赤桉家系的抗风性状与选择

摘要

Family pedigree quality and individual wind resistance genetic values of one-year-old Eucalyptus camaldulensis family were estimated and evaluated by using BLUP model method. Through variance analysis, the results show that there were obvious signiifcant differences in growth of tree height (H) and ground diameter(D) and crown(C) and wind damage index(I) among E. camaldulensis family;There were a lot of differences in family heritability and there was little difference in individual heritability in annual. At last the ifne families were evaluated and selected out according to the family ranking scores based on the estimated data from the BLUP model method.%运用BLUP模型对一年生赤桉家系进行家系和个体抗风遗传值评估和筛选。结果表明：一年生赤桉自由授粉家系在树高、地径、冠幅、风害指标上存在显著的差异。不同家系的家系遗传力之间差异不明显。单株遗传力差异不明显。根据BLUP分析获得赤桉家系评估，利用排名得分，选出优良家系。
