    A hybrid pine developed in the course of forest-tree improvement research. by the U. S. Forest Service has caught the interest of Christmas tree growers. It is a hybrid between two races of lodgepole pine (Pinus contorta) produced at the Institute of Forest Genetics at Placerville, California, and has some desirable attributes for use as a Christmas tree: good form and color, relatively rapid growth, and early production of persistent cones.
