Arsenic contamination in rice would be a serious problem for uman ealt . A screening program was conducted at germination and early seedling stage of rice cultivars w ic were grown under plate culture and ydroponic culture condition. Five different concentrations of arsenate viz.T1 (1ppm), T2 (3ppm), T3 (6ppm), T4(9ppm), T5 (12ppm) and distilled water (control) were applied on seven cultivars of rice suc as BR-26, BRRI-28, BRRI-29, BRRI-45, BRRI-50, BR-3 and BR-14.T e germination percentage and tolerant percentage, root lengt and s oot lengt and biomass or seedling dry weig t decreased significantly wit t e increase of arsenic levels.Among seven cultivars, BRRI-29 s owed t e maximum percentage of germination and tolerant percentage, BR-26 produced t e ig est root lengt and s oot lengt to ig est arsenic concentration (12 ppm) w ereas maximum biomass was obtained for BR-14.
