水稻香味的遗传及其利用初探

STUDY ON HEREDITY AND UTILIZATION OF FRAGRANCE IN RICE

通过不同类型、不同来源的香稻与非香稻品种（材料）之间杂交，采用ＫＯＨ法鉴定杂交组合双亲、Ｆ１、Ｆ２植株叶片的香味，统计Ｆ２植株无香味对香味的分离比率。结果表明：水稻香味性状是受一对隐性主效基因所控制。

By using the techniques of crossing between the fragrant and non fragrant varieties in rice from different types as background,the aroma of rice leaves of P 1,P 2,F 1,F 2,was identified by means of KOH solution method.According to statistics about the segregation ratio of fragrant to non fragrant in F 2.The results showed that aroma was mainly controlled by a couple of recessive genes.It was also discussed about how to utilize this character in breeding of rice.
