Abstract:

The present pot experiment was performed to assess the effect of post anthesis drought stress on physiological and biochemical parameters of soybean and to identify drought tolerant genotypes which can be used further in drought breeding programme. A set of 30 soybean genotypes were evaluated at post anthesis stage under stress and normal condition both to identify the tolerant genotype. Seven physiological parameters namely leaf area index, leaf area duration, crop growth rate, relative growth rate, net assimilation rate, relative water content and soil moisture content by tensiometer and seven biochemical parameter namely membrane stability index, total chlorophyll content, total carotenoid content, lipid peroxidation, proline content, SPAD chlorophyll meter reading (SCMR) and drought susceptibility index were calculated for screening the genotypes. On the basis of yield reduction percentage and drought susceptibility index the identified drought tolerant eight genotypes were JS 20-29, JS 20-98, JS 97-52, JS 21-17, JS 21-73, DAVIS, TGX 852-3D and CAT 2082.
