通过高产脂马尾松初级种子园产脂力测定 ,结果表明 :14个 3重复和 19个 2重复无性系间的差异都达到极显著性水平。无性系平均重复力为 79 3%～ 86 4 % ,遗传增益为 6 6 9%～ 86 1%。对 6 1个无性系 10 8个幼年期单株产脂力调查 ,发现有 14个单株产脂力特别高 ,其中有 3个单株 10cm割沟单刀产脂量超过 2 0g ,有 8个单株 10cm割沟单刀产脂量超过 10 g。
The results showed that the differences between 14 3-repeat and 19 2-repeat clones reached extremely significant level. The average repeatability of clones was 79.3% ~ 86.4%, and the genetic gain was 66.9% ~ 86.1%. In a survey of the fat production of 108 adolescent individuals of 61 clones, it was found that 14 individuals had particularly high lipid yield, of which 3 individuals had a fat yield of 10 cm Single plant 10cm cut ditch knife production fat more than 10 g.
