Correlation Analysis of Elm Tree Leaf Characters Variation and the SSR Markers
This experiment collected 40 Elm clones from Zhangjiakou City Dragon Mountain Region as experimental material.In this research,we analyzed the leaf shape traits and SSR molecular markers.The results showed that,15 leaf traits had a significant variation between 40 Elm clones;Most the repeatability of the leaf shape index is above 0.8.Use 15 leaf shape index to 40 elm clones for clustering analysis,40 Elm clones could be divided into 4 kinds,the genetic distance of each clone was between 0.578～9.309.Use 13 pairs high polymorphic SSR primers selected from 17 primers to 40 elm clones for clustering analysis,the genetic distance of each clone was between 0.030～0.664.15 leaf traits and SSR molecular markers achieve significant correlation,the correlation coefficient was 0.473 8 (p＜0.001,n=780,rα=0.118).This showed that leaf shape traits had high level associated with selected SSR loci.
