Abstract:

Salinity has negative impact on plants such as poor germination, reduction in root length, reduction in shoot length and adverse effect on early seedling growth. In order to study the effect of salinity (NaCl 180 mM) on seed germination of soybean, an experiment was conducted to screen 82 diverse soybean genotypes. The results revealed that salinity stress caused by NaCl reduced both germination percentage and seedling growth of soybean varieties. Genotypes differed significantly in terms of tolerance to salinity. Mean seed germination of the 82 soybean genotypes under normal condition was 90.69% whereas the mean seed germination under salt stress was 8.82%. Out of 82 lines screened at 180mM NaCl, sixty six genotypes failed to germinate (0% germination). Only sixteen genotypes showed germination. The seed germination among these sixteen genotypes varied from 3.33 per cent to 100per cent. Three genotypes Pusa 9712, PS-1572 and FT-ABYARA exhibited 100% seed germination. Whereas genotypes E-20, JS-20-19 and Bragg showed 73.33%, 63.33% and 80% seed germination respectively under salt stress.
