Author(s): Maniram, Ompal Singh, Raj Bahadur, Manoj Kumar and RK Yadav
Parameter viz., number of primary and secondary branches per plant, plant height, number of nodules, biomass per plant, CGR, RGR, days to maturity, total chlorophyll, nitrate reductase activity and protein content were studied at 55, 75 and 95 DAS whereas, biological yield, yield and yield components were studied at harvest the results revealed that genotype KWR-108, RSG-888 and KSJD-884 were drought tolerant and PG-5, K-850 and JG-74 were drought susceptible genotypes. The drought tolerance capacity of tolerant genotypes was associated with retention of high RWC, less membrane damage, high total chlorophyll content and higher osmotic potential under stress conditions. Drought tolerant varieties have less reduction in maintained NAR, RGR and CGR for longer duration. Regarding sink potential, the tolerant genotypes recorded less reduction in yield attributes like pods per plant, seeds per plant, 100-seed weight, straw yield, harvest index and grain yield under conditions of water stress over the susceptible genotypes.
