冀中南棉花新品种产量性状与品质性状的综合评价分析

通过对冀中南种植棉花新品种进行产量品质性状的综合评价分析，结果表明在不同的生态环境条件下，供试棉花品种产量性状以单铃重的变异系数最大，纤维品质性状以马克隆值的变异系数最大。通径分析的结果表明，按照直接通径系数由高到低排序，产量构成因子中的衣分＞单株铃数＞单铃重＞籽指，纤维品质性状中的整齐度指数＞断裂比强度＞马克隆值＞伸长率＞上半部平均长度。前3个主成分的累计方差贡献率达87．263％，基本反映供试棉花品种10个主要性状的绝大部分信息。...

The yield characters and quality characters of several new cotton varieties in the mid -south area of Hebei province were comprehensively evaluated in this paper .In different ecological environments , the single-boll weight of tested cotton varieties had the biggest variation coefficient among yield characters , and micronaire value had the biggest variation coefficient among fiber quality characters .Path analysis indicated that the direct path coefficients of various characters had the flowering order ：lint percent-age〉number of bolls
