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.
