Abstract

This experiment was conducted on fourteen genotypes from two and three maturity group of SOYBEAN as Baj-Maj, M9, Hy-1, L17, Union, Bonus, Williams,Hack, Clark, Halcor, Flanklin, LD9, Steel, Elgine under two normal and DROUGHT STRESS condition. The stress was induced from flowering stage as 7 versus 14 days irrigation. The results showed significant correlation between one hundred grain weight, inter nod, plant height with grain yield at 1% level under normal condition. The highest correlation belonged to plant height and inter nod. There were positive and significant correlation between plant height and number of grain per plant and one hundred grain weight at 1% level too. On the other hand the positive and highest significant correlations were between plant height, days to maturity, inter nod with grain yield under DROUGHT STRESS at 1% level. There were positive and significant correlations between plant height and other studied traits such as inter nod, number of pods per plant, number of grain per plant, average leaf area, one hundred grain weight and grain yield at 1% level. In STEP WISE REGRESSION analysis under normal condition, four traits including plant height, average leaf area, number of sub branches and number of pods per plant were inserted to statistical model. They supported 69.6% of variation of dependent variable. In PATH ANALYSIS the highest direct and final effect on grain yield belonged to plant height. The results of STEP WISE REGRESSION analysis under DROUGHT STRESS, three traits including plant height, days to maturity and one hundred grain weight were inserted to statistical model. They supported 64.1% of variation of dependent variable. In PATH ANALYSIS the highest direct and final effect on grain yield belonged to plant height.
