Thirty genotypes of mungbean (Vigna radiata L. Wilczek) of diverse genetic origin were screened for salt tolerance with ESP levels of 20, 30 and 40 along with control in earthen pots during summer, 2018 in Completely Randomized Design (CRD) with 3 replications. The observations were recorded for grain yield and its contributing traits number of pods/plant, pod length, number of seeds/pod and 100-seed weight. The investigated genotypes exhibited significantly variable response towards salt stress. Salt stress along with high-temperature stress-induced osmotic stress severely limiting the yield contributing traits. Genotypes KM 2241, IPM 02-3, Pusa Vishal and EC 88 maintained superiorly at all the levels of ESP for almost all the traits and there was marginal reduction with progressively increasing level of ESP indicated their efficient adaptability under salt stress environment and can be considered as salt tolerant. Genotypes SML 668, Jalgaon, I-51, IPM 99-125 and I10 showed resistance/tolerance with respect to all the traits up to 30 ESP. The above-said genotypes seem to have better resistance/tolerance to salt stress and can be used as source of resistant genes which can be introgressed in salt-sensitive mungbean genotypes through breeding.
