| 摘 要： | 概述了国内外航天育种研究的进展和应用领域,阐述了空间诱变对农作物生物学性状的效应以及我国航天育种的成就。空间辐射对农作物性状的诱变具有不确定性,但诱变后代变异范围大,稳定快,而且还会出现常规育种不易出现的变异。不同品种对空间辐射的相应存在差异。已经育成的水稻、小麦、棉花、大豆、芝麻等农作物新品种在生产上发挥了比较大的作用,并取得了显著的经济效益和社会效益。

| Abstract: | The application and achievements of space irradiation breeding were outlined in the present review.The effects of space irradiation on biological traits and cultivar development in China were also described.Although space radiation resulted in diverse direction of variation in certain traits of field crops,the range of variation was wide and unique variants might be present in the treated progenies.The responses of different genotypes varied to space irradiation.A number of field crop cultivars,such as rice,wheat,cotton,soybean,and sesame,were commercially released. |
