A field experiment was carried out at Ramkrishna Ashram KVK Instructional Farm, Nimpith, South 24Parganas during the pre-kharif season, 2012 to evaluate the performance of 66 numbers of green gram (Vigna radiata L.) genotypes in low to medium saline soil in coastal saline belts of Sundarbans, West Bengal. Almost all the 66 cultivars selected for the experiments took 5-6 days for 75% germination of seedlings and 27-36 days to achieve 50% flowering. Final plant stand count was from 70-80%. The higher value of seed yield was observed in PUSA-2031 (1398 kg), 75.4% higher in comparison to the local check Chaiti moong (797 kg/ha) followed by KM-11-573 (1302 kg; 63.3% more than LC), SM-11-41 (1286 kg; 61.3% more than LC), KM-11-583 (1280 kg, 60.6% more than LC), KM-11-578 (1211 kg, 51.9% more than LC), respectively. The significantly higher values of other yield attributing traits were observed among the green gram genotypes. In case of root length, the above genotypes were found significantly lower (12.33-14.33 cm, 7.8-20.4%) than the Chaiti moong (LC) 15.5 cm. From the above experiment it may be concluded that in the similar situation as well as soil salinity condition the above green gram genotypes may prove to perform better than the local cultivar Chaiti moong for cultivation in the coastal saline regions of Sundarbans, West Bengal.
