Mungbean Yellow Mosaic Virus (MYMV) disease is one of the most devastating diseases of greengram causing 85 – 100 per cent yield loss and transmitted by the white fly, Bemisia tabaci. This has become increasingly serious because of the lack of resistance in the existing cultivars. Ten greengram genotypes were screened for MYMV disease resistance at hotspot of National Pulses Research Centre, Vamban during kharif season. Among them, SML 1815, MH 421 showed resistant reaction whereas, VBN (Gg) 3, VBN (Gg) 2, LGG 460, RMG 10-28 and TM 96-2 showed susceptible reaction. Three crosses were made between resistant and susceptible genotypes. The three F2 populations were sown along with blackgram CO5 as infector row for evaluation against MYMV resistance. The F2 population segregated in the ratio of 15R:1S and 13R:3S, suggesting the involvement of two dominant genes in imparting resistance against MYMV disease.
