本文研究未知产量品系苗期产量预测方法的准确度,试验结果如下:“小叶柄胶法”:高产品系的选对率达77.8%; 低产品系的误选率为4.7%;3～6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=72,r=0.6521**).“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**).
In this paper, we studied the accuracy of the seed yield prediction method of unknown yield lines. The test results are as follows: “Petiole Glue Method”: the selection rate of high yielding lines was 77.8%; the false selection rate of low yielding lines was 4.7%; 3 ~ 6 There was a significant correlation between the petiole glue value and the average annual yield of three-year cutting of the adult shoots (n = 72, r = 0.6521 **). “Vein gel method” 63.6%; the false selection rate of low-yielding products was 8%; there was also a significant correlation between the veins gum grade of the third-instar young tree and the average annual yield of the three-year cuttings of adult buds (n = 42, r = 0.5218 **) .
