Peeta Gopi, Satyanarayana A, Rama Krishna A and Sambasiva Rao KRS

The experiment carried out at the R&D Farm, NRI Agritech and ANU, Nagarjuna Nagar, Guntur. To identify genetic sources of resistance to yellow mosaic virus (YMV) in blackgram vigna mungo (L), 49 germplasm lines are collected from different geographical regions were evaluated under field conditions during period rabi season November 2014 - February 2015, 2 entries exhibited resistance(R) reaction with rating of 1.0 to 2.0. Six genotypes feel in the category of moderately resistant (MR) with rating scale of 2.1 to 4.0, three were moderately susceptible (MS) with rating of 4.1 to 5.0; two genotypes were susceptible (S) with rating of 5.1 to 7; and 35 genotypes were highly susceptible (HS) with rating 7.1 to 9. This study reveals new source of resistance for use breeding programme aimed at developing YMV resistant varieties.
