What are the main differences between the improved seedlings and the grafted trees?
The grafted trees are genetically identical clones of the parent cultivars described above. The superior seedlings are grown from the nuts of these trees as well as the original Purdue Number One cultivars. As such, the seedlings will vary somewhat from their parent trees but will still possess better genetics than common seedlings. 3. Is the genetically superior walnut tree cultivar really that much better than common seedlings? The forest geneticist who developed the genetically superior trees estimates that only a fraction of 1% of common black walnut seedlings will have the same growth and form characteristics as the genetically superior trees. Even when given the best care, maybe 10% will produce veneer-quality wood, but only after a period of 50-60 years or more. Results from our planting of superior seedlings show that at least 60% should make veneer grade with proper care. Except for those damaged by outside forces (lightning, wind), virtually all of the grafted trees should be
