Abstract:

Filed experiments were carried out to screen enriched-selenium(Se) cultivars from late rice cultivars (63 cultivars, include main cultivars and ones which are going to be popularized) and early rice cultivars (12 main cultivars). The results showed that: Se contents in brown rice and polished rice of different cultivars are obviously distinct. The maximum may be 4-5 times of the minimum. Therefore, the screening of enriched-Se rice cultivars is necessary. Enriched-Se rice cultivars will be obtained when a range of Se content (0.1~0.3mg/kg) is took as enriched-Se foods standard from late rice cultivars, i.e. Gufengyou8312, BoIIyou510, Nanfengyou61208, Jiefengyou629, Jing5you182, Rexiang1, Nanfengyou/6256 and BoIIyou629. In early rice cultivars, Hongtaiyou996, IIyou128, Congyou629, IIyou202 and Teyou57353 are enriched-Se cultivars.
