Distinct variety of black walnut tree

Abstract

A new and distinct variety of black walnut tree (Juglans nigra L.) which is characterized by rapid growth rate, strong central stem tendency, and outstanding straightness for timber purposes. The nut-bearing habits of this tree are inferior. The pistillate flowers mature very late while pollen maturity is fairly late. In most years there is no overlap in female and male flowering. Flowering begins very late in the life of the tree. The nuts are large and ripen in mid-season. Nut crops occur rarely and are very light. This new cultivar of black walnut tree was discovered by the applicant in Carroll County near Camden, 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. The original tree was cut and sold for high quality veneer. This selection has been designated as BW68 in records maintained on the performance of grafts made from the original selection at Purdue University and will be known henceforth as "Purdue 2".

What is claimed is: 
     
       1. A new and distinct variety of black walnut tree substantially as illustrated and described, which has excellent timber quality, is fast growing, has strong central stem tendency, little sweep, few crooks; late in time of leafing, pistillate flowers very late, pollen sheds late, and a nut crop is seldom produced.
