Abstract:

Six cytoplasmic male sterile lines (CGMS) and eleven testers were crossed in line x tester fashion and the resultant 66 hybrids were evaluated along with the checks (CSH 35) for grain yield per plant and fodder yield per plant through combining ability and heterosis analysis. The outcome of current investigation revealed that two dual purpose cross combinations was identified (ICS 751A x AKR 530 and ICS 733 A x AKR 529) having positive significant sca effects for grain yield and fodder yield per plant (22.67** and 26.44** respectively) as well as positive significant standard heterosis for both grain yield per plant (44.27 % and 29.16 %) and fodder yield per plant (29.16 %). Likewise, four promising cross combinations (ICS 279 A x AKR 528, AKMS 89 A x AKR 492-1, AKMS 89 A x AKR 527, and ICS 733 A x AKR 530) recognized for grain yield per plant on the basis of significant positive sca effect (13.87**, 9.20**, 8.93**, 7.37** respectively) and significant positive standard heterosis (22.79%, 21.57%, 20.66%, and 21.31%). With respect to fodder yield per plant, three promising crosses (AKMS 90A x AKR 527, ICS 279 A x AKR 526 and AKMS 89 A x AKR 523) had significant positive sca effect (86.62**, 11.49**, 27.97** respectively) along with significant positive standard heterosis over the check CSH-35 (69.72 %, 23.02 % and 14.25 % respectively).
