USDA 61-1-X was developed by crossing Barton with Starking Hardy Giant. The nut is medium sized (6.5 g/nut) and produces an average of 57% kernel. Flowering is protandrous. If this cultivar proves to be scab resistant like its Barton parent, USDA 61-1-X may be just what we are looking for to pollinate the scab-resistant, protogynous cultivars Kanza and Lakota. USDA 61-1-X ripens early, about the same time as Colby. Both Barton and Starking Hardy Giant have strong alternate bearing tendencies so we will need to watch this USDA cultivar over time to see if alternate bearing develops.
