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 veneer grade if given proper care.
