| 摘 要： | 对从四川省引进的52株墨西哥柏优树自由授粉种子子代进行了单点测定。结果表明：树高、胸径均大于群体平均值5％以上的共有9个家系，以20％的入选率，遗传增益分别为16.7%和41.4%；各家系的生长差异受遗传控制的同时，也受立地条件的影响；苗高与幼林树高存在一定的相关性。

| Abstract: | Progeny tests were made in 52 open-pollinated trees of Cupressus lusitanica .The result showed that 9 families exceeded the mean by 5% in height and DBH.By 20% sellection proportion,the genetic gain was 16.7% and 41.4% respectively,the growth trait was contolled by genetics and environment at the same time,and the seedling height had certain correlation with height of the young trees. |
