| Abstract | ||
| Seven inbred lines of Maize: (OH, ZP301, UN44052, SH, IK-58, IK-8, and R-153 ) were used in this study a half diallel Cross at spring 2014 in one farmers field in Baiji province . In evaluation season the genotypes (parents and single crosses beside to the commercial Variety (Moring)were planted. in shiwan station of Agricultural Administration of Kirkuk City at spring season of 2015,some traits were studied are: (number of days to 50% male and Female flowering ,plant height, main ear height, leaf area , number the leaves above main ear, number of the ears, length of the ear, ear diameter, number of rows in the ear, number of the kernels in the one row, number of the kernels in the ear ,weight of 300 grains and single plant yield ).Show that hybrid (6x5) was the earliest in male and female flowering with (62.566 and 65.583) days respectively , the superiority of hybrid (4x1)plant height and number of the ears and took (182.893cm)( 1.656cm) respectively, and the superiority of hybrid(4x2) in the main ear height(78.635cm) , Hybrid (5x3) in my recipe number of leaves above the main are length of the ea (6.550) (21.083) respectively, Hybrid (2x1) recipe for a number greade beans and ear and holds the individual plant and at a rate of (43.840grain) (762.78grain) (190.587g) respectively, Cluster analysis for the parents was showed that there are two main groups in the cluster analysis, The first group included four genotypes is (1,2,7 and4) second group consisted of two groups ,The first group consists two installation (6 and 3) and secondary group included the installation of hereditare one (5).The high value of genetic diveraty was between two parents (IK8) and (OH40) (11870.75) and the least value of genetic diversity was between two parents (IK8) and (IK58) (260.43),Parents take advantage of the divergent genetically improve the local varieties through the transfer of genes in one of the superior education methods can. | ||
