高寒地区苦荞农艺性状及生产性能评价

为探索不同地区苦荞在高寒地区的农艺性状及生产性能,采用多重比较及聚类分析法分析了7个地区13种苦荞的农艺性状及生产性能。结果表明不同地区苦荞的农艺性状及生产性能差异显著(P0.05),云苦荞2号和晋苦荞2号的农艺性状及生产性能优于其他品种;聚类分析将13个荞麦样品分成2组,在一定程度上体现了荞麦资源的道地性特征,反映了不同苦荞品种的农艺性状及生产性能与亲缘关系之间有一定的联系。

Evaluation on Agronomic Characters and Productivity of F. Tataricum in Alpine Regions

In order to explore the agronomic characters and production performance of F. tataricum from different regions in alpine region, multiple comparison and clustering analysis methods were applied to analyze the agronomic characters and production performance of thirteen kinds of F. tataricum from seven regions. The results showed that the difference of agronomic characters and production performance is remarkable in different regions （ P 〈 0.05 ）. Agronomic characters and production of yun F. tataricum No. 2 and jin F. tataricum No. 2 ware better than the other varieties. Cluster analysis showed that thirteen F. tataricum samples could be classified as two groups, which could identify the genuineness of Fagopyrum resource to some extent. This refected agronomic characters and production performance of different varieties of F. tataricum and their affinity has a certain relationship.
