Wilczek] is one of the most important pulse crops in India. In the traditional vegetarian diet of Indian population, pulses occupy second place next to cereals and is the main source of protein, ranking after chickpea and pigeonpea. It is an important short duration grain legume which can be grown in varied environments, across International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 05 (2018) Journal homepage: http://www.ijcmas.com Mungbean [Vigna radiata (L.) Wilczek] is an important short duration grain legume which is grown in different parts of the country, for grain and green manure. It is an outstanding source of easily digestible proteins with low flatulence, which balances the staple rice diet in Asia. Mungbean yellow mosaic disease (MYMD) caused by whitefly ( Bemisia tabaci) transmitted mungbean yellow mosaic virus (MYMV) is an important constraint of mungbean in India. Thirty five Indian mungbean genotypes were evaluated to identify the source of resistance against MYMV during kharif-2013. The per cent disease incidence (PDI) of MYMV among 35 mungbean genotypes was worked out up to ninth week after sowing and it varied from 0 to 84.96%. At maturity stage of crop (ninth week after sowing), mean PDI was 27.09% and mean disease severity index (DSI) was 2.73. Out of 35 mungbean genotypes, five were found highly resistant, six were resistant and seven were moderately resistant. While, eight genotypes were found moderately susceptible, seven were susceptible and two were highly susceptible. Five genotypes namely, Meha, Bada Mung 7, KM 2245, IPM 0205-7 and IPM 02-3 found highly resistant during present investigation which can be used for the development of mapping population for the development of MYMV resistant varieties.
