Thirty-two elite true-breeding lines of a black gram (HPU 27) x green gram (PIMS 3) cross alongwith checks were evaluated in a randomized block design to study the nature of variation with respect to seed yield and 14 other traits. Analysis of variance revealed significant genotypic Differences for all the traits. Phenotypic and genotypic coefficiens of variation were high for seed yield/plant, biological yield/plant. clusters/plant. pods/plant. 100-seed weight, seed crushing hardness and per cent sulphur. Heritability estimates were high (>50%) for 100-seed weight, protein content, pod length seeds/pod and seed crushing hardness. The recombinant derivatives, MM 14, MM 24, MM 30 and MM 31 surpassed the parent(s) for seed yield and some of the other traits studied.
