Assessment of Genetic Diversity and Relatedness of Local Banana (Musa spp.) Cultivars in Malaysia Using Simple Sequence Repeat (SSR) Markers

Banana (Musa spp.) is an economically important crop widely consumed all over the world. Understanding the genetic diversity and relatedness between various banana cultivars is important to continuously improve its fruit characteristics, nutritional value, and disease resistance. This study aimed to develop a DNA fingerprinting panel using polymorphic simple sequence repeat (SSR) markers for the genetic characterisation of 11 banana cultivars in Malaysia. A total of 10 polymorphic SSR markers were developed into a multiplex PCR reaction and capillary electrophoresis to uniquely profile our collection of banana cultivars. The developed fingerprinting panel successfully amplified a total of 95 alleles, with 6 to 13 alleles per SSR marker. The average SSR marker polymorphic information content (PIC) value is 0.812, indicating the informativeness of the panel. Analysis of molecular variance (AMOVA) shows that 97% of the molecular variance from our banana collection is due to inter-variety genetic diversity, while the remaining 3% is due to intra-variety genetic diversity. A population structure analysis groups our collection of banana varieties according to the presence of at least one M. balbisiana (B) genome in their genetic makeup. The Cavendish variety, however, showed a distinct structure compared to the other cultivars. This SSR fingerprinting panel provides valuable insights into the genetic diversity and relatedness between banana cultivars in Malaysia. It has the potential to assist future banana breeding initiatives and serve as an effective quality control measure for verifying varieties in a tissue culture facility involved in banana planting materials production.

IMPLEMENTASI AGROEKOLOGI PADA SISTEM USAHA TANI DI PONDOK PESANTREN ANWARUSH SHOLIHIN PURWOKERTO

Islamic boarding school students are one of the human resources that have a strategic role in national development. In addition to studying religion, students are also expected to have adequate skills and knowledge in environmentally friendly agriculture. Many Islamic boarding schools carry out productive businesses in the agricultural sector as a source of income and learning facilities for students, one of which is the. This community service activity aims to improve the understanding and skills of students of Anwarush Sholihin Islamic Boarding School, Purwokerto Selatan, in applying the concept of agroecology in farming and environmental management. The activities included outreach, counseling, procurement of agricultural facilities, initiation of maggot cultivation, banana planting, fertilizer-making training, beekeeping training, and program evaluation. The results showed an increase of students' understanding and skills in implementing agroecology-based agriculture. In addition, the optimization of unused land around the Islamic boarding school has been converted to a banana plantation integrated with goat, magot, and beekeeping farms.

The Politics of Banana Planting in Waingmaw Township

Abstract: Since 2018, a steady stream of media reports has described the rapid expansion of tissue banana plantations in the Waingmaw area of Kachin State in Northeast Myanmar, noting the widespread environmental degradation and disenfranchisement of local residents. We conducted field research in two villages connected to banana plantations, interviewing residents, plantation workers, government officials, and health workers. Using assemblage theory, we analyze the local political ecology of food production, and how the particularities of local geography, especially in peripheral regions, result in different practical political settlements. These settlements involve a range of different actors including ethnic armed organizations, foreign merchants, government officials, and local brokers. Arrangements of power in border areas are implicit and negotiated, rather than explicit and formalized. These are appropriated through new spatial arrangements (e.g., banana plantations) and spatial relationships (e.g., migrant workers from Rakhine State) in which older identities and modes of living are redefined. A key component of this frontier assemblage is the banana itself, in particular, the practice of cultivating imported tissue strains which are reliant on imported technology and fertilizers. This, in turn, influences the form of the assemblage and power relations within it, illustrating the critical role of material and technological elements within assemblages.

Dynamic analysis of the microbial communities and metabolome of healthy banana rhizosphere soil during one growth cycle.

The banana-growing rhizosphere soil ecosystem is very complex and consists of an entangled network of interactions between banana plants, microbes and soil, so identifying key components in banana production is difficult. Most of the previous studies on these interactions ignore the role of the banana plant. At present, there is no research on the the micro-ecological environment of the banana planting growth cycle. Based on high-throughput sequencing technology and metabolomics technology, this study analyzed the rhizosphere soil microbial community and metabolic dynamics of healthy banana plants during one growth cycle. Assessing the microbial community composition of healthy banana rhizosphere soil, we found that the bacteria with the highest levels were Proteobacteria, Chloroflexi, and Acidobacteria, and the dominant fungi were Ascomycota, Basidiomycota, and Mortierellomycota. The metabolite profile of healthy banana rhizosphere soil showed that sugars, lipids and organic acids were the most abundant, accounting for about 50% of the total metabolites. The correlation network between fungi and metabolites was more complex than that of bacteria and metabolites. In a soil environment with acidic pH, bacterial genera showed a significant negative correlation with pH value, while fungal genera showed no significant negative correlation with pH value. The network interactions between bacteria, between fungi, and between bacteria and fungi were all positively correlated. Healthy banana rhizosphere soil not only has a stable micro-ecology, but also has stable metabolic characteristics. The microorganisms in healthy banana rhizosphere soil have mutually beneficial rather than competitive relationships.

Trophic interactions between predatory protists and pathogen-suppressive bacteria impact plant health.

Plant health is strongly impacted by beneficial and pathogenic plant microbes, which are themselves structured by resource inputs. Organic fertilizer inputs may thus offer a means of steering soil-borne microbes, thereby affecting plant health. Concurrently, soil microbes are subject to top-down control by predators, particularly protists. However, little is known regarding the impact of microbiome predators on plant health-influencing microbes and the interactive links to plant health. Here, we aimed to decipher the importance of predator-prey interactions in influencing plant health. To achieve this goal, we investigated soil and root-associated microbiomes (bacteria, fungi and protists) over nine years of banana planting under conventional and organic fertilization regimes differing in Fusarium wilt disease incidence. We found that the reduced disease incidence and improved yield associated with organic fertilization could be best explained by higher abundances of protists and pathogen-suppressive bacteria (e.g. Bacillus spp.). The pathogen-suppressive actions of predatory protists and Bacillus spp. were mainly determined by their interactions that increased the relative abundance of secondary metabolite Q genes (e.g. nonribosomal peptide synthetase gene) within the microbiome. In a subsequent microcosm assay, we tested the interactions between predatory protists and pathogen-suppressive Bacillus spp. that showed strong improvements in plant defense. Our study shows how protistan predators stimulate disease-suppressive bacteria in the plant microbiome, ultimately enhancing plant health and yield. Thus, we suggest a new biological model useful for improving sustainable agricultural practices that is based on complex interactions between different domains of life.

The contestations of diversity, culture and commercialization: why tissue culture technology alone cannot solve the banana Xanthomonas wilt problem in central Uganda

Several initiatives by the Government of Uganda, Research Institutes and CGIAR centers have promoted the use of tissue culture (TC) banana technology as an effective means of providing clean planting material to reduce the spread of Banana Xanthomonas wilt (BXW) but its uptake is still low. We examine factors that constrain uptake of tissue culture banana planting materials in central Uganda by considering the cultural context of banana cultivation. Data were collected using eight focus group discussions involving 64 banana farmers and 10 key informant interviews and subjected to thematic analysis. Results showed that banana cultivars in the study communities were important for food, cultural practices and medicine. Cultivars supplied through TC were based on commercial considerations focusing on market value and household income and insufficient attention was given to their cultural importance. Farmers regard banana from TC planting material to be incompatible with their tastes and preferences for traditional food and drinks, culture and medicine. Furthermore, the plantlets are perceived as complicated to use, and farmers report requiring more knowledge and information on how to plant and maintain the plantlets on-farm. In these aspects, TC planting material does not align with cultural values linked to societal welfare. Future efforts aimed at controlling pests and diseases would benefit from more location-specific and holistic approaches that integrate cultural dimensions alongside planting material hygiene, quality and vigor.

Molecularly Imprinted Photonic Crystals Based on Fusaric Acid for the Detection of Banana Fusarium Wilt

Banana Fusarium wilt is a soil-borne disease caused by Fusarium oxysporum f. sp. cubense (Foc) in which F. oxysporum f. sp. cubense race 4 (Foc4) could infect all kinds of banana and has caused great damage to the banana planting industry. The most important means to prevent and control banana Fusarium wilt in agricultural production is to control the spread and invasion of pathogens. Among them, the detection and determination of banana Fusarium wilt in the field is essential and thus is the basis of protection. Since fusaric acid (FA) is one of the specific products present during the metabolic processing of Fusarium wilt pathogens, by combining FA with molecularly imprinted photonic crystal (MIPC) technologies, a series of MIPCs based on monodispersed silica, FA, and cross-linked polymers, i.e., MIPC-FA, which could be recycled, were designed and prepared. It was found that the responses of MIPC-FA were affected by the cross-linking degree of the polymer matrix and the pH values. The results showed that MIPC-FA could effectively detect FA in a solution of FA in a minute scale, Foc4-containing medium, and banana plants infected by Foc4, and the response was related to the FA concentration, which makes it an effective and fast method to detect and determine banana Fusarium wilt caused by Foc4 in the field.

Study on environmental behaviour of fluopyram in different banana planting soil

Fluopyram is commonly used to control banana leaf spot, anthracnose, and scab in tropical agricultural areas. To explore its behaviour in tropical agricultural environments, dissipation, adsorption, and leaching behaviours of fluopyram in three typical banana planting soils were studied. Also, its dissipation and migration capabilities in different regions and different soil types were evaluated. The results showed that the dissipation of fluopyram was in accordance with the first-order kinetic equation in the three banana soils, but the degradation rates were quite different. The degradation half-lives in the Hainan latosol, Yunnan sandy soil, and Fujian Plain alluvial soil were 46.21 days, 36.48 days and 57.76 days, respectively. Fluopyram also exhibited high adsorption and low leachability in the three soils. The Fujian Plain alluvial soil had the highest adsorption capacity for fluopyram, while fluopyram had the low leachability in the Yunnan sandy soil.

Gender Roles in Sourcing and Sharing of Banana Planting Material in Communities with and without Banana Bunchy Top Disease in Nigeria

Banana bunchy top disease (BBTD) is the most devastating disease of banana and plantain (Musa spp.). The disease spreads through the use of infected vegetative propagules and the banana aphid (Pentalonia nigronervosa) is the virus vector. This study seeks to understand the gender dimensions and sociocultural aspects of banana seed (vegetative propagule) sourcing and sharing practices among men and women farmers, and its influence on BBTD spread and disease control efforts. Data were collected from 300 banana farmers (187 men and 113 women) in BBTD and non-BBTD areas in southwest Nigeria. The results revealed that seed sharing within the communities is a social responsibility with members expected to share banana seed with the needy mainly as gifts rather than sold for cash. Men farmers mostly sourced seed from old fields, while women sourced seed from relatives. Harvesting of banana seed was predominantly the responsibility of men with women as helpers. Both men and women farmers in the non-BBTD area cultivated larger farm sizes and harvested more banana planting material than farmers in the BBTD area. The existing seed sourcing practices among men and women farmers heighten the risk of BBTD spread. Awareness raising on disease spread through infected seeds should consider gender-differentiated roles and social practices to reduce its spread within communities.

This study aimed at assessing the level of mobile phone use in Ugandan agricultural extension, and to establish the extent to which mobile phone Viamo’s 3-2-1 service, hosted by Airtel Uganda, was being accessed and how the facility can be improved to boost banana productivity. The results of the study indicate that use of mobile phones for increased banana productivity were dependent on age, gender, household size, income and farming experience. Data collected show that the major information source by farmers was extension agents followed by phones and televisions. Focus group discussions revealed that most farmer participants owned phones (94.3%), had Airtel SIM cards and accessed Viamo service (65%). All respondents were aware of the Viamo service and majority got to know about the service through Airtel SMS notifications (83.3%). Farmers indicated that the four most sought after information elements for increasing banana productivity included material on weather forecasts, pest and disease control, fertilizers and their usage, and markets and their location. The study reveals information gaps with respect to pests and disease diagnosis and management, market prices, weather information, mulching and weeding in different terrains, and sources of clean banana planting material. It was concluded that the service is relevant and contributes to improving farmer knowledge on good banana farming practices. A further step will be to scale up use of the 3-2-1 service for agricultural purposes at country and regional levels.

Not only the seed matters: Farmers' perceptions of sources for banana planting materials in Uganda.

The adoption of improved seed and other planting material in developing countries shows mixed results despite their potential to increase agricultural productivity. To arrive at a better understanding of the observed adoption rates, a lot of research is focused on finding the cultivars and variety traits that are attractive to farmers. Given smallholder farmers’ seed sourcing practices are often influenced by social ties and cultural norms, it is also relevant to understand where and why farmers seek to acquire planting material. In this study, means-end chain analysis was applied to understand farmers’ perceptions of formal and informal sources of banana planting material. Means-end chain analysis allows respondents to select and verbalize their own constructs to evaluate a product or service. These personally relevant constructs are subsequently linked to their personal goals via laddering interviews. We interviewed 31 Ugandan banana farmers from Western and Central region. Farmers associated formal sources mainly with improved cultivars, tissue culture plantlets and low levels of diversity. Informal seed sources were mostly associated with traditional cultivars, suckers and high levels of diversity. The goals farmers pursued while acquiring planting material, such as financial gains, food security, and to sustain and develop the household, were fairly similar among different groups of farmers. The means through which farmers aimed and preferred to pursue these goals differed and could be related to aspects such as gender, production scale and production goals. These differences among farmers preferences for particular sources indicate that not only cultivar traits should be tailored to farmers’ preferences and needs, but also the characteristics of the sources from which farmers access planting material.

Forecasting Banana Harvest Area and Production in Turkey Using Time Series Analysis

In this study, 1961–2015 period FAOSTAT data of banana harvest area and production in Turkey was modeled with the objective to forecast banana harvest area and production for the 2016–2025 period. Stationarity was provided with taking the first difference of the time series. Several Autoregressive Integrated Moving Average (ARIMA (0,1,1), ARIMA (1,1,0) and ARIMA (1,1,1)) and Exponential Smoothing (Holt, Brown and Damped) models were tested. Brown exponential smoothing model was determined as the most suitable one for forecasting banana harvest area and production. Banana harvest area was forecasted to be 6175 ha in 2016 and increase to 9733 ha in 2025 year. Banana production was predicted to show a substantial increase for the 2016–2025 period, from 291,667 to 482,093 t. Briefly, the results of this study could help policy makers to develop better macro-level policies for food security and sustainability, as well as to establish better banana planting area and production strategies in Turkey for the future.

Empowerment of Farmer Community Group in Sampali Village Together with Students of Agriculture Faculty Medan Area University in Barangan Banana Plants Development with Tissue Culture Banana Seeds,Suckers and Applications of Mycorrhiza

Sampali Village is an agricultural area that is very suitable for banana planting. Various types of bananas found in the village include Barangan, Kepok, Molen, Raja and banana Nangka . Banana shoots from harvested mother plants are used for development in new areas. Banana seedlings from the suckers appear healthy, but often these suckers die after 1-2 months of planting in new areas. This is because these bananas have been infected with fungal pathogen wilt caused by Fusarium oxysporm f. sp cubense and Ralstonia syzygii subsp. celebesensis causes of blood diseases. Both of these pathogens are the main cause of the low quality of banana seeds. The use of low-quality banana seedlings (sapling sources), high pest and disease attacks are the factors causing the reduced amount of banana planting land which results in low banana production in Sampali Village, Percut Sei Tuan District, Deli Serdang Regency. Banana farmer groups in the village of Sampali have never used and planted banana seedlings that were propagated by tissue culture. The objectives of the activity were: 1. Socialization and practice of propagation of banana seedlings from sucker . Mycorrhizal inoculant application when planting seedlings in a polybag. To increase the knowledge of farmer group members and also the students of Agricukture Faculty,Universitas Medan Area the learning of banana propagation techniques is carried out in vitro at the Balai Benih Induk Hortikultura, Gedung Johor Medan . The method used to solve the above problems is the provision of material, the practice of making banana seedlings through the propagation of tillers and a visit to the Balai Benih Induk Hortikultura, Gedung Johor Medan. At the end of the activity, an increase in the knowledge and skills of participants in providing quality banana seeds is the source of banana propagation in the village Sampali

Recognition of Banana Fusarium Wilt Based on UAV Remote Sensing

Fusarium wilt (Panama disease) of banana currently threatens banana production areas worldwide. Timely monitoring of Fusarium wilt disease is important for the disease treatment and adjustment of banana planting methods. The objective of this study was to establish a method for identifying the banana regions infested or not infested with Fusarium wilt disease using unmanned aerial vehicle (UAV)-based multispectral imagery. Two experiments were conducted in this study. In experiment 1, 120 sample plots were surveyed, of which 75% were used as modeling dataset for model fitting and the remaining were used as validation dataset 1 (VD1) for validation. In experiment 2, 35 sample plots were surveyed, which were used as validation dataset 2 (VD2) for model validation. An UAV equipped with a five band multispectral camera was used to capture the multispectral imagery. Eight vegetation indices (VIs) related to pigment absorption and plant growth changes were chosen for determining the biophysical and biochemical characteristics of the plants. The binary logistic regression (BLR) method was used to assess the spatial relationships between the VIs and the plants infested or not infested with Fusarium wilt. The results showed that the banana Fusarium wilt disease can be easily identified using the VIs including the green chlorophyll index (CIgreen), red-edge chlorophyll index (CIRE), normalized difference vegetation index (NDVI), and normalized difference red-edge index (NDRE). The fitting overall accuracies of the models were greater than 80%. Among the investigated VIs, the CIRE exhibited the best performance both for the VD1 (OA = 91.7%, Kappa = 0.83) and VD2 (OA = 80.0%, Kappa = 0.59). For the same type of VI, the VIs including a red-edge band obtained a better performance than that excluding a red-edge band. A simulation of imagery with different spatial resolutions (i.e., 0.5-m, 1-m, 2-m, 5-m, and 10-m resolutions) showed that good identification accuracy of Fusarium wilt was obtained when the resolution was higher than 2 m. As the resolution decreased, the identification accuracy of Fusarium wilt showed a decreasing trend. The findings indicate that UAV-based remote sensing with a red-edge band is suitable for identifying banana Fusarium wilt disease. The results of this study provide guidance for detecting the disease and crop planting adjustment.

Culturally embedded practices of managing banana diversity and planting material in central Uganda

ABSTRACTFormal seed systems aim to provide farmers with high-quality planting material that meets evolving demands and cultivation challenges. East African banana (Musa sp.) systems rely strongly on informal seed exchange. For seed system interventions to have a larger and more sustainable impact in such a context, it is necessary to better understand the informal seed system. We studied the management and replacement dynamics around banana suckers and mats by smallholder farmers in Central Uganda. Data were collected through Focus Group Discussions (n = 4) and semi-structured interviews (n = 23). This study showed that, on average, banana farmers grew 10 different banana cultivars to ensure year-round harvesting and to accommodate multiple consumption and cultural needs. They included cultivars from the formal seed system within their portfolios of banana cultivars while also conserving cultivar diversity. Farmers used a broad array of evaluation criteria to select suckers and preferred to use known sources to assure plant quality. Household characteristics, such as age or wealth, are determinants of mat management and replacement. We concluded that a flexible blend of formal-informal approaches to developing the banana seed system is needed to meet the multiple needs of farm households and to support them in improving productivity and dealing with emerging challenges.

As T. hawaiiensis has a marked thigmokinetic behavior, invasive capacity, high fecundity, and a short life-cycle, it is a potential worldwide pest of numerous plants, such as mango, banana, citrus, tea, coffee, and many horticultural plants. At present, T. hawaiiensis is known to cause serious damages to all species of banana crops cultivated in China. In particular, the thrips has been a key pest of the banana crops at the flowering stage, leading to large annual economic losses because of yield reductions and management costs. Understanding the population dynamics of a particular pest is important to monitor and predict the occurrence of the pest, and then proposing a cost-effective and eco-friendly integrated pest management (IPM) strategy. To date, however, the life history characteristics of the field T. hawaiiensis population remain largely unknown. In the present study, field-based experiments were conducted to investigate the population activity, rhythm, dynamics, spatial distribution pattern, and sex ratio of T. hawaiiensis. Moreover, 3 major banana planting areas, Chengmai of Hainan, Yulin of Guangxi, and Jinghong of Yunnan and 3 species of banana plants, Musa cavendish AAA, Musa acuminata Lour, and Musa paradisiaca AA were selected for the experiments. The blue-sticky cards and field survey were used for the experiments. All of these works were carried out from 2016 to 2018. Our results revealed that the adult T. hawaiiensis were active in the heights from 0.5 m to 15 m and most of the thrips were captured in the heights from 2 m to 6 m, indicating that the thrips population could be significantly correlated with the height. The field survey also revealed that T. hawaiiensis had a similar trend of daily activity rhythm in sunny-, cloudy-, and rainy-day, showing that the peak period was from 12:00 am to 16:00 pm. The thrips were not active at night and in the cloudy-, and rainy-day. The population dynamics of T. hawaiiensis was not influenced by the banana species and planting areas, with a similar pattern of population dynamics in the banana orchards tested. Importantly, it seemed that the banana growing season played a key role in the growth and declining rhythm of the thrips population, showing that T. hawaiiensis exhibited a single-peaked preference. A rapid population increase was observed during the flower-bud stage, and the peak time was in the flowering stage, while few of the thrips occurred in the other crop season. Aggregation index and Taylor regression analysis revealed that T. hawaiiensis had an aggregating distribution in the banana orchards. Finally, sex ratio analysis demonstrated that T. hawaiiensis was a female-dominant species, with approximately 70% female rate. Overall, the current study helps in understanding the population activity rhythm, dynamics, and spatial distribution pattern of adult T. hawaiiensis in banana orchards. These results would expand the basic knowledge of the ecological characteristics of T. hawaiiensis, providing useful information for implementing better forecast system and integrated pest management strategies for T. hawaiiensis control programs. 参考文献 相似文献 引证文献

Variation in banana prices in the Burhanpur market, Madhya Pradesh

Banana (Musa sp) is the most important fruit crop of Maharashtra and Madhya Pradesh. The banana prices in Burhanpur market for five years (2013–14 to 2017–18) were observed for their variation and skewness. It was indicated that highest maximum and minimum banana price variation was recorded in quarter Q1 (Jan-March) however middle price variationwas more during Q3 (July-Sept). The least variation for maximumprice was during Q3 and middle and minimal banana price variation was recorded in Q2 (April-June). All the types of banana prices studied did not follow normal distribution curve. It was leptokurtic for all types of prices studied. The minimum and middle banana prices showed negative skewness for Q1, Q2 and Q4 and positive for Q3. However maximum price showed negative skewness for Q2 and Q4 (Oct-Dec) and positive for Q1 and Q3. The year-wise quarterly graph indicated that average minimum, middle and maximum prices were very fluctuating in nature. It was concluded that the prices of banana were not stable at Burhanpur market of Madhya Pradesh. Thus this information may be useful for further planning of banana planting, harvesting and marketing.
