利用14个啤酒用二棱皮大麦品种的八个产量性状资料,根据其表现型的相似性,用群分析“Q”法对品种材料进行归类,并计算各品种之间所有能成对的距离系数。聚类开始,以两个关系密切的品种聚为一组,随后不断将相似水平最大组的品种聚合,直至最后所有品种都聚在单一的一个组内。聚类结果:14个品种可分为2群、4类,类下又分为5组,又利用8个产量性状资料,根据其表现型相似性用群分析“R”法对比分类,也计算各品种间的所有可能成对的相关系数。聚类结果:14个品种可绘成直观的主穗结构和产量结果的谱系图。81原306是有希望的啤酒用二棱皮大麦,已确定参加全国北方和省内区域试验。
Based on the similarity of the phenotypic traits, 14 varieties of barley from Ergophyllum cv. Barley were used to classify the cultivars by the method of cluster analysis and all the pairs The distance coefficient. Clustering begins with a group of two closely related cultivars, then continuously aggregates the largest group of similar levels until all varieties are grouped together in a single group. The clustering results: 14 cultivars could be divided into 2 groups and 4 groups, which were further divided into 5 groups, and 8 yield traits data were also used to classify them according to their phenotypic similarities using group analysis "R Also calculated for all breeds may be all pairs of correlation coefficient. Cluster Results: Fourteen cultivars can be plotted as an intuitive lineage plot of the main spike structure and yield results. 81 Original 306 is a promising beer with two-sided barley, has been identified to participate in the national test of the northern and provincial regions.
