从１９７８年开始，选用含棉花核雄性不育基因ｍｓｃ１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号，通过杂交转育、病圃与非病圃、可育株与不育株的双重双向选择，成功地培育出抗枯萎病、耐黄萎病和抗枯萎病、抗黄萎病的核不育两用系抗Ａ１和抗Ａ２，并对其抗性遗传、抗性与产量的配合力及利用情况进行了研究。用抗Ａ１和抗Ａ２作母本已选配成３个杂交种应用于生产。
Since 1978, the dual-line 473A containing the cotton nuclear male sterility gene msc1, the resistant cotton variety Shanmian 9 and the resistant cotton Verticillium wilt cotton variety No. 12 were selected and crossed by hybridization, nursery and non-disease Nursery, fertile plants and sterile lines of the two-way selection, successful breeding fusarium wilt, Verticillium wilt resistance and Fusarium wilt, Verticillium wilt resistant to both male sterile lines of A2 and anti-A2, and The inheritance of resistance, the combining ability of resistance and yield, and the utilization of them were studied. With the anti-A1 and anti-A2 as the mother has been selected into three hybrids used in the production.
