Abstract:
Four lines and ten testers were crossed in Line x Tester mating design and their resultant 40 hybrids were evaluated coupled with standard checks i.e., CSH-25 (for earliness) and CSH-35 (for grain yield) for grain yield and its associated components to study heterosis and combining ability. The current investigation revealed that total fifteen crosses exhibited positive and significant standard heterosis for grain yield per plant. Out of these fifteen crosses, total eleven hybrids exhibited positive significant SCA effects along with positive significant standard heterosis for grain yield per plant. The hybrid AKMS 14 A x AKR 524 exhibited highest significant positive SCA effects (17.43**) and positive significant standard heterosis (18.53**) for grain yield per plant along with the component traits like panicle weight, panicle breadth, number of grains per panicle, fodder yield per plant, 1000 grain weight and grain hardness. Hence, these eleven crosses need to be tested in multilocation and multisession evaluation trial to find out the stable cross combinations for their further commercial exploitation in kharif sorghum
