Abstract
Ten inbred line of corn (Zea mays L.) lever used and entered in crosses as a factorial mating system by lines (Agr-183, Zp505, Zp670 and Zp-197)as male parents (m) and lines (Ik-58 , Cml494 , Pio-46 ,H-s , Pio-47and Pio-25) as female parents . The lines and its single crosses were planted in Yiaichi region in Kirkuk governorate using (R.C.B.D) with three replicates in two seasons , spring and autumn 2015 , the results of statistical analysis showed significant differences in the means of studied traits for the parents and the crosses , the crosses were distinguished which entered as apparent Pio-25 in most studied traits , the cross (Pio-25×Zp-197) was gave high yield of grains (186.25 gm/plant) and surpassed in giving the most effect in general combining ability gave (32.25 gm) and also higher specific combining ability . The additive variance values were showed that controlled in trits number of ears, number of the rows in the car and number of kernels in the row. reflected on the increase of heritability values in broad and narrow sense , and genetic expected advanced as a percentage for these traits , the degree of dominance was less than one , while the values of dominance variance were controlled in genetic kerenles yield , the degree of dominance was more than one , which reflected on the genetic expected advance which was
