摘要: 【目的】 研究新疆绿洲干旱区不同棉种主要综合性状,综合评价南疆生产上推广应用的棉花品种,为南疆品种选择和提质增效栽培提供一定的理论依据。【方法】 以新疆南疆棉区历来选育的有代表性的16个品种为材料,分析新疆干旱绿洲区栽培下棉花农艺形状、品质、根系、产量及产量构成因子等主要性状相关性和聚类分析。【结果】 各品种铃重为4.5~6.5 g,单株铃数和产量10-108-3最多,铃数与产量的灰色关联度最大,其值为0.93。籽指与籽棉重、纤维重为显著正相关,相关系数分别为0.492、0.538,衣分与种子数呈显著负相关,相关系数为-0.532。各品种马克隆值为4.62~5.73,比强度与马克隆值呈负相关,与伸长率呈正相关关系。【结论】 总根长与果节始节、果枝数、伸长率呈显著正相关,生育期与子叶节高度、果枝数呈负相关关系,与果节始节、比强度、伸长率呈显著正相关。

Abstract: 【Objective】 Comprehensive Evaluation and Analysis of Main Characters of Different Cotton Cultivars in Oasis Arid Area in Xinjiang. This study can provide some theoretical basis for variety selection and cultivation of quality and efficiency cottons in southern Xinjiang. 【Methods】 In this study, the correlation and cluster analysis of the agronomic traits, quality, root system, yield and yield components of cotton under cultivation in oasis arid area of Xinjiang were conducted based on 16 representative cultivars of cotton in southern Xinjiang. 【Results】 The results showed that the boll weight of the per plant was 4.5-6.5 g, the number of bolls per plant and the yield of 10-108-3 were the highest, and the grey correlation between boll number and yield was the largest, with a value of 0.93. There was a significant positive correlation between seed index and seed cotton weight and fiber weight, with coefficients of 0.492 and 0.538, respectively. There was a significant negative correlation between seed index and seed number, and the correlation coefficient was -0.532. The Micronaire value of each cultivar was 4.62-5.73, the specific intensity was negatively correlated with the Micronaire value, and it was positively correlated with the elongation. 【Conclusion】 The total root length was significantly positively correlated with the initial section, the number of fruit branches, and the elongation rate. The growth period was negatively correlated with the height of the cotyledonary node and the number of fruit branches, and was significantly correlated with the initial section, specific strength and elongation rate.
