Heredity Analysis for Taxane Content from Natural Taxus wallichiana Forest and Tts Cottage Seedlings

WANG Da-ming1,ZHOU Yun1,ZHANG Yu-nong1,WANG Wei-bin2(1.Yunnan Acadmy of Forestry,Kunming 650204,Yunnan,China;2.Forest Department of Yunnan Province,Kunming 650224,Yunnan,China)  
We carried out correction analysis of 6 types of taxane content from 52 natural mother trees of Taxus wallichiana and their clone of cottage seedlings in Yunnan.The correlation coefficient r was 0.556 0 for taxane content among single trees,that of it was 0.896 7 by the trees grouped by altitude,both correlation coefficient reached extreme significant level(α=0.01).We calculated the broad hereditary capacity of this characteristics as H2 = 0.81 which transmitted from mother trees and their clones.Taking the taxane content of above these 52 trees as criterion,13 trees were screened out as excellent tree of high content of taxane.The discrepancy among these excellent trees was 0.320 g/kg.And,the taxance content from their clones increased 0.251 g/kg,the actual hereditary capacity was hr2=0.78.We thus concluded that the hereditary capacity of taxane content was relatively high transferred from mother trees to their clones.
