云南省14个大麦品种(系)主要农艺性状分析OA

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.
