Abstract

The fiber quality of cotton (Gossypium barbadense L.) native to the Peruvian Amazon region is one of the most versatile and essential natural fibers in the Peruvian textile industry. There is little information about the fiber quality traits of cotton genotypes native to the Peruvian Amazon region. This study investigated the fiber quality traits of Peruvian Pima cotton accessions native to the Amazon region of the La Convención Province, Cusco, Peru, to determine the lines with the greatest potential for improving fiber quality in cotton genetic breeding programs. A total of 14 cotton accessions with white fiber color, being 12 accessions of G. barbadense L. (Pima cotton) and two accessions of Gossypium sp. (unknown cotton), were analyzed. The fiber properties determined using the high volume instrument method included seven characteristics. All fiber properties were classified into five quality classes. The data on fiber quality properties were subjected to distribution, correlation, and canonical variable analysis. The results of fiber quality properties showed that the two accessions of Gossypium sp. (unknown cotton) can be promising options to be used as high-quality fiber progenies in crop genetic breeding programs or can be cultivated by regional farmers for the purpose of producing cotton with high fiber quality. Future investigations could utilize other methods of fiber quality analysis and compare the fiber quality of these cotton accessions native to the Peruvian Amazon region with other cotton species grown worldwide to improve the understanding of Pima cotton fiber quality and its applicability in different contexts of the textile industries.

白皮马棉(Gossypium barbadense L.)主要纤维特征的比较分析:秘鲁亚马逊地区的原生品种
原产于秘鲁亚马逊地区的棉花(Gossypium barbadense L.)的纤维质量是秘鲁纺织业中用途最广、最基本的天然纤维之一。有关原产于秘鲁亚马逊地区的棉花基因型的纤维质量特性的信息很少。本研究调查了原产于秘鲁库斯科拉孔文西翁省亚马逊地区的秘鲁皮马棉品种的纤维品质特征,以确定在棉花遗传育种计划中最有潜力改善纤维品质的品系。研究共分析了 14 个白色纤维的棉花品种,其中 12 个是 G. barbadense L.(皮马棉)品种,2 个是 Gossypium sp.(未知棉)品种。使用高容量仪器法测定的纤维特性包括七个特征。所有纤维特性被分为五个质量等级。对纤维质量特性数据进行了分布分析、相关分析和典型变量分析。纤维质量特性的研究结果表明,这两个 Gossypium sp.(未知棉花)登录品系有希望成为作物遗传育种计划中的优质纤维后代,或可由地区农民种植,以生产优质纤维棉花。未来的研究可以利用其他纤维质量分析方法,将这些原产于秘鲁亚马逊地区的棉花品种的纤维质量与世界上种植的其他棉花品种的纤维质量进行比较,以提高对皮马棉纤维质量的认识及其在不同纺织工业环境中的适用性。
