1980年,在福建省的7个地区47个县101个林分中,选出786株优树,采集自由授粉种子。在福建省洋口等六个林场建立子代测定林1000余亩。7年生时测量了树高等6个性状。根据树高值统计结果表明。大于遗传对照10％以上的家系有293个,占参试总数的49％,树高单株遗传力h_1~2=0.24,家系遗传力h_1~2=0.32;树高生长量的遗传分析表明,群体的变异量大于群体内个体的变异量,变异来源是多层次的。
In 1980, out of 101 stands in 47 counties in 7 districts and districts of Fujian Province, 786 excellent trees were selected and free pollinated seeds were collected. The establishment of offspring measuring more than 1000 acres in six forest farms in Yangkou, Fujian Province. Six traits of tree height were measured at 7 years old. According to the tree height statistics show. 293 were more than 10% of the genetic control, accounting for 49% of the total. The heritability of tree height per plant was h_1 ~ 2 = 0.24, and the heritability of pedigree was h_1 ~ 2 = 0.32. Genetic analysis of tree height growth showed that, The amount of variation in a group is greater than the amount of variation in an individual in a group, and the source of variation is multi-level.
