'Tetra' Grape Released from the
Missouri State Fruit Experiment Station 

(G-2918)

('Herbert' X 'Worden')

This is a black grape of extreme size, equaling 'Columbian' and 'Golden Giant' in that respect. It is probably a tetraploid. The clusters are medium to large, loose, and ripen at the same time as 'Concord'. The large, round, black berry is sweet, juicy and with a much better flavor than most other very large grapes. The flowers have recurved stamens; vine growth is fair and production is good.  Introduced 1947.
