Genetic Mapping In Loblolly Pine

A consensus map for loblolly pine (Pinus taeda L.) was constructed using restriction fragment length polymorphisms (RFLPs) as genetic markers. This map is based on segregation data from two unrelated three-generation pedigrees (Devey et al., 1994; Groover et al., 1994) and was assembled using the linkage computer program JoinMap (Stam, 1993). The merger of individual genetic maps into a consensus map for loblolly pine allows for the integration of genetic information from independent sources onto a single map and facilitates the consolidation of linkage groups to represent the 12 chromosomes of loblolly pine. This consensus map contains many known and characterized genes, and serves as the foundation for present and future genetic studies in loblolly pine and for studies of genome organization and evolution in conifers. Keywords: Pinus taeda L., genetic mapping, RFLP molecular markers, genome organization.
