| 摘 要： | 选择４个抗棉铃虫品种（系）和４个常规品种（系），从产量及其构成因素、纤维品质、农艺性状进行了比较研究。结果表明，抗棉铃虫品种产量低于常规品种产量，主要原因是抗虫品种单铃重偏低，其次是抗虫品种生长期偏短和生长势偏弱。纤维品质指标都能满足纺织工业的要求。

| Abstract: | Four resistant pest varieties and four standard varieties were studied by the compairson of their yield,yield components, fibre quality and agronomic traits The results indicated that yield of bollworm resistant cotton varieties was lower than that of traditional varieties The main reason was insect resistant varieties had lower boll weight, secondly shorter growth stage and weaker growth vigor and development Fiber quality of insect resistant varieties was fit for spinning industry |
