Breeding programs at Rutgers University in New Jersey, USDA in Kearneysville, West Virginia, and USDA in Byron, Georgia, along with private programs in California and Michigan have produced a number of new cultivars in recent years. Extensive evaluations of these cultivars are being performed by Jerry Frecon, Emeritus Professor of the Rutgers Cooperative Extension System.

The table is set up according to average ripening dates for south-central Pennsylvania. The cultivars listed under the "Peaches" column are those that begin to ripen during the particular period. The next column reflects our opinion as to the best cultivars in that particular time frame. The third column contains suggestions for peach cultivars to try on an experimental basis. We do not know how well they will perform, but based on limited observation they seem worth trying on a small scale. The final column indicates all nectarines that ripen during that period.
