“…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.

Mining legume germplasm for genetic gains: An Indian perspective

Legumes play a significant role in food and nutritional security and contribute to environmental sustainability. Although legumes are highly beneficial crops, it has not yet been possible to enhance their yield and production to a satisfactory level. Amid a rising population and low yield levels, per capita average legume consumption in India has fallen by 71% over the last 50 years, and this has led to protein-related malnutrition in a large segment of the Indian population, especially women and children. Several factors have hindered attempts to achieve yield enhancement in grain legumes, including biotic and abiotic pressures, a lack of good ideotypes, less amenability to mechanization, poorer responsiveness to fertilizer input, and a poor genetic base. Therefore, there is a need to mine the approximately 0.4 million ex situ collections of legumes that are being conserved in gene banks globally for identification of ideal donors for various traits. The Indian National Gene Bank conserves over 63,000 accessions of legumes belonging to 61 species. Recent initiatives have been undertaken in consortia mode with the aim of unlocking the genetic potential of ex situ collections and conducting large-scale germplasm characterization and evaluation analyses. We assume that large-scale phenotyping integrated with omics-based science will aid the identification of target traits and their use to enhance genetic gains. Additionally, in cases where the genetic base of major legumes is narrow, wild relatives have been evaluated, and these are being exploited through pre-breeding. Thus far, >200 accessions of various legumes have been registered as unique donors for various traits of interest.

“…Green gram, Vigna radiata, a tropical pulse crop largely grown under semi-arid and subtropical environment is very sensitive to low temperature regimes. Though green gram has a multifarious advantage, sensitivity to chilling stress can largely limit its productivity [6]. Low temperatures can hamper the seed germination [7] and delay plant growth and development leading to variability in crop maturation and reproductive ability of plants [8].…”

Aims: Morphological characterization and germination based screening for cold stress response of Vigna radiata, was performed to identify the cold resistant genotypes. Methodology: Augmented design experiment was performed to characterize 204 mungbean genotypes under field condition based on 24 DUS characterization. A germination-based screening at 10°C was performed in a total of 204 germplasms in a plant growth chamber to identify the cold responsive genotypes. Seeds were soaked in water for 6h in the dark under normal temperature and imposed cold stress (100C) for 2, 4, 6, 8 days and further transferred to control temperature (220C) for recovery. Results: On the basis of the 24 DUS characterizations of 204 mungbean genotypes are classified into three major clusters. Highest number of genotypes in cluster I (113 genotypes), followed by 81 genotypes in cluster II and least number (10) of genotypes in cluster III. Based on cold stress study and biplot analysis showed that germination percentage, germination rate index, Timson’s index, mean germination time and coefficient of velocity of germination to be more influential and categorized into three groups having 11 genotypes are resistant, 135 genotypes are susceptible, and 58 genotypes are intermediate. Biochemical analysis showed that the tolerant genotype having increased chlorophyll, carotenoid and MDA content and oxidative enzyme activity as compared with susceptible and intermediate genotypes under cold stress. Conclusion: The present study identified 11 genotypes having cold resistant and may be used for breeding program.
