Abstract

A 6 x 6 half diallel was conducted at the Experimental Farm, Faculty of Technology and Development, Zagazig University, Egypt., during the two successive growing seasons 2013/2014 and 2014/2015. The fifteen crosses along with their parental genotypes (Gemmeiza 11 (P1), Sids 12 (P2), Giza 168 (P3), Sahel 1 (P4), Line 18 (P5) and Line 26 (P6)), were evaluated to estimate gene action effects for grain yield and its components.Mean performance of wheat parental genotypes and their F1 crosses for grain yield and its components exhibited significant differences for all studied characters. The parental genotypes Gemmeiza 11, Sahel 1 and Giza 168 gave the highest productivity for grain yield/fad. Regarding the F1 crosses (P3×P5), (P2×P3), (P1×P2) and (P1×P6), they gave the highest productivity for grain yield/fad. On the other hand, the parental genotypes Line 18 (P5) and Line 26 (P6) and F1 crosses (P1 × P3) and (P2 × P4) exhibited the lowest values in grain yield/fad.  
The results showed thatsignificant values of additive (D) and dominance (H1 and H2) for all characters, except 1000-grain weight and grain yield/fad., revealing the importance of both additive and non-additive gene action in the inheritance.
The dominance genetic effects (H1 and H2) were more than the additive gene effects (D), fornumber of spikes/plant,spike grain weight (gm.), grain yield/plantand grain yield/fad., showing that these characters were controlled by dominance gene action and could be improved through hybrid breeding method. But the additive gene effects (D) were more than non-additive gene effects (H1 and H2) for number of spikelets/spike, number of grains/spike and 1000-grain weight, showing that these characters is controlled by additive gene action in these characters. Narrow sense heritability estimates were high for number of spikelets/spike (61.256 %) and number of grains/spike (56.584 %).
