Abstract:

Combining ability analysis was done in Line X Tester mating design by using 7 lines, 3 testers and 21 F1’s in a randomized block design with two replications during 2013-14 in sowing under water stress and non-stress environments. The analysis of genetic components revealed that both additive as well as non-additive components were prevalent for the control of grain yield and its components under both water stress and non-stress environments except spike length in under stress environment. The combining ability effects revealed that parent DL 803-3 was identified as good general combiners for grain yield under both water stress and non-stress environments and GW190 and GW 173 for grain yield under stress environment. The significant specific good combing cross ‘GW 322 X GW 173’ having one promising parent for grain yield under stress condition would be advanced through simple / recurrent selection in segregating generations. Most of the good specific combinations for various traits involved parents with high X low or low X low or low X high GCA effects. These genotypes may be used in breeding programs targeting high potential under drought stress. These parents may be used for varietal improvement through the simple / recurrent selection in segregating generations to increase in yield potential of wheat. This may lead in the fixation of both additive and non-additive components while making improvement in grain yield and its attributes.
