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 %.
