ABSTRACT

An investigation was undertaken to elucidate information on the effects of water stress on yield and yield attributes of soybean {Glycine max (L.) Merrill} at pod development stage. The soybean accessions viz., JS92-22-A, IC18596, IC9311, IC216380, IC110399JS (SH) 99-02, IC16040, IC16040 and VLS53 showed better performance for morphological traits under water stress condition. Among the morphological traits studied, days to maturity showed the maximum reduction (94%) followed by harvest index (69%) and seed yield per plant (55%), while plant height was recorded the lowest reduction of 16% at pod development stage under water stress condition. The genotype VLS53 showed the highest drought tolerance index for seed yield.
