太谷核不育小麦是由显性雄性不育单基因控制的不育小麦,它的细胞质正常,开花时颖壳张开角度大,雌蕊柱头外露,便于接受外来花粉,在麦类育种和遗传研究中有重要价值。定位这个显性不育基因,对于广泛而有效地利用这个基因是十分必要的。目前定位小麦雄性不育基因还没有一个十分成功的方法,这是因为含有不育基因的不育株只能作母本,对它很难进行单体分析.我们设计了一种端体分析方案,在端体分析的同时,我们还对这个基因进行了染色体组定位,以提高端体分析的准确性和减少工作量。
Taigu nuclear sterile wheat is dominated by the dominant male sterility single gene-controlled sterile wheat, its cytoplasm is normal, flowering husk open angle, pistil stigma exposed, easy to accept foreign pollen, wheat breeding and genetic Research has important value. Locating this dominant sterility gene is essential for the extensive and efficient use of this gene. At present, there is not a very successful method for locating the male sterility gene of wheat because the sterile gene containing the sterile gene can only be used as the female parent, and it is very difficult to carry out the monomer analysis for it. At the same time as the endbody analysis, we also performed a genome-wide mapping of this gene to improve the accuracy of endbody analysis and reduce the workload.
