以不同历史时期的10个代表性棉花品种的2年5点实验和1973～1996年棉花品种区域实验的历史资料，研究我国黄淮棉区自50年代以来棉花品种农艺性状、抗病性和稳定性的遗传改良效果。结果表明：建国40多年来，该棉区棉花早熟性和抗病性育种取得显著进展。在品种的产量和品质提高的同时，品种的生育期缩短了3～5天，霜前花率提高了近7个百分点。棉花品种的抗病性也显著提高。抗枯萎病问题已基本解决，抗黄萎病问题正在解决。棉花品种的稳定性也有了一定程度的改善。
Based on the historical data of 5 representative experiments of 10 representative cotton cultivars in different historical periods and the experimental data of the cotton cultivars from 1973 to 1996, the agronomic traits, disease resistance and stability of cotton cultivars in the Huanghuai cotton area of China since the 1950s were studied Sexual genetic improvement. The results showed that over 40 years after the founding of the People’s Republic of China, cotton precocious and disease-resistant breeding has made remarkable progress. In the varieties of yield and quality improvement at the same time, the variety of the growth period shortened 3 to 5 days, before frost flower rate increased by nearly 7 percentage points. Disease resistance of cotton varieties also significantly increased. Fusarium wilt problems have been basically solved, the problem of Verticillium wilt is being solved. The stability of cotton varieties also improved to some extent.
