Abstract
The full diallel cross of six it inbreds line of maize in the Autumn season (2016) was carried out in the college of Agriculture, University of Anbar, alternative site Abu Ghraib Baghdad. In the spring season (2017) west of Iraq. The experiment included sowing the seeds of inbreds and hybrids resulting from crossing, which included 30 hybrid and reverse hybrids. using the design of the complete randomized design (RCBD) and three replicates. The aim of the study was to evaluate the behavior of the breeds and their hybrid and reverse axes by traditional and morphological methods. The results of the study showed the following: The genotypes differed significantly among all studied traits. The phenotypic performance of paternal strains 1 and 3 were distinct after they obtained the highest values of grain status. The superiority of these two strains was reflected in the cross-diallel (1x3) resulting from their crossing when given the highest grain yield. The results of the genetic analysis in the first method and the fixed model of the Griffing analysis indicated a greater importance for the non-additive gene in the inheritance of most of the studied traits, while the additional genetic act was more effective in inheriting the leaf area trait in the direction of reverse infarction. Most hybrid and reverse crosses gave significant values to the hybrid force in most studied traits.The results of the full diallel cross analysis indicated that the average squares of viability of the general and specific combining ability and reverse crosses were highly significant for most studied traits. This showed the importance of both the additive and non-additive function in controlling the inheritance of traits. Parents 1 and 3 showed an significant effect of their general ability in several traits, most notably the grain yield, and some of the hybrids showed desirable effect of their own union of grain status and a number of other traits. The ratio of the variation of the effect of the union to the general in the cross breed and reverse crosses was less than the correct one for all studied traits except for the paper area in the opposite direction. The percentage of inheritance was high values in the broad sense and low in the narrow concept of most of the traits studied in cross breeding and reverse.
