Abstract
This experiment was carried out in the Laylan region , (15) km away from the center of Kirkuk Governorate during the winter planting season (2018-2019) for using six varities as males parent (1) Milan ,(2) Site Mall ,(3)hthab ,(4) clack ,(5)Cowes and(6)Florca ) and four varities as Female parents (7) Sham 6 ,(8) Abu Ghraib 3 ,(9)Abaa 99 ,(10) Ausis and twenty four hybrids adopt on the varities to the first-generation ( F1 ) and second-generation ( F2 ) . The experiment was carried out by Randomized Complete Block Design ( R.C.B.D ) with three replicates in two separate experiments , including The first experience parents and hybridized for the ( F1 ) and the second experience parents and hybridized to the ( F2 ), with the aim of assessing the genetic behavior of the first and second generation in the bread wheat (TriticumaestivumL.), using
Factorial Mating and estimating the General and Specific Combining Ability, Gene Action, and studied the characteristics, yield per plant, Protein ratio and Glutein ratio , The results showed high and desirable effects of the General Combining Ability of the father (Florca) in an experiment evaluating hybrids of the first and second generation and for all traits, while the hybrid (Ausis × Site Mall) showed high and desirable effects of the Specific Combining Ability for , yield per plant and Glutein ratio in first generation and all studied traits were under the control of the DominanceGene Action in my experience evaluates first- and second-generation hybrids
