| Abstract | ||
| This study target to study the correlations genetic and phenotypic and environmental for yield characters and some of its components, including (number of active tillers, spike length, , the intensity spikes, the number of grains spike, and weight of 1000 grains) as well as divided effects of direct and indirect for some yield characters components, where used five lines of wheat for Randomized Complete Block Design with three replicates. The results showed number of tiller actives in first season was high genetic correlation to grain yield 1.088 negative with spike length -1.684 and spike length and spike length with the number of grains spike 1.599, and negative for the weight of 1000 grains -2.111, while phenotypic correlation was high significant negative for spike length with grain yield -1.042 and the weight of 1000 grains with grain yield -0.865.The second season was high genetic correlation negative for number of active tillers with spike length -0.821 and the number of grains spike -2.898 and positive with the weight of 1000 grains and spike length with the intensity spikes 2.103 and negative with the weight of 1000 grains and the number of grains spike -1.722 with grain yield were -2.094,while for the weight of 1000 grains with grain yield was genetic correlation positive 0.926, whereas phenotypic correlation for number of active tillers with the weight of 1000 grains were 1.080 for spike length and for spike length with number of tiller actives were -1.892. The analysis of path coefficient for correlations genetic in first season. Higer direct effects had shown 0.8908 for number of active of active tillers, where as in second season high effect direct 2.1891 for the weight of 1000 grains and phenotypic correlation effect direct was in number of active tillers were 0.6677 for number of active tillers too. | ||
