Abstract : Greengram and blackgram are most important species of Vigna group of grain legumes. Among these species mungbean [Vigna radiata (L.) Wilczek] and urdbean [Vigna mungo (L.) Heppar] are the major pulse crops of Indian subcontinents. One of the very significant problem with pulse crops is Mungbean Yellow Mosaic Virus. Therefore, inheritance of resistance to mungbean yellow mosaic virus was studied in six intraspecific and four interspecific crosses of Vigna involving three resistant varieties of mungbean namely HUM16, Samrat, TMV37 and three resistant varieties of urdbean namely PU31, Uttara and Sekhar. One susceptible genotype of each was LGG450 and Barabanki of mungbean and urdbean respectively. The parents F1, F2, BC1 & BC2 generation were grown with their respective susceptible genotype. Susceptibility of MYMV was dominant over resistance in the F1 generation of all the crosses. Observations on disease incidence of F2, BC1 and BC2 generation indicated that pair of recessive genes showed resistance against MYMV in each of the crosses.
