USDA ACCESSION No.: 21496
SELECTION: no information available
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

LEAF COLOR: dark green
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%
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
