为了选择高产脂的思茅松优良家系,对8年生的42个思茅松高产脂优良家系的半同胞及1个对照的产脂力、树高、胸径等进行测定.结果表明,所有家系的产脂力均大于对照,较对照产脂力平均提高达32.9%,家系间产脂力存在极显著差异.产脂力的家系遗传力为0.49.初步选择出3个脂材两用型的思茅松优良家系,其产脂力的实际增益平均为70.2%;选择出2个高产脂的优良家系,其产脂力的平均实际遗传增益为108.8%.
Selection of Half-sib Pinus kesiya var.langbianensis with High-Resin-Yield
In order to select the superior families of Pinus kesiya var.langbianensis with high-resin-yield,the resin-producing capacity,DBH and tree height of 42 high-resin-yield families and a control (8 years old)were measured and analyzed.The results showed that the resin-producing capacity of each family was higher than that of the control,and the average resin-producing capacity was 32.9 %,higher than the control.The results of analysis of variance showed that the resin-producing c apacity among the families had significant differences.The family heritability was 0.49.Three superior families for dual-purpose type for resin and timber were selected,and the realized-gain of resin was 70.2%.Two superior families for high-resin-yield were selected,and the realized-gain of resin was 108.8 %.
