LEAF COLOR: Light green
DISEASES: Downy Mildew: resistant
Verticillium wilt: resistant
VIGOR: Very good
YIELD: Very good in Germany but variable in US test plots near Corvallis (10-year range 900-1700 lbs/acre with 1200 lbs/acre average)
SIDEARM LENGTH: 12-28 inches
ALPHA ACIDS: 8.5% (10-year range 6-10%)
BETA ACIDS: 4.4% (10-year range 3.8-5.4%)
STORAGE STABILITY: Good (retained 68% of original alpha acids after 6 months room temperature storage
OIL: 1.40 ml/100 g (10-year range 0.64-2.20)
MAJOR TRAITS: Highly resistant to hop downy mildew. Aroma and quality reported to be similar to Hallertauer mittelfrueh with higher alpha acids potential, but brewers disagree.
OTHER INFORMATION: Occasionally reported to be a triploid; chromosome number has not been rechecked. Hueller Bitterer, now simply called Hueller, is one of themajor new hop varieties grown in Germany in the mid- to late 1980's and early 1990's. Its acreage, however, has decreased in recent years in favor of Perle (USDA 21227), which has high alpha-acids potential. 1997 production was only 313.604 lbs on 235 acres. It is a triploid hop as confirmed by chromosome analysis (Feb. )994) : 2n = 3x = 30 chromosomes in roottip squashes.
