Genetic analysis for grain yield and quality parameters in durum wheat (Triticum durum Desf.) under late sown condition

摘要

Combining ability analysis was carried out in 8 x 8 parental diallel progenies for grain yield and its component traits in durum wheat. General combining ability and specific combining ability variances were highly significant for all the characters suggesting importance of both additive as well as non-additive type of gene action in the inheritance of characters. The magnitude of the non-additive genetic variance was higher than additive variance for all the characters except plant height and lengthof main spike. The parent BAWAJI was good general combiner for all the characters except plant height. For grain yield per plant, the crosses GW-02-51 x VDW-99-176, GW 1239 x GW 1189 and GW-02-51 x RD-1009 recorded the highest sea effects. The cross GW-1139 x GW-1240 expressed highest sea effects for grain protein and hectoliter weight.
