Black walnut tree

Abstract

A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by outstanding nut qualities, such as abundant annual crops of average-sized nuts, begins nut-bearing very early in life of tree, averages 4 nuts per cluster, and produces kernels which exceed about fifteen (15) percent of nut weight. The nuts are medium-sized and ripen mid-season. The new variety is very late in time of leafing and has excellent walnut anthracnose resistance. The pistillate flowers mature very late and pollen maturity is late. In most years there is little overlap in female and male flowering. This variety has fairly slow growth and poor straightness. Flowering begins very early in the life of the tree. This new variety of black walnut tree was discovered by the applicant near Bentonville in Fayette County, Ind., in a cultivated area. In occurred as a wild tree growing on land managed for timber-growing purposes and was discovered in the course of a search for unique and high quality black walnut trees to be utilized in breeding for outstanding timber producing potential. This selection has been designated as BW13 in records maintained on the performance of grafts made from the original selection and will be known henceforth as Fayette-2.
