MATURITY: Early

LEAF COLOR: Green to dark green

SEX: Female

DISEASES: Downy Mildew: moderately resistant

Verticillium wilt: unknown, probably tolerant

Viruses: Infected with prunus necrotic ringspot virus and several other hop viruses

VIGOR: Poor

YIELD: Low (200-400 lbs/acre near Corvallis, probably higher in Poland)

SIDEARM LENGTH: 6-20 inches

ALPHA ACIDS: 3-5%

BETA ACIDS: 2.5-5%

COHUMULONE: 23%

STORAGE STABILITY: Fair (retained 58% of original alpha acids after 6 months room temperature storage)

OIL: 0.5 ml/100 g, H/C = 3.33, humulene 27% of the oil

MAJOR TRAITS: Fine European type aroma.

OTHER INFORMATION: Green stem (in contrast to Lubelski, USDA 21113); Nadwislanska, an old variety, is no longer grown commercially in Poland. A virusfree Nadwislanska was developed in the 1980's at Prosser, Washington through heat treatment and meristem tip culture (USDA 21524). Its yield potential, however, has not improved by removing the viruses.
