利用人工诱变,发展杂交优势,在玉米、 高梁、大麦、洋葱等作物上已取得成就,如诱发产生了胞质雄性不育等。 杂交水稻的三系培育已由用现有品种广泛测交筛选,发展为定向培育。突变育种作为一种手段,在改造培育三系、配组强优势组合中的作用,已成为当前国内外注意探讨的一个问题 The use of artificial mutagenesis, the development of heterosis, in corn, sorghum, barley, onions and other crops have been made, such as induced cytoplasmic male sterility. Three-line hybrid rice cultivation has been using a wide range of existing varieties tested by screening, the development of directional cultivation. As a means of mutation mutation breeding, it plays an important role in reforming and cultivating the combination of three lines and strong combination in the group, which has become a problem to be explored at home and abroad
