In the present study, 20 diverse male parents (tester) and 5 female parents (male sterile lines) were used to develop 100 crosses in line x tester design. The magnitude of heterosis over mid parent value (H), better parent (HB) and hybrid check (SH) for grain yield per plant ranged from -40.92% to 37.22%, -46.92% to 34.05% and -29% to 49.13%, respectively in data pooled over three environments, while it were ranged from -54.37% to 57.29%, -58.77% to 48.60% and -41.97% to 64.53%, respectively for dry fodder yield per plant. Out of hundred crosses, ten and eleven crosses in pooled data showed significant positive heterosis over hybrid check (SH) for grain yield per plant and dry fodder yield per plant, respectively. Out of these crosses, ICMA-843-22 x RIB-3135-18 (22.37) and ICMA-94111 x RIB- 3135-18 (19.99) found best cross on per se performance for grain yield and also showed significant positive heterosis over standard check (RHB-177) on pooled basis for grain yield (49.13 and 33.27), dry fodder yield per plant (46.42 and 23.39) and earliness of 50% flowering (-10.29 and -9.29), respectively, thus those crosses could be tested in multi-location programme to identify commercial hybrid.
