| 摘 要： | 利用Ta1显性雄性核不育基因 ,创立了Ta1轮回—交替选择育种技术。通过多个优异亲本的复合杂交组建轮回选择群体 ,经C4～ 6代的轮回选择以及轮选后代的逆境与非逆境环境的交替选择 ,使基因广泛交流和重组 ,实现了主效基因的有效结合和微效基因的相互累加。产生了丰富多样的基因型 ,育成了一批遗传基础丰富 ,背景广阔 ,具有多抗、节水、高产稳产特性的小麦新品种和苗头品系 ,为抗逆性小麦育种开辟了新路。

| Abstract: | Using the dominant male - sterile gene(Tal),the breeding technique of recurrent selectio in wheat breeding was developed.Through the double crosses of male parents and female parents,recurrent selection populations were established.To break the unfavorable gene linkage and enhance the frequency of accumulation and recombination of desired genes,several times of alternate selection were done with the recurrent filial generation,and many varieties with the characters of high yield,multi-resistance had been developed.This technique provides a new method for wheat breeding. |
