Studies on Effect of Salinity Stress on Vigna radiata (L.) Wilczek Cultivar, Naval

Abstract

Amol Chandrakant Vikhe* and Janardhan Nehul

(Vigna radiata L.) Wilczek is short duration crop cultivated over world in Kharif, Rabi and Summer season. Area under mung bean cultivation is increased in india since 2019-2021. Mung bean crop is affected by biotic and abiotic factors such as salinity, water logging and drought in kharif, rabi and summer season. Salinity of the soil is abiotic the main responsible factor which reduces the seed germination, plant growth and crop yield. The salinity stress was studied in this experiment on isolated mutants from Vigna radiata (L.) Wilczek cultivar- Naval. The isolated mutants from mutagenic treatments of EMS, SA and Gamma radiation in M3 generation were studied. The research experiment was carried out in New Arts, Commerce and Science college Ahmednagar (MS, India 2021). The selected mutants from M3 generation were B8, B13, B19 and B21 from EMS-15, 20mM; and SA-2, 2mM respectively. The mutants were with high yield and biochemically diverse from control Cultivar-Naval. These mutants were subjected to salinity stress using Sodium chloride. Different concentrations of NaCl were used such as, NaCl- 0, 200, 225, 250 and 300 mM. The experiment was conducted in laboratory as well as in the field condition. These Mutants were tested for seed germination, vigour, electrical conductivity, seed yield. These mutants showed significant variations in said parameters as compared to control Cultivar-Naval.
