Genetic Variance of the Third Generation of Pinus taeda Half-sib Families and P. taeda × P. caribaea Hybrid
()
Abstract:
In this study,the third generation half-sib families of the loblolly pine (Pinus taeda) and full-sib families of P. taeda× P. caribaea were selected as the research object. Nine third generation open-pollinated families of loblolly pine and eleven hybrid families of loblolly pine by P.caribaea were studied for growth traits at the age of 2 years and 5 years. Mixed seed from Taishan P. elliottii improved seed orchard were used as control (CK1). The main results were as follows: (1) Compared with CK1, both hybrid pine families and P. taeda third generation half-sib families held advantage in growth. (2) No significant difference was found between hybrid pine and third generation half-sib families of P. taeda. (3) Superior families were selected based on 5-year-old means single tree volume, including 09-15, 09-9 and 44-12-5, 26- Ⅲ -4.
Key words:  Pinus taeda ; P. taeda×P. caribaea; genetic variation; superior families
