| 摘 要： | 对粳稻半矮秆突变体Y98149矮生性遗传研究的结果表明:(1)控制半矮秆材料Y98149矮生性表达的基因为一对显性核基因;(2)该显性基因与控制KL908矮生性表达的显性核基因及控制AKs1-108矮生性表达的隐性核基因sd-1均非等位;(3)分析F2群体株高资料后认为,在C078遗传背景下,可以检出在近等基因系遗传背景下无法检出的另一对显性主基

| Abstract: | Based on the analysis of F 1 and F 2 from reciprocal cross, We found that.(1) The semi dwarfism of the mutant plant was controlled by a pair of dominant nuclear genes, not affected by cytoplasm. (2)The semi dwarf gene in Y98149 was nonallelic to the semi dwarf gene in KL908,and sd 1 gene in AKs1 10 respectively,but additive genetic effect was found between them. Some questions were discussed. |
