早在1935年,印度在“百万棉”中就发现棉花雄性不育株。但是从利用杂种优势的角度来研究棉花雄性不育的利用价值,还是近二十年才开始的。美国、苏联、印度、巴西等国先后都有所报道。 国内从1972年开始也陆续发现和培育了一些棉花雄性不育材料。主要有“洞A”、“KK—1188—120A”、“KK—1188—119A”、“新海1号A”、“社A”、“广70—1”等。四川省棉花雄性不育杂种优势利用协作组对“洞A”雄性不育性状进行了初步的研究和遗传分析,认为其不育性状主要受一对隐性核基因的影响。
As early as 1935, India in the “one million cotton” found cotton male sterile plants. However, it has been almost twenty years since the utilization of cotton male sterility has been studied from the perspective of heterosis. The United States, the Soviet Union, India, Brazil and other countries have reported. Since 1972, some domestic cotton male sterile materials have also been found and cultivated in China. Mainly “hole A”, “KK-1188-120A”, “KK-1188-119A”, “Xinhai 1 A”, “community A”, “wide 70-1” and so on. Cotton Male Sterile Hybrids in Sichuan Province A preliminary study and genetic analysis on the male sterility trait of “Dong A” were carried out in the cooperative group. The results showed that the male sterility traits were mainly affected by a pair of recessive nuclear genes.
