采用苗期产量预测方法对未知产量品系的3龄胶树进行产量预测,结果如下: 用“小叶柄胶法”,高产品系的选对率达80%,低产品系的误选率为10%;3龄幼树小叶柄胶值与其成龄芽接树头三割年平均产量之间呈极显著相关(n=42,r=0.5559~**)。用“叶脉胶法”,高产品系的选对率为63.6%,低产品系的误选率为8%;3龄幼树叶脉胶等级与其成龄芽接树头三割年平均产量之间亦呈极显著相关(n=42,r=0.5218~(**))。

The seed yield prediction method was used to predict the yield of 3-day-old ginkgo trees with unknown yield. The results were as follows: The selection rate of high-yield lines was 80% and the false-selection rate of low-yield lines was 10 %. The results showed that there was a significant correlation between the plasticity of the petiole and the average annual yield of the three-year cuttings of its adult buds (n = 42, r = 0.5559 ~ **). With “Vein gel method”, the selection rate of high-yielding lines was 63.6%, and that of low-yielding lines was 8%. The average age of three-year-old leaves was Was significantly correlated (n = 42, r = 0.5218 ~ (**)).
