Abstract
Greengram [Vignaradiata(L.) Wilczek] is an economically important grain legume crop next to chickpea, pigeon pea and urad gram. Among the biotic factors, Mungbean Yellow Mosaic Virus (MYMV) is reported to be the most destructive viral diseases, which may reduce the seed quality as well as the yield losses up to 100 per cent. It is transmitted through whitefly (Bemisiatabaci) in a persistent manner throughout Asia, including India. A set of forty-two diverse mungbean genotypes were sown in two replications using a Randomized Block Desigh (RBD) during the summer season of 2015. The infector row method was adopted to evaluate a set of mungbean genotypes to know the difference in the level of resistance against MYMV infection under field condition during summer, 2015. Percent Disease Incidence (PDI) was calculated at 30 DAS and 50 DAS respectively. It varied from 2.18 to 64.77% and 5.38 to 76.87% at 30 DAS and 50 DAS respectively in summer, 2015. On the basis of disease severity recorded, the mungbean genotypes were classified in to five disease infection categories. Out of the forty-two mungbean genotypes, thirteen genotypes viz., Pusa 0672, IPM 205-7, HUM 8, KM 2245, IPM-2-03, ML 1464, KM 2241, PDM-139, TARM-1, HUM 26, Meha, HUM 16 and IPM 409-4 were found to be resistant and may provide the source of resistance against MYMV to develop mapping population for molecular breeding, development of molecular markers, QTL identification for MYMV resistance, as well as development of MYMV resistant varieties.
