Evaluation of blackgram [Vigna mungo (L.) Hepper] cultures against yellow mosaic virus under natural conditions

Out of 20 blackgram germplasm lines evaluated against yellow mosaic virus under natural conditions, the lines IC 56051 and IC 59702 were found to be immune to the disease recording highest seed yield of 3.51 g/plant. These lines may be utilized either directly or indirectly in breeding programme for developing varieties resistant to yellow mosaic virus coupled with yield.
