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。
Studies on 145 low-phenolic cotton varieties (lines) from different sources both at home and abroad showed that the basic characteristics of low-phenolic cotton varieties in China are that the potential for variation of lint yield is relatively large; the weight of boll, lint, The variation degree is smaller, and the variation degree of fiber quality traits is similar. The majority of varieties (lines) of the lower clothing points, sub-finger larger; fiber strength is low, medium fineness, but the fiber is long and good uniformity. In terms of yield or quality traits, this resource group contains some specific germplasms; domestic cultivars (lines) may provide superior genetic resources in terms of grain size and fineness, while foreign cultivars (lines) Refers to the higher fiber-specific screening rate of specific germplasm.
