In order to investigate the genotypic differences in Cu accumulation of rice, 35 rice cultivars of different cultivar groups (temperate japonica, tropical japonica, tongil, and indica) were cultivated in a field condition that rice was irrigated by irrigation water containing 2 ppm Cu throughout all growing season in 2007. Thirty-five rice cultivars showed large differences in Cu concentrations in all rice parts, including root, shoot, straw, grain, chaff, brown rice, rice bran, and polished rice. Cu concentrations in polished rice ranged from 0.78 to 2.84 mg/kg. The total Cu accumulation of shoot varied from 1.31 to 4.54 mg/m2. Indica and tongil cultivar groups presented the higher Cu concentration and accumulation comparing the two japonica rice cultivar groups (temperate japonica and tropical japonica). The large genotypic variation suggested the possibility of breeding low Cu accumulating rice cultivar.
