“…Out of ten screened genotypes of mung bean under natural field conditions against yellow mosaic virus disease, only two genotypes (IPM 02-3 and IPM 0205-7) were found completely free from the disease and plant had maximum chlorophyll content whereas, IPM-409-4 and RMG 991 were found resistant and chlorophyll content was low as compared to highly resistant varieties. Similar result was obtained by Darshan et al [14]. They screened 35 mung bean genotypes against MYMV.…”

Experiment was conducted to identify the resistant Mung bean varieties against MYMV in Kharif during 2017. Ten Indian mung bean genotypes obtained from AICRP on Arid legumes, RARI, Durgapura, Jaipur, were used in the screening experiment and the obtained results revealed that there was significant variation among the genotypes for resistance against MYMV. Based on the average MYMV score, only two genotypes (IPM 02-3 and IPM 0205-7) were found completely free from the disease and the plants had maximum chlorophyll content whereas IPM-409-4 and RMG 991 were found resistant and chlorophyll content was low as compared to the highly resistant genotypes. The rest of six genotypes observed moderately resistant, moderately susceptible, susceptible and highly susceptible to the disease.

“…As a result, the identified resistance lines can be used for further reactivity confirmation as well as the use of certain progenies in breeding programs to produce Mungbean Yellow Mosaic Virus (MYMV) resistant cultivars with good performance. Similar results were observed byKingsly et al (2015);Sudha et al (2013);Kabi et al (2017) andDharajiya et al (2018).…”

Background: Despite the best efforts for improving the greengram varieties, the yield potential of this crop remains low owing to both biotic and abiotic factors. Yield losses caused due to various diseases were estimated to be 24-67 per cent in anthracnose, 80-100 per cent in mungbean yellow mosaic virus and 40 per cent due to powdery mildew So, the use of resistant cultivars is the most effective and eco-friendly method of managing the disease. Methods: A series of field experiments spanned over seven years (2014-2021) were conducted at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad, Karnataka. In the first set of experiments, the material comprised of eight varieties of greengram which were treated with 20kR gamma radiation. M1was planted in Kharif 2014 and each variety was bulk harvested. M2 was planted in summer 2014 and individual plant selection was carried out. Mutant families were advanced to the further generation in Kharif 2015 and Rabi 2015. The M2 mutants were scored for their reaction to anthracnose, cercospora leaf spot and powdery mildew diseases with respective susceptible and resistant checks. In another set of experiments aimed at developing MYMV tolerant genotypes, an investigation was carried out with 168 F2 individuals derived from crossing Vigna trilobata and DGGV2. One row infector line of DGGV-2 was raised after every three test entries to study the reaction to MYMV. Three rows of susceptible check was planted all around the border to ensure enough inoculum load. Of the 168 F2 individuals, two lines showed resistance to MYMV. They were stabilized through a series of selfing generations. Result: Evaluation of advanced breeding lines for their reaction to various foliar diseases revealed that the advanced breeding lines DGG-203, DGG-206, DGG-208, DGG-21, DGG-80, DGG-273, DGG-274, DGG-275, DGG-262, DGG-263, DGG-264, DGG-82, DGG-200, TARM-1 (C), DGG-215-5, DGG-302, DGG-152, IPM-3-2, DGG-20, DGG-73, IPM-14-10, DGG-121, DGG-250, DGG-109, DGG-96 had seed yields ranging from 9.8 g to 12.4 g and moderately resistant to both anthracnose and CLS. The breeding lines DGG-203, DGG-206, DGG-21, DGG-273, IPM-3-2 (Check), DGG-96 have recorded combined resistance to anthracnose, cercospora leaf spot and powdery mildew diseases.

“…The selected model is defined by (1)- (6). In this model the average error (root mean square) in time to flowering prediction is 11.6 days (λ = 50), the resource amount Y needed to flower is 40.27 and the coefficient threshold (1) where F n are climatic control functions and n (2)- (6) describe an added impact of n-th function on plants from different countries of origin.

Background Phenology data collected recently for about 300 accessions of Vigna radiata (mungbean) is an invaluable resource for investigation of impacts of climatic factors on plant development. Results We developed a new mathematical model that describes the dynamic control of time to flowering by daily values of maximal and minimal temperature, precipitation, day length and solar radiation. We obtained model parameters by adaptation to the available experimental data. The models were validated by cross-validation and used to demonstrate that the phenology of adaptive traits, like flowering time, is strongly predicted not only by local environmental factors but also by plant geographic origin and genotype. Conclusions Of local environmental factors maximal temperature appeared to be the most critical factor determining how faithfully the model describes the data. The models were applied to forecast time to flowering of accessions grown in Taiwan in future years 2020-2030.
