Description: Black walnut (Juglans nigra L.) timber varies more in value and quality than any other hardwood species native to the Central States. While much of the quality variation can be attributed to environment, there is little doubt that part of the variation is due to inherent characteristics. In 1961 a study was undertaken by the Central States Forest Experiment Station of the U.S. Forest Service to find black walnut trees that will produce superior seedlings for planting in various regions within the commercial range of the species. This is a one-parent progeny study and the primary criterion for selection is the suitability of the parent tree for the potential production of high-quality veneer. The only other study of black walnut seed source for timber production that we know of was the one begun by Wright in 1945. However, this provenance study has been discontinued due to poor initial survival and growth.
