Fredonia is an early black grape offered for northern planting in a 1937 Fruit Growers Service Co. catalog. The catalog calls it a new standout among early black grapes. It ripens about three weeks before Concord and was promoted for table use and market planting. [S1]
The source gives no breeder, parentage, release year, or place of origin for Fredonia. Its identity here comes from the catalog's grape section, where it appears with grapes promoted as able to grow and bear in northern regions. [S1]
The fruit has medium sized clusters and large, round berries held tightly on compact cylindrical bunches. The skin is thick and tough. The flesh is juicy, solid but tender, and rated very good in quality. [S1]
Fredonia's main value in this source is earliness. It ripens about three weeks earlier than Concord and is recommended as a table grape. The catalog expected it to become widely planted for market because of its very early season. [S1]
The vine is described as vigorous, productive, and heavy fruiting. The same catalog page says Fredonia, Worden, and Concord should be laid down and covered with earth through winter, while Beta needs no winter protection. This supports Fredonia as a grape promoted for northern planting, but not as fully hardy without protection in that catalog's region. [S1]
Fredonia was also sold in the catalog's advertising pages, where five plants were listed for $1.10. The source gives no taxonomic detail beyond its placement with grapes. It does not connect Fredonia to parent cultivars, siblings, or later breeding use. [S1]
