摘　　要：从美国引进三代湿地松种子园半同胞家系种子和全同胞家系种子,开展育苗试验,对其苗高和地径生长进行了测定分析与比较,结果表明:湿地松半同胞与全同胞家系间苗高与地径生长均存在显著差异,结合苗高与地径生长性状,通过Duncan法筛选出湿地松半同胞家系S8、S5、S25、S7、S3、S16、S22为苗期生长性状优良的家系,湿地松全同胞家系S21、S17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 ofhalf-sib and full-sib families of Pinus elliottii were studied whose seeds were imported from United States. The results showed that： There were significant differences in seeding height and basal diameter among half-sib and full-sib families of Pinus elliottii. According to Duncan＇s contrast, S8, S5, S25, S7, S3, S16, S22 were selected for the optimal halfsib families, and S21, S17 were selected for the optimal full-sib families. There were obvious advantages in seedling growth of Pinus elliottii which were imported from United States.
