| 摘 要： | 以粗皮桉种源、家系试验林1～5年生和10年生的树高、胸径的调查数据为基础,进行种源、家系间性状差异性分析,估算出2个性状各个年龄段的遗传力.采用最佳线性无偏预测法(BLUP)估算历年树高、胸径性状的育种值,用最小方差聚类分析法(WARD)对育种值开展种源、家系2个层次的选择分析.结果表明:粗皮桉前5年树高、胸径在家系间... |

| Abstract: | Based on the height(H) and diameter at breast height(DBH) of 1-to 5-year-old and 10-year-old Eucalyptus pellita provenance and family trial forest,the difference of traits in different families and provenance was analyzed.Then the heritabilities of two traits in different years were estimated.Breeding values(BV) for both traits in many years were estimated by Best Linear Unbiased Predict(BLUP),which were used to choose superior provenances and families by the Ward's Minimum Variance Cluster Analysis(WARD).T... |
| Keywords: | Eucalyptus pellita provenance family breeding value best linear unbiased predict |
