LEAF COLOR: Green to dark green
DISEASES: Downy Mildew: moderately resistant
Verticillium wilt: unknown, probably tolerant
Viruses: Infected with prunus necrotic ringspot virus and several other hop viruses
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%
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.
