24 clones of 3 families of Pinus elliottii var. elliottii×P. caribaea var. hondurensis (PEE×PCH) were propagated by cutting. Rooted cuttings of these clones were planted in one site in Taishan, Guangdong. And seedlings of PEE and PCH were planted in the test for checking. Growth traits in the 6.5yearold clone test were determined and analyzed. The results showed that 体育博彩平台排名 factors and non体育博彩平台排名 factors were nearly equally significant to control the expression of growth traits. And family variance is larger than clone variance among the 体育博彩平台排名 variance. Estimates of family mean heritability were 0.967, 0.889, 0.942, respectively, for height, diameter at breast(DBH), and stem volume. Estimates of clone mean heritability within fullsib families were 0.674, 0.829, and 0.799, for the above traits, respectively. The average values of all clones for height, DBH, and volume were 8.76 m, 13.85 cm, 0.070 49 m3, respectively. The real gain for volume was 199.68% compared to PEE, and 24.18% compared to PCH. Nine clones were selected among the 24 tested clones, for their fast growing rate. Their average increment was 9.00 m， 14.94 cm， 0.081 69 m3, respectively, for height, DBH, and volume. Expected 体育博彩平台排名 gains of five best clones were 0.66%～13.56% for height, 5.15%～10.96% for DBH, and 9.22%～34.02% for volume.
