摘要:
选择优良家系及单株作为营建浙江楠种子园的亲本以及现有种子园管理依据,可以实现种子园高产稳产,提高种子园遗传品质以及遗传增益。通过对庆元县实验林场营建浙江楠实生苗种子园8年生43个家系的生长性状和结实性状调查,经方差分析、遗传力估算及聚类分析表明,43个家系的各性状在家系间均存在显著或极显著差异,各性状平均变异系数为8.88%—18.48%,家系遗传力0.45—0.73,单株遗传力0.14—0.55。相关分析表明生长性状间均存在极显著正相关;经聚类分析可将群体分为4个类群,其中类群2和类群3中家系具有更优的生长与结实表现,研究结果将为浙江楠实生苗种子园疏伐改造及新一代种子园营建提供科学依据。
Abstract:
By selecting the elite provances and single strain of Phoebe chekiangensis as parents,the seed orchard could be erected to achieve high and stable yield, improve genetic quality and genetic gain. In this article, the growth and fruiting traits of 43 provances of the aged 8 P. chekiangensis in seed orchard, Qingyuan Experimental Forest Farm, were investigated. The results of their variance analysis, heritability estimation and cluster analysis showed a significant differences among these provances. The coefficient of variation of each character ranged from 8.88% to 18.48%. The provance heritability was between 0.45 to 0.73, and individual heritability was between 0.14 to 0.55. Correlation analysis showed a significant positive correlation between growth traits. Through cluster analysis, they could be divided into four groups, in which Group 2 and Group 3 had better growth and seed setting performance.
