![]() ![]() The forest geneticist who developed the genetically superior trees estimates that only a fraction of 1% of seedlings from common black walnut trees will have the same growth and form characteristics as the genetically superior trees. Is the genetically superior walnut tree cultivar really that much better than common seedlings?.As such, the seedlings will vary somewhat from their parent trees but will still possess better genetics than common seedlings. The superior seedlings are grown from the nuts of these trees as well as the original Purdue Number One cultivars. The grafted trees are genetically identical clones of the parent cultivars described above. What are the main differences between the improved seedlings and the grafted trees?.The two most famous cultivars patented by the university are Purdue Number One and Tippecanoe Number One. Increased growth rate, vigor and vitality have been developed while maintaining superior form. Over the years, through genetic selection of successive generations, trees with ![]() Through a selection process using form and growth rate as criteria, the geneticist determined the most superior trees. Originally, scion wood, or bud wood, was collected from over 400 black walnut trees throughout the Midwest that had superior form. These trees are the result of decades of research by a forest geneticist from a leading Midwestern university. What are genetically superior black walnut trees?.USDA Zones 4-8 NOTE - Tree seedlings, grafts and planting expenses are tax deductible-up to $10,000 per year (For more information visit Black Walnut Questions & Answers ![]()
