Polyphenolic Compounds in the Stems of Raspberry (Rubus idaeus) Growing Wild and Cultivated.

The stems of Rubus idaeus L., a byproduct of the fruit-food industry, are known sources of bioactive compounds. The main objective of this study was to investigate the composition of polyphenolic compounds in R. idaeus stems. Seven cultivated raspberry varieties, thirteen garden samples, including five well-known raspberry varieties, and thirteen wild raspberry samples from different locations in Estonia were analyzed. The HPLC-MS method detected 62 substances, of which 42 were identified, 12 were tentatively identified, and 8 compounds remained unknown. Protocatechuic acid pentoside was dominant in most varieties and in all garden and wild raspberry samples. Dihydroxybenzoic acid hexoside 1, p-coumaroyl quinic acid 1, quercetin 4'-glucuronide, and p-coumaric acid glycoside were found in significant quantities. Correlations among the contents of individual compounds were established. When studying the dynamics of polyphenolic compound accumulation in, for example, the GR1 sample over a year, it was found that, in raspberry stems, the largest amount of them accumulated in April and slightly less in January and October. Investigating the dependence of the accumulation of polyphenols on the parts of the stem, it was found that the upper parts have the highest phenolic contents. Therefore, it is recommended to harvest approximately the upper third of the stem.

Aspects of medium-term in vitro storage of raspberry varieties (Rubus idaeus L.)

The study aims to optimize the procedure for storing 12 varieties of Rubus idaeus L. of different fruiting types. The experiment used 1/2 Murashige and Skoog (MS) medium supplemented with agar (6.8 g/L), sucrose (20 g/L), and 6-benzylaminopurine (0.3 mg/L). The effects of temperature (+23 ℃ and +15 ℃) were examined, as well as that of a retardant, chlorocholine chloride at 0.2 g/L (CCC), used as part of the nutrient medium. A high percentage of viable explants (48.7- 73.0 %) was found to survive up to nine months under different cold storage conditions. From month 9 to month 12, the percentage of viable explants decreased (by 1.3-2.1 times depending on storage conditions). It was found optimal to store the studied varieties of R. idaeus in vitro at a lower temperature (+15℃) on 1/2 MS medium supplemented with 0.3 mg/L of 6-benzylaminopurine without the addition of a growth inhibitor. After 12 months of storage, the percentage of viable explants amounted to 56.9. The growth percentage of viable explants after in vitro storage at +15 ℃ on media without CCC amounted to 98.6, with an average propagation factor of 5.6, number of microshoots of 2.7 pcs./explant, and microshoot length of 1.3 cm. The presence of CCC in the medium was noted to reduce the growth rate of explants, while adversely affecting the percentage of viable explants. Thus, after 12 months of in vitro storage at +15 ℃ on media with the addition of CCC, the percentage of viable explants amounted to 39.2 %. It was noted that from month 3 to month 12 of storage at +15 ℃ on nutrient media with the addition of CCC, the number of microshoots and their length changed insignificantly (by 1.2 and 2.6 times), as compared to the indicators of microshoots cultivated in a grow room (by 1.8 and 3.3 times). The development of explants of the studied R. idaeus genotypes after in vitro storage was found to be affected by the type of fruiting and varietal features of the crop.

Evaluation of Growth and Energy Parameters of One-Year-Old Raspberry Shoots, Depending on the Variety

The article examines the influence of six varieties of primocane raspberries, Rubus idaeus L., on the growth parameters and energy properties of the biomass. The unique aim of this study was to show the impact of primocane raspberry varieties, grown for a single harvest, on the growth parameters of the bushes and the energy and emission characteristics of the biomass obtained from the pruned canes. To the best of our knowledge, there is no such analysis connected to varieties of raspberries available in the literature. The following primocane raspberries were assessed: Polana, Polesie, Delniwa, Poemat, Polonez, and Poranek. Among the studied raspberry varieties, Polana was characterized by the highest number of side shoots and the greatest sum of the shoot lengths, while the Polonez variety was characterized by the highest average shoot length and shoot thickness. In the tested raspberry varieties, the weight of the shoots per hectare varied significantly, ranging from 6.06 t in the Poranek variety to 9.05 t in the Delniwa variety. It was shown that the raspberry variety had a significant impact on the higher heating value (HHV) and the lower heating value (LHV). The lowest energy value was found in the Delniwa (HHV—17.32 MJ·kg−1; LHV—16.07 MJ·kg−1) and Polana (HHV—17.33 MJ·kg−1, LHV—16.19 MJ·kg−1) varieties, and the significantly highest value was observed in the Poranek variety (HHV—17.63 MJ·kg−1, LHV—16.39 MJ·kg−1). The assessment of the total volume of exhaust gases showed the highest value of this parameter for the Polesie and Delniwa varieties (6.89 m3·kg−1), with the lowest for the Polana variety (6.69 m3·kg−1).

Comparison of modern raspberry varieties long cane

Relevance. Modern raspberry varieties (Rubus idaeus L.) have great potential for cultivation using Long Cane technology.Methods. The study compared raspberry varieties Ovation, Wengi, and Vajolet. Seedlings were obtained from root cuttings, then grown from April 2021 to July 2022 for the summer harvest and from April 2022 to October 2022 for the fall harvest.Results. It has been established that varietal characteristics and the fruiting period significantly affect the indicators. The largest fruits are in the Wengi variety (length 25.5 mm, diameter 24.3 mm, weight 7.2 g), the smallest are in the Ovation variety (length 22.2 mm, diameter 22.5 mm, weight 4.9 g). When observing varieties at different ripening periods, it was found that the fruit length (27.3 mm) and fruit weight (8.3 mm) during the summer fruiting period are maximum in the Wengi variety, and minimum in the Vajolet variety. The amount of sugar ranges from 11 to 13°Bx, the percentage of ripe fruits from 84.5 to 94.5. The difference between the Wengi and Ovation varieties in terms of vegetative characteristics at different growing periods has been reliably proven. During the summer fruiting period, the yield per shoot for Wengi was 2615 g, for Vajolet – 485 g. The Wengi variety was distinguished by its maximum length (27.3 mm) and fruit weight (8.3 g). Based on all the indicators, the most promising varieties for summer fruiting are Wengi and Vajolet, and for autumn fruiting – Ovation.

Improvement of the clonal micro-propagation technology elements for raspberries of various fruiting types

The results of research on clonal micropropagation of 17 raspberry varieties of the Altai and European selection are presented. Recently, researchers have been focusing on creating a universal nutrient medium that would be equally suitable for any variety of a particular plant species. This is especially important for mass clonal micropropagation in production nurseries. The regeneration potential of the raspberry varieties of different types of fruiting at each stage of reproduction has been assessed. At the stage of actual micropropagation, it was found that Driver and Kuniyuki medium in our modification was superior to the Murashige and Skoog medium in terms of the shoot length and averaged 9.0 mm for common type varieties and 12.3 mm for remontant varieties. This made it possible to eliminate the additional stage of elongation of the microshoots. Also, the appearance of microshoots improved on the new medium. It was found that for raspberry, regardless of its type, the optimal concentrations of the growth regulators lie in the following range: cytokinin 6-benzylaminopurine (BAP) 2.5–3.5 μM together with auxin ß-indolyl butyric acid (IBA) 0.5–0.7 μM. At the stage of rhizogenesis, the best results were shown by the Driver and Kuniyuki medium with 2-fold reduced content of all main components and with the addition of 2.0 μM IBA at the passage duration of 21 days. After that, all microcuttings with and without roots underwent the adaptation stage – growth completion in neutral substrates for 56 days under ex vitro conditions in a vegetation room. In most cases, there were no statistically significant differences in the length and number of leaves regardless of the presence or absence of roots at the initial stage of adaptation. By the end of this stage, 100% of the adapted raspberry plants of the usual type of fruiting and 98% of the remontant type were obtained.

Evaluation of raspberry drought tolerance

Physiological parameters of drought tolerance of fi ve raspberry varieties (‘Meteor’, ‘Gusar’, ‘Lavina’, ‘Patricija’, and ‘Ulyabka’) and seven selected raspberry forms (4-122-2, 6-125-3, 1-76-1, 6-125-4, 2-83-21, 1-76-25, 2-90-3) were investigated. Experiments were conducted in 2022–2023 at the Kokinsky experimental station of the Federal Horticultural Center for Breeding, Agrotechnology and Nursery (Bryansk Oblast) and at the Center for Collective Use of Bryansk State Agrarian University. Drought tolerance was assessed based on the indices of total leaf water content, water defi cit, and water-retaining capacity in the phenophases of budding (May) and fruiting (July). The analysis showed that within one vegetation period, the total leaf water content and water-retaining capacity decreased from the phase of budding to that of fruiting, compared to water defi cit, which showed an inverse trend. The water-retaining capacity of the studied varieties was found to be higher in a drier season than in a moderatelyhumid year. A signifi cant variability among genotypes was observed in terms of water regime. During the fruiting phase, the total leaf water content decreased to an average level in all the studied genotypes (less than 70.0 %), except for the ‘Gusar’ and ‘Lavina’ varieties which demonstrated lower levels (less than 60.0 %). Forms outperforming in a number of leaf water regime parameters were identifi ed. Thus, the ‘Meteor’ variety, although showing high values of water content in the budding phenophase, was characterized by low water losses after 6-hour wilting (less than 30.0 %) and a leaf water defi cit (less than 10.0 %). Water defi cit in the ‘Ulyabka’ variety, as well as 6-125-4 and 2-90-3 selected forms, exceeded 10.0 % in the fruiting phenophase, corresponding to the average level of drought tolerance. The 2-83-21 form showed a reduced water-retaining capacity in the fruiting phenophase (water losses exceeded 30.0 %).

The influence of humus extract on the quality of raspberry (Rubus idaeus L.)

This paper analyzes the influence of foliar fertilizer based on humus extract on some of the elements central to the quality of the Polka raspberry variety in the area of the city of Bihać. The research was conducted in 2015 according to the control and treatment system. A foliar fertilizer based on humus extract was used for the treatment. A total of 12 quantitative and qualitative properties were analyzed: content of total sugars, reducing sugars, invert sugars, sucrose, water content, dry matter, total acidity, vitamin C, total phenols, total flavonoids, antioxidant capacity, and fruit mass. After the analyses were completed, it can be concluded that fruits of raspberry plants treated with humus extract have an almost identical value of total acidity (1.65%) as found in control. However, treatment with a humus extract slightly lowered the content of total phenols and vitamin C. Based on the results obtained, it was shown that the foliar fertilizer based on the humus extract did not have a positive effect on certain chemical and antioxidant properties of the raspberry fruit.

Screening of raspberry <i>Rubus idaeus</i> plants of the FSBSO ARHCBAN collection for a marker associated with the <i>RBDV</i> virus resistance trait

Viral damage produces a significant detrimental effect on raspberry plantations. Raspberry bushy dwarf virus (RBDV) appears particularly harmful, capable to significantly reduce raspberry yields. The high prevalence of RBDV is due to its ability to be transmitted by pollen and the absence of visible symptoms on plants during the first stages of infection. Breeding of RBDV-resistant varieties can significantly reduce the damage caused by RBDV infection. Therefore, a search for genetic markers of RBDV resistance is considered particularly relevant. At present, the Bu gene is identified with the dominant mode of inheritance associated with the trait of resistance to RBDV. A number of markers, successfully tested on a large sample of foreign raspberry varieties, enable resistant phenotypes to be predicted with high accuracy. However, their testing on Russian varieties is still to be carried out. The paper presents the results of PCR-mediated searching for a diagnostic fragment of the marker rasp_N_gene_1202, associated with the trait of raspberry resistance to RBDV, involving 14 raspberry varieties from the collection of the Federal Horticultural Center. The research was conducted to test the efficacy of the rasp_N_gene_1202 marker in order to identify RBDV-resistant genotypes. The experiment involved 12 Russian varieties and two foreign varieties used as positive control. The work was carried out in the Laboratory of Reproductive Biotechnology of Federal Horticultural Center for Breeding, Agrotechnology and Nursery in 2023. Based on the analysis, a potentially RBDV-resistant variety ‘Arisha’ was identified. In addition, the diagnostic fragment was detected in moderately resistant and resistant varieties: ‘Gussar’, ‘Orangevoye Chudo’ and ‘Poklon Kazakovu’. However, no diagnostic fragment was detected in the resistant varieties ‘Lavina’ and ‘Medvezhonok’. For this reason, the investigated marker is recommended to be used in combination with other known markers of resistance to RBDV in order to increase the reliability of screening results. No diagnostic DNA fragment was detected on varieties with susceptible phenotype using the tested marker. The obtained data can be used in the selection process to develop new RBDV-resistant varieties.

A new raspberry ketone synthesis gene RinPKS4 identified in Rubus idaeus L. by transcriptome analysis.

Raspberry ketone accounts for the characteristic aroma of the raspberry fruit. In order to explore the genes involved in raspberry ketone synthesis, the transcriptome in fruit tissues of two red raspberry varieties "Polka" and "Orange legend", were sequenced and 24213 single genes were obtained. As the red raspberry fruit ripening, genes involved in flavonoid and anthocyanin synthesis were up-regulated, while those associated with lignin synthesis were down-regulated. A gene (RinPKS4) highly related to raspberry ketone synthesis was identified by transcriptome analysis, and RinPKS4 gene was over-expressed in raspberry in order to further understand the function of RinPKS4 gene in raspberry ketone synthesis. The results showed that the gene expression level of RinPKS4 in the leaf tissues of a transgenic lines increased by about 4-fold and the content of raspberry ketone increased by 42.64% compared with the wide type. This study lays a theoretical foundation for further study on the synthesis and regulation of raspberry ketone in red raspberry.

ИНТРОДУЦИРОВАННЫЕ СОРТА МАЛИНЫ КАК ИСТОЧНИКИ В СЕЛЕКЦИИ

The study was carried out to identify the breeding potential of introduced raspberry varieties of different geographical origins. The work was carried out in 2018-2022 in Bryansk region. The material for the study is 17 raspberry varieties of foreign selection, the control is the late-ripening variety Lavina. The following indicators were taken into account: field winter hardiness, degree of disease damage, duration of fruiting, productivity, productivity, mechanical properties of berries and taste. It has been established that it is inappropriate to grow some of the varieties in the conditions of central Russia without shelter for the winter. The varieties Uslada, Cascade Delight, Phenomenon, and Lavina were characterized by high winter hardiness with a degree of damage of no more than 1.0 points. For resistance to Didymella applanata Sass. (defeat up to 1.5 points) varieties were selected - Glen Ample, Sokolica, Radziejowa, Cowichan and the control variety Lavina, to Botrytis cinerea Pers. (loss up to 1.5 points) – Laszka, Tadmor, Chemainus, Sokolica, Radziejowa, Glen Ample, Cascade Delight, Octavia. The varieties Sokolica and Radziejowa were characterized by high field resistance to a complex of pathogens. Most genotypes are distinguished by medium-late fruit ripening (starting from the middle of the second decade of July). According to the components of productivity, complex sources of their high manifestation have not been identified, however, the varieties Laszka, Tadmor, Chemainus, Sokolica, Radziejowa, Glen Ample, Fenomen, Cowichan, Benefis, Glen Magna, which form fruits with an average weight of 3.8...4.4 g, can be used in breeding to increase the level of large fruit. According to the results of studying the mechanical properties of raspberry fruits, the varieties Laszka, Tadmor, Sokolica, Chemainus, Cascade Delight were characterized by increased strength (6.2...6.8 N) and optimal force of separation of berries (0.5...0.6 N) from the fruit. In terms of taste, the yellow-fruited varieties Valentina and Anne stood out, as well as the Uslada variety with a tasting score of 4.5 points. The varieties Tadmor, Chemainus, Glen Ample, Cascade Delight, Cowichan, Benefis, Glen Magna had a dessert taste (4.0...4.3 points), but without a “raspberry” aroma.

STONE FRUITS AS VALUABLE SOURCES OF PECTIN

The article contains the results of the studies on the content of pectic substances in three pomological varieties of apricot fruits, in three pomological varieties of peach and three pomological varieties of plum fruits grown in the climatic conditions of the Republic of Uzbekistan. The studies have shown that stone fruits as apricots, peaches and plums grown in Uzbekistan are characterized by a high content of pectin. According to our research, the variety Yubileyniy (anniversary) Navoi turned out to be the richest in pectic content from the studied fruit varieties, where the average content is 1.32%; in the Raspberry variety of peaches it is 1.12%; in the Violet Hungarian variety of plums, the average content is 1.32%. In all other studied varieties of apricot, peach and plum fruits, the content of pectic substances is more than one percent, with the exception of the fruits of the Yaichnaya (eggy) yellow plum variety where the average content of pectic substances is 0.93%. Due to the high content of pectic substances with good gelling properties, the studied pomological varieties of stone fruits can be successfully used to obtain a number of confectionery products with a jelly-like consistency.

The purpose of the study is to study the timing of the onset of phenological phases and assess the adaptive abilities of introduced raspberry varieties to changes in meteorological factors in the Cis-Ural forest-steppe zone of Bashkortostan. The results of studying the phenological phases of 11 raspberry varieties of different ripening periods are presented. The research was carried out at the Kushnarenkovskiy Breeding Center of the BNIISH UFITs RAS in 2016-2021. Observations were carried out in accordance with the "Program and methodology for the study of variety of fruit, berry and nut crops". It has been established that the timing and duration of the passage of the phenological phases of raspberries are significantly affected by weather conditions. It is noted that all studied varieties show low resistance to return frosts. The beginning of vegetation in the studied varieties, on average, was noted in the first decade of May. Raspberry blossom took place from 6 to 17 June. The ripening of raspberries began in the first decade of July. The fastest rates of raspberry development were noted in 2021 at an average daily air temperature of 18.8ºС, flowering took place on May 18, ripening on June 16, 15-24 days ahead of multi-year periods, the duration of flowering, ripening and interphase periods also decreased. The sum of effective temperatures for the onset of the "beginning of flowering" phenological phase was 524ºС; the onset of the phase "beginning of maturation" 1063ºС. It was revealed that raspberry varieties Novosti Kuzmina, Barnaulskaya, Chelyabinskaya krupnoplodnaya, Brigantina had the highest resistance to changes in environmental factors in the conditions of the republic.
