利用红松在辽宁东部地区两个参试点的生长资料，分别以树高和地径为指标，采用回归分析法、基因型分组法以及生产力指数法对红松生长性状的稳定性进行划分，并将17个产地红松进行分类。红松种内的遗传变异相差很大，树高和地径变异范围分别为2.33%～18.06%及2.91%～16.96%，进行良种选育，能最大限度提高产量。辽宁省草河口镇种子园在树高和地径两项指标中均为高产非稳定型，在环境条件优良的造林生态相似区生长表现良好，故在今后的种子及苗木的调拨中要选择此类林分，大量生产良种，在造林区和生态相似区进行推广应用。

According to the growth records of Pinus koraiensis from two experiment fields in Eastern Liaoning Province of China, seventeen seed sources were divided through regression analysis and genotype grouping and PQI methods.There was large genetic variation within the species of Pinus koraiensis.The genetic variation of tree height and root-collar diameter were 2.33%-18.06%and 2.91%-16.96%respectively.Breeding improved varieties can increase yield maximum.Seed orchard in Caohekou county are high-yielding and unstable type in tree height and root collar. It will make a good job in optimal environment of afforested area and the ar-eas that have similarity ecology.Choose these two seed sources in transfering the seeds and seedlings.Produce more improved varieties in the afforested area and the areas that have similarity ecology.
