Abstract: Ozark Chinquapin-R is a new and distinct North American Castanea cultivar that is blight-resistant, precocious and a producer of heavy annual crops of one to six nuts per bur. It produces a heavy crop of nuts each year with a small-sized nut containing the highest protein and carbohydrate percent of any chestnut. Nut drop begins around September 10 and continues for a seven-to eight-week period. Most of the nuts produced drop in the first five weeks of the period of nut drop from this cultivar. Ozark Chinquapin-R is a medium-sized tree that has an elliptic-shaped canopy with high upright to spreading and diffuse lateral branches. This nine-year-old cultivar is 7.92 meters tall with a canopy covering an area 21.22 square meters. Its heavy nut crop occurs from early September through mid-November, providing the highest protein and carbohydrate nut crop of any chestnut for people and wildlife.

Abstract: A new and distinct Corylus plant named ‘PollyO’ is characterized by high nut yield, early nut maturity, small round nuts and kernels, high kernel percentage, good kernel blanching and excellent flavor. The tree is vigorous and has a desirable growth habit. ‘PollyO’ is resistant to bud mite (primarily Phytoptus avellanae Nal.). DNA markers and field exposure indicate that it is highly resistant to eastern filbert blight (EFB) caused by Anisogramma anomala (Peck) E. Müller.
