Based on the determination of the rosin-producing capacity of the open pollination progeny sesting from the high-yield rosin Pinus massoniana Lamb it was observed that the rosin-producing capacity of 75% high-yield rosin P. massoniana Lamb was higher than that of general ones.By genetic analysis among the families of progeny stands, it was discovered that family heritability was 67.48%, genetic variation index 0.745, and genetic plus 68.33%.Through the relative analysis of rosin-producing capacity between t...
