| 摘 要： | 对收集的云南松（Ｐｉｎｕｓ ｙｕｎｎａｎｅｎｓｉｓ）２９２个半同胞家系进行栽培试验，经方差分析知各家系子代间高生长有极显著差异，真正的优树占参试总数的２９．７％（广西）；树高广义遗传力为５８．０％，遗传增益为３８．８９％；同一林分内家系间高生长变异幅度小于林分之间的变异幅度。

| Abstract: | This paper deals with the cultivation experiment on the progenies of 292 maternal families of Pinus yunnanensis Franch. The analysis of variance among all above was carried out. The results showed that the growth was very remarkable, and 29.7% of the good tree was selected from our testing. About 58% of genetic force of height growth was obtained and the genetic gain was 38.89%. The variable range of height growth among families from the same standing forest was much less than the different stand one. |
