Hybridization betweenRiceand Normal Tartary Buckwheat and Hull Features in the F2 Segregates

摘要：

Reciprocal crosses betweenriceTartary buckwheat, which has dark and non-adhering hull, and normal Tartary buckwheat(var．Hokkai T8), which has light brown and adhering hull, were carried out using hot water emasculation method we had developed. The hulls of F2 seeds set on the F1 plants were all dark and adhering in both reciprocal crosses, suggesting that non-adhering hull was recessive trait. In F2(F3 seeds), the segregation pattem fitted 3：1 ratio of adhering：non-adhering, suggesting that non-adhering hull ofriceTartary buckwheat was controlled by single recessive gene．AISO, the segregation pattern fitted 3：1 ratio of dark hull：light brown hull, suggesting that light brown hull ofHokkai T8Was also controlled by single recessive gene．
