摘　　要：为了选择思茅松优良家系,对半年生9个家系和1个对照的造林苗木进行树高、地径观测。结果表明,所有家系的树高生长量和地径生长量均大于对照。方差分析结果表明,家系间树高生长量和地径生长量均存在极显著差异。树高生长量与对照相比,有7个家系差异达到极显著水平;地径生长量与对照相比,有8个家系差异达到极显著水平。In order to select the superior families of Pinus kesiya, this research studied the tree heights and ground diameters of 9 half-year-old families and 1 tester of seedlings. The results showed that the in- crements of heights and diameters of 9 families surpassed that of the tester. Variance analysis indicated that the increments of heights and diameters of families differed greatly, among which the difference of height increments of 7 families and the difference of diameter increments of 8 families were extremely sig- nificant.
