经过8年的研究、筛选,中国科研人员成功培育出棉花雄性不育系6001A品种,攻克棉花育种世界难题。棉花是一种雌雄同花作物,目前国内外普遍采用人工去雄授粉生产杂交种子,但这种方法成本高,种子质量难以保证。这就需要利用科技手段,培育天然的无雄性棉花,俗称棉花雄性不育系。上世纪30年代,美国利用野生哈克尼棉培育出棉花雄 After eight years of research and screening, Chinese researchers successfully cultivated the 6001A cotton male sterile line to overcome the world-wide problem of cotton breeding. Cotton is a monoecious crop. At present, artificial dehuman pollination is used to produce hybrid seeds at home and abroad. However, the cost of this method is high, and the seed quality is hard to guarantee. This requires the use of scientific and technological means to cultivate natural non-male cotton, commonly known as cotton male sterile lines. In the 1930s, the United States used wild Hackney cotton to breed cotton males
