The inheritance of resistance to mungbean yellow mosaic virus (MYMV) was studied in crosses involving three resistant lines, BR til, Sel 1, and NP 21, and a susceptible line, UL 2. The parents, F1, F2 and F3 generations were grown along with UL 2 spreader rows after every 5th row. Artificial inoculation with MYMV was done through the insect vector, whitefly (Bemisia tabaci). Susceptibility to MYMV was dominant over resistance in the F1 generation of all the crosses including the reciprocals. The F2 and F3 observations indicated that two recessive genes are involved in imparting resistance against MYMV. No maternal effect was observed.
