According to a recent IBISWorld report, over 1.5 billion trees are produced and shipped annually in the United States. States within the Great Lakes Region (plus Kentucky and Tennessee) annually plant over 60 million trees from forest product nurseries (55 percent), private nurseries (22 percent), and state nurseries (21 percent). This market opportunity represents approximately $360 million in tree seedling/graft sales for this region. Currently, most private nurseries randomly collect seeds for seedling production with no regard to tree form or growth characteristics. Therefore, there is a great opportunity to improve quality of selected tree seedlings and grafts.

Researchers at Purdue University have provided improved genetics of the available black walnut trees for investment and quality purposes. Samples were collected from over 400 of the best specimens throughout the United States and have been bred through each rotation. Only the trees in the top five percent go on to the next generation; a one to three percent increase is expected every five years. These genetically superior trees will grow straighter, faster, and with less epitomic branches, resulting in a final product with higher quality marketable timber in less time. These results increase the chances for obtaining veneer grade lumber and high-quality trees desirable for landscaping.

There are multiple varieties of black walnut trees available.

-Trees will grow straighter, faster, and with less epitomic branches.
-Higher quality marketable timber in less time
-Improved aesthetics of trees desirable for landscaping

Potential Applications:
-Tree Production
-Tree Seedling/Graft Sales
