摘　　要：通过对苗龄为107d的25个思茅松半同胞家系和1个生产混合种的苗木进行子代测定,以地径和苗高为测定依据,筛选出了Ⅰ-9、Ⅱ-4、Ⅱ-8和Ⅱ-9家系的平均地径和苗高均大于生产ck的,筛选出了Ⅰ-9、Ⅰ-11、Ⅰ-13、Ⅱ-2、Ⅱ-4、Ⅱ-8、Ⅱ-9、Ⅱ-12和Ⅲ-16家系和生产ck的平均地径和苗高均大于等于总平均地径和苗高的思茅松。The progeny of 25 Pinus kesiya var.langbianensis half-sib progeny and CK were determined by seedling age 107d.Based on the ground diameter and seedling height,Ⅰ-9,Ⅱ-4 and Ⅱ-8 were selected.The average ground diameter and seedling height of the Ⅱ-9 family were higher than those of the production ck,and Ⅰ-9,Ⅰ-11,Ⅰ-13,Ⅱ-2,Ⅱ-4,Ⅱ-8,Ⅱ-9,Ⅱ-were screened out.The average ground diameter and seedling height of the 12 and Ⅲ-16 families and production CK are greater than or equal to the total average ground diameter and seedling height.
