摘要
大豆是典型的自花授粉农作物,天然异交结实率不到1％.大豆雄性不育利用为大豆杂交育种开启了一扇大门,有效地挖掘了大豆的生产潜力,为大豆产量的提高提供了有效的途径.大豆雄性不育最早在20世纪20年代被发现,现在已挖掘出来的大豆雄性不育材料中,多数是由细胞核基因控制的,少数是由细胞质控制的.我国在选育大豆细胞质雄性不育方面是遥遥领先的.综述了大豆雄性不育的分类和利用杂种优势上所取得的进展,探讨了利用大豆杂种优势中出现的主要问题,展望了大豆雄性不育在杂种优势利用方面的前景.
Abstract
Soybean is a typical self-pollination crop,the rate of natural cross pollination is less than 1％.Soybean male-sterility is used to open a door for soybean cross breeding,the productive potential of soybean is effectively excavated,it provides an effective way to increase the yield of soybean.The very earliest soybean male-sterility was discovered in the 1920s.Among the discovered material,most of the male-sterility is controlled by nuclear genes,the small part is cytoplasmic male-sterility.Under the aspect of selecting and breeding cytoplasmic male-sterility materials,China is in the leading position in the world.This paper summarized the latest progress in the development of male-sterility and hybrid utilization of soybean,it analyzed some main problems in the utilization of soybean heterosis and put forward the prospect of discovered male-sterility in utilizing soybean heterosis in future.
