Ruby-Roman is a new red table grape cultivar selectively bred from seedlings of Fujiminori, a tetraploid black table grape.Since it was first marketed in 2008, Ruby-Roman has attracted a great deal of attention due to some excellent characteristics such as bright ruby red berries which are extremely large in size such that the fresh weight exceeds 20 grams, nearly twice the weight of Kyohoberries, a popular and representative large-berry table grape in Japan.
