摘要
以 30个白榆半同胞家系为对象进行家系选择研究 ,经过 10年的田间测试结果表明 ,82 0 6 2、82 0 0 3、730 0 4、82 0 0 5、82 0 4 8五个家系表现优良 ,其胸径、树高、材积生长量均与对照差异极显著或显著 ,5个家系材积生长遗传增益为 4 6 .94 %～ 30 .74 %。
Research on family selection at the base of half-sib Ulmus Pumila families was done in field test for ten years. the results showed five families of 82062,82003,73004,82005,82048 performed better. The growth of diameter, height and volume of five families were greatly superior to the control, the genetic gains of volume growth were 46.94%～30.74% in five families.
