Evaluation of Genotypes for Drought Stress Resistance in Soybean (Glycine max (L.) Merrill) Under Induced Water Stress

摘要

In present investigation under induced water stress in soybean (Glycine max. (L.) Merrill) investigated that, soybean genotypes viz., AMS-99-33, TAMS-98-21 and JS-335 was maintained better in stress environment for the RWC and total chlorophyll content resulting from better drought tolerance capacity. The genotype viz., AMS-99-33 (7.22), TAMS-98-21 (7.85) and JS-335 (7.95) recorded the less stomatal index in stress condition at 30 and 50 DAS showing its better drought tolerance capacity. The genotypeAMS-99-33 recorded highest RWC (52.44%) in stress condition followed by TAMS-98-21 (51.89% ) and JS-335 (51.10%). The genotype JS-335 recorded the highest drought intensity followed by TAMS-38 and TAMS-98-21. The study of different physiological parameters concluded that, the genotype JS-335 recorded the highest drought stress resistance for various drought stress parameters followed by the genotype TAMS-38 and TAMS-98-21.
