摘　　要：对参加全国2005年春棉区试(A组)的13个品种,包括植株、产量和纤维品质共22个数量性状进行因子分析结果表明,前6个公因子对所考察性状变异的累计方差贡献率达89.24%,反映了所考查性状的绝大部分变异信息,根据各品种在各公因子上的得分值,将13个供试品种从产量和品质的差异聚为5大类。图1,表4,参8。Factor analysis method was applied to study 22 characteristics indexes of 13 varieties from the spring cotton zones in all of the county in 2005, with cotton plant , yield and fiber quality in all included. The result showed that the cumulative total variance rate of the previous 6 common factors, which reflected most of the characteristic information, to the tested characteristic varieties amounted to 89.24%. Five groups had been clustered of the thirteen tested varieties from the differences in yield and quality according to the scores of the varieties on the common factors, respectively.
