Physiological Screening of Green Gram (Vigna radiata L.) Varieties by Seedling Germination Traits under Salinity Stress

Among the legumes, pulses are the most important component in India as they have very high protein resources. Green gram (Vigna radiata) is the most essential one when compared to other pulses regarding high nutritional value, enriching soil fertility and being a short duration crop. In India, pulses cultivation faces salinity stress which is a most constraint factor on its production. Hence, an experiment was performed with the purpose of analyzing morpho- physiological differences in high difference green gram varieties, which are MH 421,VBN 2,VBN 4,CO 8 and CO(Gg) 912 under salinity stress condition. This experiment was done at laboratory condition under various concentration level of Sodium Chloride (NaCl). These levels create different levels of salinity stress, the above five green gram varieties where screened for identifying their salinity stress and the important parameters which include radicle length, shoot length, plant height, germination percentage and seed Vigor were recorded.
