Abstract

Water deficit can reduce seed yield in development stages of SOYBEAN plant. Tolerance to drought conditions in SOYBEAN depends on planting date. Maturity group of cultivars, time and duration of drought conditions. To evaluate the response of 25 genotypes of SOYBEAN to DROUGHT STRESS during reproductive developmental stage, two experiments were conducted using a 5x5 lattice design under stress and non-stress conditions. Results of analysis of variance showed- significant differences among cultivars for most of agronomic traits in both stress and non-stress conditions. Significant differences were found among cultivars for seed yield only in stress conditions, Williams and Probest cultivars had the maximum and minimum seed yield content respectively (2350.6 and 1048-.1kg/ha). The highest damage due to DROUGHT STRESS was found on branch hollow pod (-57.53%) and DROUGHT STRESS decreased the seed yield about (37.70%). In non-stress conditions, the majority of traits had significant CORRELATION.with seed yield (r=0.318) whereas in stress conditions, only number of branch seed and 100-seed weight had significant CORRELATION.with above-mentioned trait (r = -0.344). Based on the results of traits CORRELATION., step wise regression and path analysis in non-stress condition, harvest index, number of plant pods, the distance of first pod trom earth surface, blooming duration branch seed weight, and in stress conditions, the number of days until end of blooming seems to be desirable characters in selectionof cultivarswith high seed yield.
