西北植物研究所李振声研究员近年创建的具有遗传标记的蓝粒单体小麦系列,不用细胞学鉴定,仅凭观察种子颜色就可将二体、单体和缺体种子区别开来,有效地解决了单体小麦保存难和利用难的问题,而且基本没有单价染色体的漂移,对小麦基因定位和育种工作提供了重要的遗传工具。但蓝单体小麦冬性弱,在甘肃陇东不能越冬,因而在冬小麦染色体工程育种上难以直接利用。因此,在寒、旱生态区开展蓝单体及其缺体小麦转育研究,对冬小麦 Northwest Institute of Plant Li Zhensheng researcher created in recent years with genetic markers of blue-grain single wheat series, without cytological identification, just by observing the color of the seeds can be two bodies, monomer and missing seeds to distinguish between effectively resolved The problem of difficult storage and utilization of single wheat and little drift of monovalent chromosomes provided an important genetic tool for gene mapping and breeding of wheat. However, blue monomer wheat winter weak, winter in Gansu can not winter, so it is difficult to direct use of winter wheat chromosome engineering breeding. Therefore, in the cold and dry ecological zones blue cell and its lack of wheat to carry out the research on the transfer of winter wheat
