تقدير الارتباطات بين الصفات و تحليل معامل المسار لصفات الحاصل و مكوناته في محصول الماش Vigna radiate L.

The experiment factorial was conducted at the research station of the Faculty of Agriculture (Al-sayeda) in Kirkuk Governorate for the autumn agricultural season (2017) to study genetic, environmental and phenotypic correlation between traits (number of flowering days 50%, plant height (cm), number of branches. plant-1, number of bacterial nodes, weight of dry matter / plant, leaf area cm2, leaf area index cm2, pod length(cm) number of pods.plant-1, number of seeds / pod, weight of 100 seeds /g, Seed yield /plant, biomass, seed yield kg / ha, harvest index, protein% and yield efficiency) using the randomized complete block design with three replicates correlation values of the yield and its components into direct and indirect effects the results showed a desirable high genetic correlation of the seed yield /plant with the number of days to a 50% flowering and the seed yield kg/ha to 0.987 and 0.965 respectively, while with seed yield kg / ha، to pod length(cm) number of flowering days 50%,1.563 and 1.044. While the highest phenotypic correlation is desirable for the seed yield /plant with the plant height and Seed yield /plant 1.666 and 1.492 respectively, while for seed yield kg/ha to 100 seed weight and seed yield /plant of 1.519 and 1.492.The analysis of the path coefficient analysis was the highest direct effect by use genetic correlation on the 100 seed weight of 1.03784, while the highest indirect effect phenotypic correlation on the number of pods.plant-1 and 100 seed weight 2380.85 and 480.64 respectively.
