摘要
１９７８ 年开始选用含棉花核雄性不育基因ｍ ｓ１４的两用系４７３Ａ、抗枯萎病品种陕棉９ 号及抗枯黄萎病品种中棉所１２， 通过杂交转育、病圃与非病圃、可育株与不育株的双重交叉选择， 成功地培育出抗枯萎耐黄萎和抗枯萎抗黄萎的核不育两用系抗Ａ１ 和抗Ａ２。并对其抗性遗传、抗性与产量的配合力及其利用情况进行了研究， 以抗Ａ１ 和抗Ａ２ 作母本已选配成３ 个杂交种应用于生产。
By using cotton dual-purpose line 473A with male sterile gene ms14 , Shanmian 9 with resistance to fusarium wilt and CCRI 12 with resistance to fusarium and verticillium wilts, genetic male sterile dual-purpose line kangA 1 and kangA 2 by means of crossing transference and bidirectional selection to fertile plants and sterile plants in both disease nursery and field were conducted in from 1978 untill now. The inheritance of resistance, combining alility of resistance and lint yield and utilization of kangA 1 and kangA 2 were studied. Till now, using kangA 1 and kangA 2 as sterile lines 3 hybrids were selected and used in the production.
