摘　　要：选取了49份甜糯玉米杂交新组合和苏玉糯5号为试验材料,对其产量和品质等16个性状进行了主成分分析和聚类分析。通过主成分分析将16个性状降为5个主成分,这5个主成分能解释表型变异的89.42%。对5个主成分进行二维排序分析和聚类分析,共筛选到9个优异甜糯玉米杂交组合,为甜糯玉米新杂交组合的选育提供了科学依据。The 16 yield and quality indexes of 49 sweet waxy maize new combinations and Suyunuo No.5 were evaluated by using principal component analysis and cluster analysis.The principal component analysis reduced these 16 traits to 5 principal components,which could explain 89.42%of phenotypic variations.Through two dimensional sorting and cluster analysis of these 5 principal components,9 excellent sweet waxy maize hybrid combinations were screened out.These results can provide a scientific basis for the hybrid breeding of sweet waxy maize.
