Abstract
The new cultivar of grape originated from a hand-pollinated cross of ‘Dunstan-210’ (female parent, not patented) and ‘Black Monukka’ (male parent, not patented) made in 1970. The seedlings fruited in the summer of 1973 in a vineyard near Clarksville, Ark. and one was selected for its potential as a table grape for utilization in the southern United States. The original vine was tested as ‘Ark. 1400’. The new cultivar of grapevine is a white, seedless table grape which provides advancements in Pierce's Disease tolerance ( Xylella fastidiosa Wells et al.) for the southern region of the United States. This cultivar produces large, attractive fruit clusters with berries that have a neutral flavor and palatable, thin skin.
