In this study, the heritability and genetic correlation of the contents of Pinus elliottii turpentine and its five components were estimated by measuring the resin composition. The Smith-Hazel comprehensive selection index was used for evaluating the turpentine composition of 186 high-yielding slash pine trees, and the high-yielding and good-quality P. elliottii plus trees were selected into the seed orchard by "core-master group" breeding system. The results showed that the family heritability and individual heritability of turpentine and its component content of P. elliottii were 0.3402-0.5713 and 0.2112-0.4773, respectively, indicating that the variation in turpentine and its component contents of P. elliottii were controlled genetically at medium level. 7 plus trees with high turpentine(the genetic gain was 51.57%) and high β-pinene(the genetic gain was 97.89%) were selected as the core-breeding population, and 86 plus trees were selected as the master-breeding population as the genetic gain of turpentine, α-pinene, camphene, β-pinene, dipentene, and myrcene were 14.70%, 4.22%, 10.26%, 22.99%, 17.69% and 13.49%. respectively.
