【摘要】 近年来,空间诱变育种已成为空间生命科学研究方面的重要内容之一,即经过卫星搭载,生物在高真空、微重力、强辐射及其他因素的综合作用下产生变异,经过地面选育、筛选和固定变异,培育新品种。在植物方面,国内外已利用该技术培育了粮食作物、经济作物、花卉及菌类等高产、优质新品种(系)。空间诱变育种技术开创了育种的又一新途径,其在牧草育种的应用还不多,但前景广阔。更多还原

【Abstract】 In the past few years,spaceflight mutation breeding has become a big characteristic in the study of space life science.A lot of new high-produced and well qualitative cereals,flowers and antibiotics have been bred by the technique of spaceflight mutation breeding home and abroad.The variation are produced in many organisms traveled by satellite by means of the comprehensive effect like high vacuum,microgravity,intense radiation and so on;selected on the land,at last,the new cultivars are got,it’s breeding by spaceflight mutagenesis.Spaceflight mutation breeding opens up a new way for breeding,it isn’t usually applied in forage breeding field yet,the prospect is optimistic.更多还原
