以川香２８Ａ和川香８４Ａ与无香味的恢复系ＣＤＲ２２、成恢１７７等杂交，研究Ｆ１和Ｆ２单粒稻米的香味遗传特点。结果表明Ｆ１稻米无香味，恢复系的无香味表现胚乳直感现象；杂种稻米（Ｆ２）无香味：有香味符合１５：１的遗传分离比。川香２８Ａ与香稻恢复系６３６杂交，Ｆ１和杂种稻米（Ｆ２）的每粒米都有香味。结合过去的有关研究，提出杂交香稻香味道传的双基因模式。介绍了运用香稻亲本转育香味基因，选育香稻保持系、恢复系和杂交香稻的育种方法和进展。
The genetic characteristics of the scent of F1 and F2 single grain rice were studied by crossing Chuanxiang 28A and Chuanxiang 84A with non-fragrant restoration lines CDR22 and Chenghui177. The results showed that there was no fragrance in F1 rice, and the no-fragrance of restorer line showed the phenomenon of endosperm inhomogeneity. Hybrid rice (F2) had no fragrance: the flavor had a genetic segregation ratio of 15: 1. Chuanxiang 28A crossed with Aromatic Rice Restorer Line 636, and each grain of F1 and hybrid rice (F2) had a scent. Combined with the related research in the past, the bi-gene model of aromatic smell of hybrid aroma rice was proposed. The breeding method and progress of using fragrant rice parents to turn on scent genes, breeding fragrant rice maintainer lines, restorer lines and hybrid fragrant rice were introduced.
