A pet experiment was conducted to investigate cadmium(Cd) content in brown rices of 46 rice cultivars of 7 genotypes. Results show that the tested rice cultivars differed sharply between genotypes and vary from 0.428-2. 558 mg · kg^-1 in Cd accumulation when the soil Cd content is 2 mg · kg^-1. In terms of Cd content in grains,the 7 genotypes of rices are in the order of special rice 〉 conventional early rice(Indianica sp. ) 〉 three-lined hybrid rlce(Indianica sp. ) 〉 two-lined hybrid rice ( Indianica sp. ) 〉 conventional late rice ( Indianica ...
