Abstract<\/strong><\/p>\n\n\n\n

A factorial\nmating was carried out between male parents (OH(1)<\/sub>, ZP-31(2)<\/sub>,\nUN440(3)<\/sub>, INbread12(4)<\/sub> and ZP-607(5)<\/sub>) and female\nparents (SH(6)<\/sub>, IK-58(7)<\/sub>, IK-8(8)<\/sub> and R-153(9)<\/sub>).\nIt had been done during spring 2014 at a farm in Baiji district. Parents and\ntheir hybrids had been evaluated at Shwan Research Station, Directorate of Agriculture\nin Kirkuk in autumn 2015 to figure out parents general combining ability (GCA),\nhybrids specific combining ability (SCA) and dominant gene action for number of\ndays till male and female flowering, plant height, leaf area, number of rows\nper ear, number of grains per row, 100 grain weight and single plant yield.\nResults showed a significant genetic difference among the genotypes in most of\nthe characteristics except number of rows per ear for male parents. The male\nparents (INbread12(4)<\/sub> and ZP-607(7)<\/sub>)weresignificantly combined positively for plant height and leaf area in\nINbread12(4) <\/sub>and 100 grain and yield for ZP-607(7)<\/sub>. The\nsame positive direction was obtained in female parents (IK-8(8)<\/sub> and\nR-153(9)<\/sub>) for number of days till female flowering, number of rows per\near and yield for IK-8(8)<\/sub>, and leaf area, number of rows per ear,\nnumber of grains per row and yield for R-153(9)<\/sub>. Hybridssignificantly\ncombined in a desired direction as well. For example, (OH X R-153), (INbread12 R-153X) and (ZP-607 X IK-58) combined in growth and yield characteristics.\nThe components ratio of (GCA) to (SCA) was less than one, and the dominance\nvariance was more than the additive variance. This was reflected on the broad\nsense heritability which was high, and on the\nnarrow sense heritability which was low. Finally, it is possible to prognosticate\nthat studied characteristics were controlled by the dominant gene action, and can\nbe selected as promising\nhybrids and avoiding the selection in the early generations.<\/p>\n\n\n\n
