Autumn Royal is a late-maturing black seedless table grape developed by David Ramming and Ron Tarailo of the USDA-ARS in Fresno, CA. The cultivar, formerly known and tested as USDA selection #A97-68, was released in 1996 and resulted from the cross of Autumn Black x C74-1. In addition to several USDA numbered selections, its parentage includes Blackrose, Calmeria, Flame Seedless and Ribier. The cultivar produces large, dark purple to black berries which ripen in late September to mid-October. The commercial appeal of Autumn Royal rests on its large berry size and late maturity, as well as the fact that relatively few inputs are required for the production of high quality fruit.
This vine is suiteable for zones 6, 7, 8, 9, 10
