Abstract
One of the most devastating diseases affecting blackgram productivity in India is mung bean yellow mosaic. It is transmitted by whitefly (Bemisia tabaci). The current investigation was carried out to identify the blackgram genotypes resistant against the Mung bean yellow Mosaic virus (MYMV) through field screening at natural condition. The genotypes were screened using the infector row method. Twelve blackgram genotypes namely VBN-2, VBN-3, VBN-5, VBN-6, VBN-7 VBN-8, VBN-9 VBN-10, VBN-11, ADT-5, ADT-6 and CO-5 were used for screening during summer 2022. The genotypes viz., VBN-6, VBN-10 and VBN-11 were found to be resistant and moderately resistant viz., VBN-4, VBN-5, VBN-7, and VBN-8. It implies that utilization of these genotypes as YMV resistance donors for results in the production of high yielding MYMV resistant varieties through backcrossing or marker assisted backcrossing by introgression of the genes to agronomically potential genotypes that were susceptible to MYMV.
