【摘要】 采用菌土置入法对大白菜进行根肿病抗病接种鉴定;根据大白菜核基因雄性不育复等位基因遗传假说,对26个抗根肿病自交系育性基因进行测定。结果显示,自交系中以纯合显性恢复基因型MsfMsf为主(17个,占65%),纯合隐性可育基因型msms也比较常见(6个,占23%),同时发现了杂合体的可育基因型Msfms(3个,占12%)。通过特意的试验设计验证:抗性基因(R、r)与育性基因(Msf、Ms、ms)是独立遗传关系。更多还原

【Abstract】 The relation between clubroot resistance genes and fertility genes in Chinese cabbage were studied .In accord ance with Multiple Allele Hypothesis of Chinese cabbage,genotypes of 26 self-lines with resistance to clubroot were identified by sexual hybridization with AB742 and 47A.3 genotypes(Ms~ f Ms~ f ,Ms~ f ms,msms)were discovered.17 of them were Ms~ f Ms~ f ,6 were msms and 3 were Ms~ f ms.A special design was carried out to test the relation between clubroot resis- tance gene(R,r)and fertility genes(Ms~ f ,Ms,ms).The results showed that they were inherited independently.更多还原
