Abstract: The present experiment has been designed to study the effect of 100 µM cadmium stress on 14 genotypes of mungbean [Vigna radiata (L.) Wilczek] at seedling growth stage. The data revealed that 100 µM cadmium concentrations did not produce any significant change in seed germination as compared to control but the root showed more sensitivity to cadmium stress than shoot. Perusal of the data exhibited significant reduction of dry weight of root, shoot, leaf and whole seedling under cadmium stress in all fourteen genotypes studied. Among all the genotypes, the highest stress tolerance index (STI) was registered by Samrat (90.10%), PDM 54(88.90%), Pusa Baisakhi (85.98%), IPM 02-03(85.49%) and K 851 (82.87%) were considered to be tolerant and genotypes IPM 03-01, Meha, PDM 84-139, B1 and Bireswar with 65.30%, 69.54%, 69.67% 70.81% and 71.24% STI, respectively were considered as susceptible to cadmium treatment in the present study. In general, the root showed much higher accumulation of cadmium than shoot and leaf. Rate of uptake of cadmium in the root in tolerant genotypes was also found to be lower than the susceptible ones.
