摘要： 对145个国内外不同来源的低酚棉品种系）的研究表明，中国低酚棉品种资源群体的基本特点是，皮棉产量的变异潜力较大；铃重、衣分、子指、衣指变异度较小，纤维品质性状的变异度表现相似。多数品种系）的衣分偏低，子指较大；纤维强度低，细度中等，但纤维较长且整齐度好。在产量或品质性状方面，该资源群体含有一些特异种质；国内育成品种系）在衣分、细度上可更好地提供优异的基因资源，而国外品种系）在铃重、衣指、纤维强度方面具有较高的特异种质筛选率。

Abstract: The population composed of 145 varietiesstrains)of glandless cotton from home and abroad was studied during 1988-1990.The results indicated that the population was characterized by higher variability in lift yield, and by lower in boll weight,lint percentage,seed index,lint index lint index and fibre characters.Most varieties possessed the properties of lower lint percentage and fibre strength,medium fibre fineness,longer fibre,better uniformity and high seed index.The germplasms with specific target traits were screened out of the population.The varieties from China could provide better gene resources in lint percentage and fibre fineness, and the foreign cottons could do better in boll weight,lint index and fibre strength.

Key words: Glandless cotton, Yield character, Fibre quality, Genetic resources
