摘要
"十一五"期间我国通过国家和省级审定的棉花品种(杂交种)达600多个,其中白色陆地棉品种(杂交种)的纤维长度主要分布在29～30 mm,长度整齐度指数主要集中在84%～85%,断裂比强度主要在28～30cN.tex-1,麦克隆值则多在4.3以上。90%以上的品种(杂交种)符合优质棉品质的要求。前3项指标优于美国现行推广品种,但麦克隆值却明显偏高。对纤维品质的主要分布特点、转基因与杂交种情况、品种多乱杂、品质区划等问题进行了讨论并提出一些对策建议。
More than 600 cotton varieties （hybrids） were examined and approved by the National and Provincial Committees of Crop Variety Identification from 2006- 2010. For the white-fiber varieties of upland cotton, the upper-half mean length ranged mainly between 29-30 mm; the uniformity index was mainly in the range of 84%-85%; fiber strength varied mainly from 28-30 cN. tex-1; and micronaire values were mostly over 4.3. Over 90% varieties met the standards for high-quality cotton. Most of the white upland cotton varieties were better than the varieties released in the United States with respect to upper-half mean length, uniformity index, and fiber strength, but the micronaire values were too high. This paper discussed some problems and potential suggestions for improvement.
