Color: White/green Fruit Maturity: Mid-late

Clusters Small, cylindrical shouldered Wood Maturity: Mid-late

Berry: 10-12 mm, ovoid Cold Hardiness: Moderate - 3

Cluster Compactness: Well filled to compact Killing Temperature: -9.4°F

Disease & Disorders: Botrytis, crown gall Relative Vigor: Moderately

Location Year Wt. (lb) (%) (grams) (Tons/Acre) Date (%)

Geneva 1985 0.5 -- 34 1.3 34609 18.5

1986 0.9 93 79 2 34621 --

1987 2.3 82 81 2.7 34587 16.5

Mean 1.2 88 65 2 34605 17.5

Summary: Vines have had some crown gall and botrytis bunch rot is frequent. Weak growth and appearance on C. 3309 rootstock suggests questionable virus status. Full bodied and fruity, pleasant wines are generally produced. In Europe, this has been one

Recommendations: There are suggestions that the variety is slow to become established, but our experience does not support a recommendation for any except experimental planting.
