| 摘 要： | 根据大白菜"核不育复等位基因遗传假说"、抗根肿病基因和球心色的遗传规律,提出抗根肿病桔红心大白菜甲型"两用系"转育模式。依照转育模式采用杂交、回交、自交、系内交和测交等方法,对不同转育世代依次进行球心色筛选、抗性鉴定、经济性状筛选和育性调查,经过4代转育得到抗根肿病桔红心大白菜甲型"两用系"。

| Abstract: | Orange head Chinese cabbage is becoming an important development direction of Chinese cabbage quality breeding for its fresh and lovely color,nutritional value and health value.Its production will be affected seversly by the rapid spreading of clubroot disease.In accordance with the Multiple Allele Hypothesis of genetic male sterility,genetic rules of anti-clubroot genes and head color,the transfer model of anti-clubroot AB lines type Ⅰof orange head Chinese cabbage were put forward.On the basis of the model,orange head genes were transferred to AB line typeⅠ of anti-clubroot Chinese cabbage by crossing,backcross,selfing,sibling and test-crossing.During the course of breeding,head color screening,resistance identification,economic characters sifting and fertility identification were carried out for the plants from each generation.AB lines typeⅠ of orange head plants with homozygosis resistant genes were generated after 4 generations. |
