A field experiment was conducted to evaluate the performance of twenty five blackgram genotypes under naturally epidemic conditions to leaf curl disease. The experiment was under taken during the late rabi 2018-19 and 2019-20 in a randomized block design replicated thrice. The investigation has focused on the study of variation in the dry matter production efficiency of the genotypes as influenced by leaf curl disease infection. The results obtained indicated that the leaf curl disease has severely affected the growth and dry matter partitioning efficiency of all the blackgram genotypes tested. The genotypes that show resistance to leaf curl disease showed less reduction dry weights. Leaf dry weight, pod dry weight and total dry matter showed a highly significant negative correlation with leaf curl disease at 60 DAS and maturity. The resistant genotype TU 40 showed higher partitioning efficiency and pod dry weights.
