| 摘 要： | 对河南省2006年10个春棉区试品种的植株、产量因素和纤维品质共18个数量性状进行因子分析.结果表明:前5个公因子对所考察性状变异的累计方差贡献率达93.20%,反映了所有性状绝大部分信息;根据各品种在各公因子上的得分值,将10个供试品种产量和品质的差异聚为5大类;在各类品种的产量与主要品质性状多元方差分析中探讨其改良目标的针对性.

| Abstract: | Factor analysis was conducted to study 18 quantitative characters of 10 spring cotton varieties of regional test in Henan Province in 2006.The result showed that the cumulative total variance contribution rate of the previous 5 common factors,which reflected most of the characteristic information,to the tested characteristic variation amounted to 93.20%.Five groups had been clustered for the ten tested varieties from the differences in yield and quality according to the scores of the varieties on the common... |
