【摘要】 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。更多还原

【Abstract】 The crosses were made between the aromatic cytoplasmic male sterile (CMS) lines Chuanxiang 28A and Chuanxiang84A and non--aromatic restorers CDR22, CH047, DH1, CH90625, and CH177 to study the genetic characteristics of aroma of singlegrain in F, and F, progenies. The results indicated that each grain in F, was non-aromatic, and non-aroma of restorers was xenia, andhybrid rice grains (the F, progenies)segregated at a 15: 1 (non-aromatic: aromatic)ratio. Each grain of F, and F: of Chuanxiang 28Acrossed with aromatic restorer 636 was aromatic. The pattern of double genes of aroma in aromatic hybrid rice was proposed and breeding methods and progress in aromatic maintainers and restorers and hybrids by using aromatic genes of rice germplasm were introduced.更多还原
