摘要

Combining ability analysis was carried out in a 8 x 8 diallel cross of bread wheat to study grain yield and its component traits, excluding reciprocals, during the rabi season of 2008-09. Both additive and non-additive types of gene action played an important role in the inheritance of characters. The ratio of gca (general combining ability) to sca (specific combining ability) genetic variance for all characters indicated that the non-additive type of gene action was predominant in the expression of all traits i.e. plant height, number of effective tillers, length of main spike, spikelets per spike, grains per spike, 1000-grain wt., grain yield per plant, protein content, hectolitre wt., harvest index and sedimentation value. Parental lines GW 496, GW 397 and VA 06-15 were good general combiners for grain yield and other yield components. GW 404 was a good general combiner for grain yield per plant, 1000-grain wt., grain protein content and sedimentation value. The crosses GW 273 x GW 496, GW 392 x GW 273 and VA 06-15 x GW 322 recorded the highest sca effects and involved average x good, poor x average and good x poor gca parents. The cross VA-06-15 x GW 404 for grain protein content and the cross GW 392 x GW 397 for sedimentation value expressed highest sca effects.
