Twenty-five different geographic sources of black locust trees from Ohio, Maryland, West Virginia, and Virginia were studied for 3 years in a replicated experiment in Maryland. Significant differences were found in heights, diameters, kiln-dry weights, and susceptibility levels to locust twig borer. None of these variables were related to either longitude or latitiude of the seed source. However, high-elevation sources included more rapidly growing populations than those from low elevations. The third-year sprouts of the most productive source had the kiln-dry weights equivalent to 70,000 kg/ha. This suggests that selected black locust sources may qualify for short-rotation mass yield of energy. The most outstanding in kiln-dry weight per square growth space were some sources from Tucker, Randolph, and Mineral counties of West Virginia. North. J. Appl. For. 7(1):38-43, March 1990.
