自Wison和Ross 1962年选育出较有实用价值的T型不育系和相应的恢复系以来,经过几十年的努力,小麦雄性不育杂种优势利用研究已经取得许多重要进展.然而由于恢复源较少,种子皱缩,群体杂种优势不够显著等原因至今未能大面积应用于生产.粘型和易型虽能较好地克服T型存在的一些问题,如恢复源和种子饱满度等,但同时存在不育系和杂种子一 Since Wison and Ross bred more practical T-type CMSs and their restorer lines in 1962, decades of hard work have made important advances in the utilization of wheat male-sterile heterosis. However, Such as fewer sources, shrinkage of seeds, insufficient population heterosis, and so on, have not been applied to large-scale production so far. Although viscous and easy types can overcome some problems of T type, such as recovery source and seed fullness , But at the same time there is a sterile line and hybrid seed one
