Current status: Sugar Pine (Pinus lambertiana) is a species from the Genus: Pinus but is of a subgenus: Strobus. This is mainly attributed to the fact that Sugar pine trees are soft pine trees. Earlier comparative mapping was carried out with the Sugar pine genetic maps having the ESTP markers (Garth et al. 2001).
More recent work regarding the creation of genetic maps for Sugar pine have the SNP markers incorporated into them. Kathleen Jermstad (IFGR-Placerville, CA) has created the Sugar pine genetic map using three mapping populations, namely- Tree 5701, Tree 6000 and a QTL sex-averaged population.
