MATURITY: Early to medium early

LEAF COLOR: Medium green

SEX: Female

DISEASES: Downy Mildew: moderately resistant

Verticillium Wilt: resistant

Viruses: unknown

VIGOR: Poor to good

YIELD: Low (1000 1200 lbs/acre)

SIDE ARM LENGTH: 6 20 inches

ALPHA ACIDS: 4.0% (7 year range: 3.3 6.0%)

BETA ACIDS: 1.5% (7 year range: 1.1-2.5%)

COHUMULONE: 27%

STORAGE STABILITY: Fair, retained 59% of original alpha acids after 6 months room temperature storage

OIL: 0.5 ml/100 g (7 year range: 0.15 0.98)

MAJOR TRAITS: Resistant to Verticillium Wilt, susceptible to Downy Mildew in England.

OTHER INFORMATION: Pleasant, European type aroma characteristics, high humulene content (35% of the oil); oil contains significant amounts of farnesene (in contrast to Density and Janus); this variety is not grown any more commercially because of low yields and low alpha acids content. The exceptionally low beta acids content results in a very high alpha:beta ratio, which may be useful from a breeding standpoint.
