22个冬小麦品种主要农艺性状相关性及聚类分析OA

In order to scientifically and reasonably utilize wheat germplasm resources and achieve the goal of improving wheat varieties,this study used a combination of field observation and indoor seed testing to conduct correlation analysis and cluster analysis on main agronomic traits of 22 winter wheat varieties. The results showed that 22 winter wheat varieties could be divided into two groups. The correlation coefficients between yield and basic seedlings,highest number of tillers and effective panicles were 0.740,0.771 and 0.617,respectively,reaching a highly significant level. These three factors played a key role in wheat yield. Therefore,in the process of variety selection,different types of germplasm resources could be selected for the formulation of hybrid combinations.
