الملخص الإنجليزي

Field experiments were carried out during 2011-2012 to study combining ability and gene action, to identify the best parents and crosses general and specific combining ability and evaluate F1 hybrid, by using seven genotype (Aras, Noor, Sham-6, Aiala, as line and Maxibak, Tamoz-2 and Adnanea as tester), 12 F1 hybrids evaluated at the research farm of the agriculture Duhok university.

According to the results, the ratios of GCA:SCA variance were lower than one for all the traits except plant height and grains yield plant- 1.

The additive gene actions were significant for all the traits except spike length, and hence the ratios of GCA/SCA variances for these characters were lower than one.

The crosses Aras x Adnanea, Noor x Maxibak, and Noor x Adnaneaand Sham-6xAdnanea might be considered as promising hybrid combinations in terms of most traits
