Abstract

In order to compare of inheritance, combining ability and genes action in the genetic control of 1000-seed weight, harvest index, biological yield and seed yield of BREAD WHEAT cultivars, a study was conducted on eight cultivars using method 2 in fixed model of Griffing. Parents and crosses (36 treatments) were planted in randomized complete block design with three replications. Analysis of variance showed highly significant difference between treatments for all the traits. GCA and SCA mean of squares were highly significant for all the traits that designated importance of additive gene effects in inheritance of traits studied. The GCA/SCA ratio was significant for 1000-seed weight, harvest index and biological yield that reveal a greater portion of additive gene effects in genetic control of these. The GCA/SCA ratio is non-significant for seed yield that emphasizes the great importance of non-additive gene effects for this trait. In conclusion, genetic improvement of 100-seed weight, harvest index and biological yield is possible at early generations by selecting from the best crosses, while selection for seed yield is better that delayed until advanced generations and increase of it's HERITABILITY.
