摘要
通过对 13 年生 37 个红皮云杉家系的 5 个生长性状指标进行遗传变异分析,选择红皮云杉优良家系.根据家系树高及胸径综合选择指数、育种值及整齐度等配合筛选出 4 个优良家系,树高和胸径遗传增益达到 9.35%、8.38%,现实增益达到 11.98%、12.59%,可为鄂西地区红皮云杉种子园建园及无性系造林推广应用提供优质种质材料.
Abstract
By evaluating the genetic architecture of growth and branch relevant traits from 37 13-year-old Picea koraiensis families,we aim to select and breed elite trees for local quality reforestation.4 elite families were chosen by comprehensive selection index,breeding value and neatness with the genetic gain of tree height and breast diameter 9.35%and 8.38%,which could provide quality germplasm materials for the establishment of Picea koraiensis seed orchard and the promotion of clonal afforestation application in western Hubei.
