摘　　要：为了探究加甜型糯玉米主要农艺性状及产量的关系,筛选出综合表现优良的加甜型糯玉米品系,对60个加甜型糯玉米杂交组合的主要农艺性状和产量进行了变异分析、相关性分析、灰色关联度分析、主成分分析和聚类分析。结果表明:秃尖长的变异系数最大,穗长的变异系数最小;相关性分析表明,穗长和行粒数对产量的影响较大;灰色关联度分析结果表明,行粒数和穗长与产量的关联度相对较大;主成分分析将13个性状简化为5个因子,累计贡献率达75.234%;通过聚类分析可初步筛选出3份具有优良特性的潜力材料。In order to explore the relationship between the main agronomic traits and yield of sweet waxy corn,and to screen out the sweet waxy corn lines with good comprehensive performance,variation analysis,correlation analysis,grey correlation analysis,principal component analysis and cluster analysis were carried out on the main agronomic traits and yield of 60 sweet waxy corn crosses.The results showed that the coefficient of variation of bald tip length was the largest,while the coefficient of variation of ear length was the smallest.Correlation analy⁃sis showed that ear length and grains per row had great influence on yield.The results of grey correlation analy⁃sis showed that grains per row and ear length were relatively correlated with yield.Principal component analysis simplified the 13 traits into five factors,and the cumulative contribution rate reached 75.234%.Three potential materials with excellent properties could be selected by cluster analysis.
