Abstract: Mung bean yellow mosaic is a major destructive disease affecting blackgram productivity in India. It is transmitted by whitefly Bemisia tabaci. The present investigation was to identify resistant blackgram genotypes against MYMV at natural condition through field screening. Infector row method was followed to screen the genotypes. Screening was done with 120 blackgram genotypes during summer 2018. Genotypes which were found to be resistant (28) and moderately resistant (28) at summer 2018 were further screened during summer 2019. Genotypes viz., KKB 14034, KKB 14003, KKB 14004, KKB 14045, KKB 14051, KKB 14014, KKB 14009, KKB 14020, KKB 14038, KKB 14015, KKB 14001, KKB 14043, KKB 14042, KKB 14041, KKB 14053, KKB 14048, VBG 10010, VBG 10053, RU 1511, RU 1513, VBN 6 and VBN 4 exhibited resistance in both the years. These genotypes would be utilized as donors to develop MYMV resistant lines and can also be used for further artificial screening studies like agroinoculation, forced feeding method.
