我国无毒棉育种起于70年代中期,荆州地区农科所早在1974年就从“安通—21”的天然变异株中经过单株选择育成“4588”品系。据当年测定,产量、品质接近或超过当时推广的鄂光棉,蛋白质含量为49.5%,脂肪为19.8%,其中脂肪中油酸占60%,棉酚含量下降到万分之一,符合检验标准。后因工业去酚工艺的推广,实验经费匮缺,试验中 Since the breeding of non-toxic cotton in China began in the mid-1970s, the agricultural science institute in Jingzhou district was bred from the “4588” strain of “Antong-21” through single plant selection as early as 1974. According to the current measurement, production, quality close to or beyond the then promotion of E Guangmian, the protein content of 49.5%, 19.8% fat, of which 60% oleic acid in fat, gossypol content fell to one ten thousandth, in line with test standards. After the industrial process to the promotion of phenol, lack of experimental funding, testing
