| Abstract | ||
| Filed experiment was carried out at the center of guiding and training agricultural Al-Mahnawia Babel / in south of baghdad during the autumn season 2010, 2011to evaluation the parents and it's hybrids that production by half diallel crosses select the superior hybrids. During full season 2010 the parents of maize was plant and flowering the half diallel crosses was done among the these eight parents (syn-1, syn-74 , inb-8 , inb-20 , inb-27 , pjo-25, pjo-46 , pjo-47) by using Graffing methods. The number of hybrids are 21 hybrid in the end of season at fall season 2011 a field comparison experiment was done according to R.C.B.D. The mean heterosis, gene action combining ability with its effects heritability and the average degree of dominance for all characters was studied. The biometric analysis variance was significant by (LSD) to comprised among treatment at 5% , the analysis revealed a high significant difference among the genotype for all study traits, this means that a large different among the parents. (4) parents was superior for flowing traits leaf areas number of row/ear, 36.70 cernals / row and 6.49 T/h sequentially (2467.75 , 16.75 , 36.70 , 16.41 ). But the hybrids (2x5) was superior by giving high average for the following traits : leaf area , number of rows/ear, grain yield (3143.25 , 18.40 , 9.50). While the heterosis of the hybrids (2x5) was superior by giving high heterosis for flowring traits: leaf area , number of rows/area , total gram yield , by giving (4681.81 ، 32.85 ، 20.24 and 176.56), the (7x8) hybrid was superior at A spiciphic combining ability by giving high for flowering traits ((leaf area , number of rows/ear and number cernals / row). While the ratio between gca / sca larger than one however the bread sense heritability was high for all traits study, yet narrow sense heritability gave low value, and the average degree of dominance was more than one for al study traits. | ||
