Online published on 29 April, 2014. Abstract Blackgram is a one of the major pulse crops in India. The Yellow Mosaic disease (YMD) caused by Mungbean Yellow Mosaic Virus (MYMV) is one of the most destructive diseases of blackgram growing areas of Southern India. The inheritance of resistance to YMD was examined in F1, F2, F3 and RIL population of inter sub-specific cross of blackgram involving resistant cultivar ‘VBN (Bg) 4’ (Vigna mungo) and susceptible accession of Vigna mungo var. silvestris 22/2, a wild progenitor of blackgram. The results of genetic analysis showed that a single dominant gene controls the YMD resistance in blackgram cultivar ‘VBN (Bg) 4’. The resistant lines identified in the present study could be used in the development of YMD resistant varieties in blackgram.
