摘　　要：对云南元谋地区引进试种的22份藜麦材料的农艺性状及营养品质进行相关性、主成分及聚类分析。结果表明,22份藜麦材料的变异系数为18.87%~28.91%,农艺性状变异丰富;产量与主穗长和单株产量呈极显著正相关(P<0.01),与茎粗和叶长等呈显著正相关(P<0.05),与千粒重呈负相关;主成分分析提取到4个主成分,累计贡献率达75.807%;通过聚类分析将22份材料分为3个类群,其中类群Ⅲ表现为高秆、大粒和高脂肪含量,具有利用潜质。筛选出7份(大粒材料LQ09、LQ17、Q24,粗茎材料LQ09、LQ10,高产量材料LQ21、LQ24、Q24和高蛋白含量材料LQ02、LQ17)具有突出特点的藜麦资源。A total of 22 quinoa materials introduced for trial planting in the Yuanmou area of Yunnan Province were analyzed using correlation analysis,principal component analysis,and cluster analysis.The results showed that the coefficients of variation of 22 quinoa materials ranged from 18.87%to 28.91%,and the variation of agronomic traits was abundant.The yield was significant positively correlated with main panicle length and yield per plant(P<0.01),positively correlated with stem diameter and leaf length(P<0.05),and negatively correlated with 1000-grain weight.Four principal components were extracted by principal component analysis,and the cumulative contribution rate was 75.807%;The 22 germplasms were classified into three groups by cluster analysis.Among them,GroupⅢshowed high culm,large grain,and high fat content,which had potential for screening and utilization.Seven quinoa germplasms with outstanding traits were selected(large-grain materials LQ09,LQ17 and Q24,large-stem materials LQ09 and LQ10,high-yield materials LQ21,LQ24 and Q24,and high-protein materials LQ02 and LQ17).
