Abstract

Current study was aimed to study the general combining ability (GCA) and specific combing ability (SCA) of 32 wheat hybrids and estimation of average heterosis, heterobeltiosis and standard heterosis. 8 Testers viz., AKAW 4630, AKAW 4739, AKAW 4731, AKAW 4498, AKAW 4800, AKAW 4730, AKAW 5077, AKAW 4924 along with the standard check HI 1418 were crossed with 4 lines viz., AKAW 3717, AKAW 2865, AKAW 2956, HI 1418 and 32 hybrids were developed which were evaluated in randomized block design during rabi 2018-2019. Among various tested lines only AKAW 3717 recorded positive and significant gca effects while among testers AKAW 4630, AKAW 4731, AKAW 4730 have positive and significant gca effects for seed yield and other yield contributing traits. The line HI 1418 and tester AKAW 4731 was the best combiner for days to maturity and other yield contributing traits. The line AKAW 2865 and the tester AKAW 4630 was the best combiner for grain weight per spike other yield contributing traits. Similarly, positive significant sca effect was exhibited by AKAW 3717 x AKAW 4731 (15.47) followed by AKAW 3717 x AKAW 4730 (14.09) for seed yield. Improvement methods which exploit both additive and non-additive gene effects could be useful for the characters included in the present study.
