Hybrid Franc


(Vinifera, Rupestris)



Hybrid Franc is the best-known cross between Rupestris and Vinifera.

It is one of the few varieties used in Europe as a resistant stock now

recommended for a direct producer. The vines are hardy, vigorous and

very productive. The fruit is fit only for wine or grape-juice, being

too acid to eat out of hand. The coloring matter in the fruit is very

intense and might be used in giving c
lor to grape products. The

variety is of French origin.



Vine vigorous, hardy, productive. Canes numerous, thick, light

brown with blue bloom; nodes enlarged; internodes short; tendrils

intermittent, long, bifid or trifid. Leaves small, thin; upper

surface light green, glossy, smooth; lower surface green, hairy

along ribs and large veins; lobes three to five with terminal one

acute; petiolar sinus narrow, sometimes closed and overlapping;

lateral sinus a notch. Flowers semi-fertile, open early; stamens

upright.



Fruit mid-season, does not keep well. Clusters medium in size,

short, cylindrical, single-shouldered, compact; pedicel long,

slender with few small warts; brush short, wine-colored. Berries

small, oblate, black, glossy with thick bloom, persistent, firm;
