| Abstract: | Five quantitative traits of Pinus tabulaeformis were of significant difference,with variance component difference also in family,reaching 53%~78%.The difference among DBH,timber volume,seed yield and stem straightness are at significant level.Timber volume and DBH are of close genetic relationship. |
