本文对我国生产上应用的短季低酚棉品种及近几年参加各区域试验的新品系４０份材料进行农艺性状和品质特性分析研究，并与当前在黄河流域推广的短季低酚棉品种中无２６８进行了系统比较。结果表明，该资源群体单株结铃数平均值仅有１４．３个，与推广品种中无２６８相比偏少。单铃重平均值为５．９ｇ，远大于推广品种中无２６８；衣分偏低，平均值为３５．４２％，中无２６８的衣分处于此值附近；２．５％跨长、比强度、马克隆值平均值分别为２８．８ｍｍ，２１．９ｇ／ｔｅｘ，４．５ｍｉｃ。长度基本符合纺织工业要求，无论是群体平均值，还是现今推广品种中元２６８均表现比强度偏低、纤维整齐度较好。生育期平均值１０９．８ｄ，大多数品种在１０５～１１５ｄ范围之内。推广品种中无２６８表现出较短的生育期。蛋白质含量平均值为４０．０７，变幅大，变异潜力小。棉酚含量平均值０．０１６５，符合国际卫生标准。未达国际卫生标准的仅占６．７％。
This paper analyzes the agronomic traits and quality traits of 40 short-season, low-phenolic cotton varieties used in production in China and 40 new lines tested in various regions in recent years. No 268 in the system comparison. The results showed that the average number of bolls per plant in this resource group was only 14.3, which was less than that in 268 varieties. Single boll weight average of 5.9g, far greater than the promotion of varieties without 268; clothing low, with an average of 35.42%, no 268 in the vicinity of this value; 2.5% across long, than The average values of the intensity and micronaire were 28.8 mm, 21.9 g / tex, 4.5 micrometers, respectively. The length of the basic line with the requirements of the textile industry, both the average group, or the current promotion varieties Zhongyuan 268 are lower than the intensity of performance, better fiber uniformity. The average growth period of 109.8d, most of the varieties in the range of 105 ~ 115d. None of the popularized varieties exhibited shorter growth periods. The average protein content of 40.07, large amplitude, small variation potential. Gossypol content of 0.0165, in line with international health standards. Only 6.7% fell short of international health standards.
