History

'Ison' was releasedby Ison's Nursery in 1986. Plant patent #5822, Dec. 9, 1986. The listed pedigree is 'Sugar Gate' x 'Senoia'.


Comments

'Ison' has been used with moderate success by commercial growers in south Georgia. We only have a single vine of this cultivar, and therefore have only limited data. Because of its medium/large size and productivity, it has been used as a combination juice/fresh market cultivar. Flavor seems to be good as long as crop load matches the vine canopy, but some years the crop load is excessive. Clark (2001) noted that 'Ison' was extremely susceptible to cold damage. We only recommend trial plantings of 'Ison' in south Georgia.
