Greatwoods: Genetically Superior Hardwoods
Researchers at Purdue University have developed several new walnut varieties (Greatwoods) that reduce variation in growth rate and tree form. Greatwoods have higher growth rates, better timber quality, and a stronger resistance to disease than any clones currently available. Black walnuts are not the only improved species being developed. The goal of the Hardwood Tree Improvement and Regeneration Center (HTIRC) at Purdue is to improve the genetic quality and regeneration of fine hardwoods, including black walnut, black cherry, butternut, northern red oak, white oak, and American chestnut, through application of classical breeding, genomics, molecular markers, genetic modification, advanced propagation and seed production technologies, and silviculture. Greatwoods are the product of decades of research and testing that have created trees that are more resilient and profitable.
