为了了解近年来河北省育成棉花品种的纤维品质状况，对今后棉花品种改良提供指导，通过对比分析的方法对河北省2009—2013年审定的44个棉花品种的纤维品质进行了研究。结果表明：近5年河北省审定棉花品种的纤维品质同2004—2008年审定品种纤维品质比较，上半部平均长度基本持平、断裂比强度略有提高、马克隆值有所增加；与全国及其他省份棉花品种相比上半部平均长度和断裂断裂比强度偏低，马克隆值偏高。河北省近年来棉花品种纤维品质改良效果不明显。

To study the fiber quality of cotton variety examined and approved by Hebei Province and provide guidance for future cotton varietal improvement, the fiber quality of 44 cotton varieties examined and approved by Hebei Province during 2009-2013 were researched. By comparing with the cotton varieties examined and approved during 2004- 2008, the upper half mean length were basically flat, the fiber strength and the micronaire are higher. By comparing with the cotton varieties bred by the nation and the other provinces, the upper half mean length and fiber strength of the varieties bred by Hebei Province are lower, the micronaire was higher and the ntegrated cotton fiber quality was poor. The effect about genetic improvement of fiber quality was not obvious in recent five years.
