| Abstract: | Cluster analysis was conducted to study on the DBH, height, crown width and current increment of height of Larix kaempferi seed trees in clone seed orchard by using K-means. The results indicate that Longping, Mengren,Tumen Mountain,Heiqing Mountain and Maoer Mountain are excellent provenances and 27,30,33,97, 102,115,117,118,119,121,122,5,32,95,98,102,111,112,113,125 in Longping,1,2,3,4,5,6,7,8,9,12, 13,15,16,18,20 in Mengren,1,2,4,9,10,11 in Tumen Mountain,1,2,3,5,6,7,9,12,14,15,16,20 in Heiqing Mountain,3,4,6,9,10 in Maoer Mountain are excellent clones. |
