-12-5, G9 = KRA-1-2-5, dan G10 = GL-1-6-5. Characters observed in this study were plant height, days of 50% tasseling, days of silking, harvest age, ear length, ear diameter, 100-kernel weight, and production per hectare. The eight characters observed in ten fifth-generation selfing maize had a low coefficient of variance (0.16-6.62%), indicating that the variation within the genotype was small. The genotypic coefficient of variation (GCV) is greater than the phenotypic coefficient of variation (PCV) in all observed characters. The heritability value in the broad sense of all observed characters is 0.81-0.99 (high). Production per hectare has a significant positive correlation with plant height, days to 50% tasseling, days to 50% silking, harvest age, ear length. G1, G2, and G5 were potential genotypes that could be used as parents in the assembly of high-production and early-maturity maize varieties.

Identification of Disease Resistance Parents and Genome-Wide Association Mapping of Resistance in Spring Wheat.

The likelihood of success in developing modern cultivars depend on multiple factors, including the identification of suitable parents to initiate new crosses, and characterizations of genomic regions associated with target traits. The objectives of the present study were to (a) determine the best economic weights of four major wheat diseases (leaf spot, common bunt, leaf rust, and stripe rust) and grain yield for multi-trait restrictive linear phenotypic selection index (RLPSI), (b) select the top 10% cultivars and lines (hereafter referred as genotypes) with better resistance to combinations of the four diseases and acceptable grain yield as potential parents, and (c) map genomic regions associated with resistance to each disease using genome-wide association study (GWAS). A diversity panel of 196 spring wheat genotypes was evaluated for their reaction to stripe rust at eight environments, leaf rust at four environments, leaf spot at three environments, common bunt at two environments, and grain yield at five environments. The panel was genotyped with the Wheat 90K SNP array and a few KASP SNPs of which we used 23,342 markers for statistical analyses. The RLPSI analysis performed by restricting the expected genetic gain for yield displayed significant (p < 0.05) differences among the 3125 economic weights. Using the best four economic weights, a subset of 22 of the 196 genotypes were selected as potential parents with resistance to the four diseases and acceptable grain yield. GWAS identified 37 genomic regions, which included 12 for common bunt, 13 for leaf rust, 5 for stripe rust, and 7 for leaf spot. Each genomic region explained from 6.6 to 16.9% and together accounted for 39.4% of the stripe rust, 49.1% of the leaf spot, 94.0% of the leaf rust, and 97.9% of the common bunt phenotypic variance combined across all environments. Results from this study provide valuable information for wheat breeders selecting parental combinations for new crosses to develop improved germplasm with enhanced resistance to the four diseases as well as the physical positions of genomic regions that confer resistance, which facilitates direct comparisons for independent mapping studies in the future.

Variation in protein content, starch components, selected minerals and their bioavailability in bambara groundnut accessions

IntroductionBambara groundnut is a highly nutrient dense underutilized orphan crop, and has the potential to address malnutrition and food security. The study objectives were to estimate the variation in the concentration of protein, starch, amylose, iron (Fe), zinc (Zn), phytic acid (PA) and mineral bioavailability, to identify superior bambara accessions and to determine the interrelationship between measured traits. Materialsand methods: Grain samples were collected from 59 accessions that were planted in two different locations over two seasons and used to measure the nutritional quality traits. Results: Significant variability among accessions in diverse locations and seasons for protein, Fe, Zn, and PA/Fe and PA/Zn ratios was observed. The average values of measured characteristics were protein (22.59 %), starch (36.52 %), amylose (21.15 %), Fe (38.83 mg kg−1), Zn (27.10 mg kg−1), PA (6239.24 mg kg−1), PA/Fe (17.74) and PA/Zn (22.87) content. Significant positive correlations between protein, Fe and Zn were observed and these traits were negatively correlated with starch, amylose, PA, PA/Fe and PA/Zn ratio. Accessions SB 4–4 A and M 3 were superior for more than one nutritional trait and had good mineral bioavailability. ConclusionSuperior accessions can be used as potential parents for the development of nutritionally improved bambara cultivars.

Mango seedling genotyping reveals potential self-incompatibility and pollinator behavior

Mango (Mangifera indica) is tropical fruit widely cultivated and appreciated for its sweet and aromatic fruit. There is great diversity among mango cultivars for important fruit quality and agronomic traits that could be leveraged as part of a mango breeding program. Historically, most genetic improvement of this species has been the result of chance seedlings. The recent publication of multiple mango genomes and availability of genomic resources is facilitating the efficient breeding of mango, but controlled pollination of mango is challenging with only a few out of thousands of panicle-borne flowers developing into fruit. Therefore, genotyping open-pollinated seedlings could be a labor-saving method to select favorable hybrids in a breeding program. An array of 384 single-nucleotide-polymorphism markers was used to genotype 140 mango cultivars and 575 mango seedlings from eleven open-pollinated populations in a mango diversity collection. Analysis of mango cultivars confirmed hybrid parentage in many instances and identified potential paternal parents for cultivars with unknown parentage. For the seedlings analyzed, the Dixon test of Gower's genetic dissimilarity (GD) values among identified triads revealed 161 significant triads (P≤0.05), indicating high confidence for paternal identification. The remaining triads had GD values less than 0.15 (n = 323), between 0.15 and 0.2 (n = 10), or between 0.2 and 0.3 (n = 5). In total, 70% of the hybrids were paired to a single paternal parent. Analysis of selfing rates indicated ‘Tommy Atkins’ had the highest selfing rate (40.4%) and ‘Glenn’ had the lowest (1.1%). Analysis of population structure and phylogeny divided the mango germplasm into three distinct clusters. The identified paternal pollen donors were mapped within a mango diversity collection and indicated mango pollinators can affect pollination beyond adjoining trees. This strategy can be used to aid mango breeding research and has identified intriguing hybrids for future evaluation.

Genetic Diversity of Tea Plant (Camellia sinensis (L.) Kuntze) Germplasm Resources in Wuyi Mountain of China Based on Single Nucleotide Polymorphism (SNP) Markers

Wuyi Mountain in Southeast China is the origin of black tea and oolong tea. It is also considered the ‘treasure trove of tea cultivars’ because of its rich tea germplasm resources. In the present study, the population structure and genetic diversity of 137 tea germplasms from Wuyi Mountain and its adjacent areas were analyzed by SNPs. The information index (I), observed heterozygosity (Ho), expected heterozygosity (He) and fixation index (F) polymorphisms of the selected SNPs were high, stable and reliable. Ho had an average of 0.389, while He had an average of 0.324, indicating that Wuyi Mountain tea germplasms had rich genetic diversity. The AMOVA results showed that genetic variation came mainly from intrapopulation variation, accounting for 66% of the total variation. The differences in the Fst and Nei values of tea germplasm between Wuyi Mountain and its adjacent areas are similar to the geographical differences. Multiple analyses based on high-quality SNPs found that the landraces of tea plants on Wuyi Mountain had different genetic backgrounds from the wild-type landraces and the landraces of Wuyi Mountain tea plants underwent population differentiation. This study provides a basis for the effective protection and utilization of tea germplasms on Wuyi Mountain and lays a foundation for identifying potential parents to optimize tea cultivation.
