In the present investigation, heterotic effects were studied over mid parent, better parent and standard check parent values for ten yield and yield attributing components in 7 different genotypes of black gram. High heterotic effects were observed for branches/plant, flowers/plant, pods/plant, seeds/pod,biological yield, seed yield. High heterotic response for seed yield per plant was mainly due to pods per plant and number of seeds per pod. Among 21 crosses, only six crosses viz., COBG 653 x Udid No.55, PKV U-15 x IPU 02–33, Udid No. 55 x PKV U-15, COBG 653 x PKV U-15, IPU 02–33 x KU 96-3 and KU 96-3 x KU 99–33 exhibited highly significant and maximum heterosis for better parent (BP) and economic heterosis (CP) for number of pods per plant, pod length, pod breadth, number of seeds per pod and seed yield per plant. These hybrids are, therefore, suggested to be utilized for developing high yielding black gram cultivars.
