Abstract

Afield experiment was conducted at the field farm located in Al – Mussiab project 30 km north of Babylon through two season fall of 2011 and spring of 2012 On season 2011 seeds were planted (Sy7, Dr-c-10, HS, Zp607,and Zp707) with tester (Al–Maha, Spanish hybrid and Sy1) was don. In spring 2012 for crosses and parents using R.C.B.D with three replication to evaluate and estimate some genetic parameters. The results of statistical analysis for these parents and their crosses were highly significant differences for all traits. Genetic analysis show superiority the inbred (Zp607) in gca for plant height , ear Length and no. of rows and leaves area, the hybrid Dr-c-10 X Al – Maha characterized by specific combining ability in all the studied characters specially in the total grain yield . σ2gca / σ2Sca were less than one for all inbred and tester traits. The traits controlled by over dominance where average dgree of dominance was more than if could be concluded the possibility of using superior inbreds or use selection for it to produce hybrids and synthetic varieties.
