Hardwood Tree Improvement To Date And Tomorrow

Sycamore, sweetgum, black walnut, cottonwood, yellow-poplar and eucalyptus have been planted in commercial size plantations in the Southern U.S. These species and 35 more are under some degree of tree improvement research with very small seed orchards established for 15 species. Limited research funds dictate a challenge to systematically analyze for prediction of future tree improvement needs with selected hardwood species. Twenty-nine institutions are doing some study of tree improvement research with hardwoods. Additional keywords: Genetics, planting, superior tree selection.
