ABSTRACT:
A new and distinct cultivar of black walnut tree (Juglans nigra L.) which is distinctly characterized by rapid growth rate, strong central stem tendency, and outstanding straightness for timber purposes. The nut-bearing habits of this tree are unknown. It has not borne either pistillate or staminate flowers during the first 7 years after grafting. The strong central stem tendency is due to the ability of the terminal bud to flush and outgrow the laterals. This variety also has good anthracnose resistance. This particular variety was discovered by the applicant near Martinsville, Ind. in a cultivated area. It 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 qualities. This selection has been designated as BW132 in records maintained on the performance of grafts made from the original selection at Purdue University and will be known henceforth as "Purdue 3".
