摘　　要：为探索大麦主要农艺性状的遗传规律,提高大麦产量,为云南省大麦品种审定和推广提供科学依据,以14个大麦品种(系)为材料,进行了相关分析和聚类分析。结果表明:14个大麦品种(系)农艺性状存在丰富的遗传变异,7个农艺性状变异程度与范围较大;各农艺性状间存在复杂的相关性,其中有效穗数与产量的相关性最高;供试14个大麦品种(系)可聚为两大类,分别为中矮秆型和中高秆型。In order to explore the genetic laws of the main agronomic traits of barley,improve barley yield,and provide scientific basis for the approval and promotion of barley varieties in Yunnan Province,this paper used 14 barley varieties(lines)as materials for correlation analysis and cluster analysis.The results showed that there were rich genetic variations in the agronomic traits of 14 barley varieties(lines),and the degree and range of variation in 7 agronomic traits were relatively large.There were complex correlations among various agronomic traits,with the highest correlation between effective panicle number and yield.The 14 barley varieties(lines)could be clustered into two categories,namely medium short stem type and medium high stem type.
