2007—2008年以11个新配置的杂交组合和对照农杂66为材料,通过田间比较试验,检测了主要纤维品质指标。结果表明:除反射率外,纤维长度、比强度、伸长率、麦克隆值、黄度、短纤维指数、整齐度各组合(品种)间存在显著差异或极显著差异;从纤维品质的整体方面来看,参试组合中纤维品质最好的是农杂417,其次是农杂420,最差的是农杂441;从各组合纤维品质性状变异系数的均值来看,黄度的变异系数最大,平均为10.04%,整齐度的变异系数最小,平均为0.59%,大小依次为:黄度>麦克隆值>短纤维指数>比强度>伸长率>长度>反射率>整齐度。
From 2007 to 2008, 11 newly-arranged hybrid combinations and control Nongza 66 were used as materials. The main fiber quality indexes were tested through field experiments. The results showed that there were significant differences or extremely significant differences in fiber length, specific strength, elongation, micronaire, yellowness, short fiber index and uniformity among all combinations (varieties) except for reflectance. From the aspects of fiber quality In terms of fiber quality, the best fiber quality was Nongza 417, Nongzazhu 420 and Nongnong 441, respectively. The coefficient of variation of yellowness The average was 10.04%. The coefficient of variation of uniformity was the smallest with an average of 0.59%. The order of magnitude was: yellowness> micronaire> short fiber index> specific strength> elongation> length> reflectance> uniformity.
