摘要
通过对５３０株油松优树子代林内８２９个家系（次）生长量的测定，初步选出了较为优良的油松家系，并对不同来源的优树家系和单株的树高及地径的遗传率进行了估算。
By determing growth of 829 families from 530 dominant tree progeny stands of Pinus tabulaeformis, this study have selected primarily some better families and estimated genetic ratio of tree height and basal diameter for dominant tree families and single tree its seed come from differen source.
