| 摘 要： | 以四川省富顺县国营林场马尾松初级种子园58个半同胞家系子代为研究对象,在四川富顺国营林场开展苗期试验,测定6月龄苗期苗高、地径和冠幅3个性状.采用方差分析、遗传力估算、相关分析等方法对测定数据进行统计分析.结果表明:马尾松家系间苗高、地径和冠幅等生长性状均达极显著差异,表明马尾松半同胞家系间存在较为丰富的变异,选育潜力较大;苗高、地径和冠幅3个性状遗传力较高,属强度遗传;苗高、地径和冠幅三个性状之间呈显著正相关,尤以苗高与地径相关密切;以苗高、地径2个主要苗期生长性状,选出6个苗期生长较快的家系.

| Abstract: | Studies were made of the open pollinated seeds of 58 Pinus massoniana families from the seed orchard in Fushun Forest Farm in Sichuan Province.Seedling cultivation was done with complete random block design.The data of height,ground diameter and crown width of six-month-old seedlings were analyzed by variance analysis,heritability evaluation and correlation analysis.The results showed that the differences in these growing characters were significant among families.It was indicated that the improvement poten... |
