Seed was collected in 1964 from 100 wind-pollinated Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) parent trees from four sites, two near Corvallis, Oregon, and two near Shelton, Washington. By 1974, eight commercial Christmas tree growers in Oregon and Washington had cultured, harvested, and marketed progenies grown in designed tests. Financial returns on progenies of the 10 best parents showed discounted gains of 18 percent in selling price but net returns were increased 58 percent because rapid growth was a major factor in profitability. Upright branching and dense, dark foliage contributed most to upgrading the trees. Seedlings from top-ranking parents are in commercial production, and second-generation breeding has begun.
