湿地松半同胞家系苗期选择的研究

摘要

以46个湿地松半同胞家系为研究对象，对其1年生苗木的苗高和地径生长进行了测定与分析，旨在选择表现良好的半同胞家系。结果表明：家系间苗木的苗高和地径生长差异极显著。综合苗高和地径性状，初步选择出0-1027、4-12、0-464、7-258、0-510、Ⅳ-9等6个表现良好的家系。%By taking 46 half-sib families of Pinus elliottii as the studying objects, the seedling height and basal diameter of one-year-old P. elliottii were investigated and studied in order to select the excellent half-sib families. The results show that there were significant differences in seedling height and basal diameter among the families. According to the characters of seedling height and basal diameter, 0-1027, 4-12, 0-464, 7-258, 0-510Ⅳ-9 families were selected as the superior families.
