USDA ACCESSION No.: 21496

SELECTION: no information available

GENUS: Humulus

SPECIES: lupuls

CULTIVAR: Tettnanger A

PEDIGREE: no information available; the original Tettnanger (USDA 61021, and USDA 21015) probably arose from an old Landrace in southern Germany. Tettnanger A is a clonal selection made in the 1970s at the University of Hohenheim, Germany, (Dr. Schmuetz).

PRIMARY SITE: USDA-OSU Hop Research Farm, East Farm, Corvallis, OR.

ORIGIN: clonal selection

DATE RECEIVED: spring 1987

METHOD RECEIVED: rhizomes

AVAILBILITY: no restrictions, commercial variety

REFERENCES: Various USDA Annual Reports for Hop Research starting in 1987

MATURITY: early

LEAF COLOR: dark green

SEX: female

DISEASES: Downy mildew: tolerant

Verticillium wilt: tolerant

Viruses: free of all major hop viruses when received

VIGOR: fair to good

YIELD: fair to poor, poor clustering and cone set; averaged under 1,000 lbs/acre in Oregon commercial plots (Goschie Farms).

SIDE ARM LENGTH: 12 to 30 inches

ALPHA ACIDS: 4.4%

BETA ACIDS: 5.0%

COHUMULONE: 23%

STORAGE STABILITY: poor, lost over 60% of original alpha acids after 6 months room temperature storage

OIL: 0.85 ml/100 g. Humulene 16.6%; caryophyllene 5.1%;

Myrcene 47.2%; farnesene 13.6%. H/C ratio = 3.30

MAJOR TRAITS: pleasant continental-type aroma; low cohumulone content

OTHER INFORMATION: This hop belongs to the "Saazer Formenkreis--Saaz Group of Varieties" and is believed to be closely related to Saazer hop (USDA 21077). Tettnanger A and its sister selection Tettnanger B were thought to possess slightly higher alpha acids potential than the original Tettnanger. Based on Corvallis tests this may be questionable
