MATURITY: Late

LEAF COLOR: Light green

SEX: Female

DISEASES: Downy Mildew: moderately susceptible

Verticillium wilt: unknown, probably tolerant

Viruses: unknown

VIGOR: Good to very good

YIELD: Fair to good in U.S. trials, very good in Yugoslavia

SIDEARM LENGTH: 12-30 inches

ALPHA ACIDS: 4.8% (8-year range 3.1-6.9%)

BETA ACIDS: 6% (8-year range 4.0-7.4%)

COHUMULONE: 25%

STORAGE STABILITY: Good (67% of original alpha acids remaining after 6 months room temperature storage)

OIL: 0.60 ml/100 g (8-year range 0.39-1.0); H/C ratio 3.28; humulene 33%

MAJOR TRAITS: High yield potential in Yugoslavia but poorly adapted in many other parts of the world; good aroma properties, similar to established European "Noble Aroma" hops.

OTHER INFORMATION: Alpha acids content in the Backa Region of Yugoslavia has dropped dramatically in recent years to as low a 1%. The reasons are unknown but probably not due to viruses since spot tests by ELISA have revealed low virus titers. This hop is probably identical to USDA 21080.
