摘　　要：对美国湿地松三代种子园半同胞家系种子开展育苗试验,测定其苗高和地径生长,结果表明:湿地松半同胞间苗高与地径生长均存在显著差异。结合苗高与地径生长表现,通过Duncan法筛选出湿地松半同胞家系S9、S8、S5、S25、S16、S3、S7、S22为苗期生长性状优良的家系,从美国引进的湿地松家系苗期生长优势明显。Seedling height and basal diameter of half-sib families of Pinus elliottii were studied whose seeds were impor-ted from United States.The results showed that,there were significant differences in seeding height and basal diameter a-mong half-sib families of Pinus elliottii.According to Duncan’s contrast,S9,S8,S5,S25,S16,S3,S7,S22 were selected for the optimal.There were obvious advantages in seedling growth of Pinus elliottii which were imported from U-nited States.
