摘要: 【目的】综合评价海岛棉的抗旱性,挖掘抗旱性强的种质资源。【方法】以203份海岛棉资源为材料,在大田对棉花花铃期进行干旱胁迫,研究与抗旱性相关的农艺性状,以抗旱系数和主成分分析及聚类分析相结合,对海岛棉品种的抗旱水平进行综合性评价。【结果】在两个点上,203份材料在农艺性状上存在一定的差异。203份材料农艺性状指标的综合抗旱系数和抗旱性量度值(D 值) 的评价结果基本一致。D值聚类分析203份海岛棉资源材料分为5大类。【结论】通过主成分分析、综合抗旱系数评价分析,单株产量、单铃重和株高3个抗旱性评价指标,能直观、简单和可靠的评价棉花花铃期种质资源的抗旱性。

Abstract: 【Objective】 To comprehensively evaluate the drought resistance of island cotton, and explore the germplasm resources with strong drought resistance.【Method】203 island cotton varieties were used as experimental materials, drought stress was carried out on cotton boll period in daejeon, the agronomic traits related to drought resistance were examined, and the drought resistance level of island cotton varieties was evaluated by combination of drought resistance coefficient, principal component analysis and cluster analysis. 【Results】There were some differences in agronomic traits between the 203 materials at two points, and the evaluation results of the comprehensive drought resistance coefficient and the measured value of drought resistance (D value) were basically consistent. According to the results of D value cluster analysis, 203 Gossypium barbadense L. resource materials were divided into 5 categories.【Conclusion】 Through principal component analysis and comprehensive drought resistance coefficient evaluation and analysis, three drought resistance indexes, yield per plant, boll weight and plant height can be used to evaluate drought resistance of cotton at flowering and boll period intuitively, simply and reliably.

Key words: Gossypium barbadense L; cluster analysis; agronomic traits; principal component analysis
