USDA ACCESSION NO.: 21535

SELECTION: Selected from meristem tip culture/heat treated USDA 21525 at Prosser, WA in 1989

GENUS: Humulus

SPECIES: lupulus

CULTIVAR: Osvald Saazer clone 72Y, probably identical to the original Saazer (USDA 21077) except for freedom from viruses

PEDIGREE: Unknown, probably Czechoslovakian landrace grown in that country since the Middle Ages

PRIMARY SITE: USDA-ARS World Hop Cultivar Collection, OSU East Farm, Corvallis

ORIGIN: Prosser, Washington (via Czechoslovakia and Yugoslavia, hop variety collection at the Hop Research Institute Zalec, Slovenia)

DATE RECEIVED: Summer 1989

AVAILABILITY: No restrictions, commercial variety

REFERENCES: USDA Annual Report and Data Summary for Hop Investigations 1989, p. 34.

MATURITY: Early

LEAF COLOR: Green

Verticillium wilt: unknown, probably tolerant

Viruses: free of Prunus Necrotic Ringspot, Apple Mosaic, Hop Mosaic, Hop Latent Virus, and American Hop Latent Virus

VIGOR: Poor to good depending on location

YIELD: Good to poor (probably largely dependent on location and summer daylength)

SIDEARM LENGTH: 8 to 20 inches

ALPHA ACIDS: 3-5%

BETA ACIDS: 4-5%

COHUMULONE: 21-24%

STORAGE STABILITY: Fair

OIL: Unknown, probably below 1 ml/100 g

MAJOR TRAITS: Pleasant "noble" aroma suitable for production of super premium beers, mild bitterness, particularly suited for production of Pilsner-type beer.

OTHER INFORMATION:Very poor clustering, usually only two cones per side arm node. Identical to USDA 21525, except for freedom from viruses; commercial planting established at the Anheuser Busch BARI Hop Farms, Bonner's Ferry, Idaho in 1990 adjacent to the Canadian border where summer day length is 1-2 hours longer than in the Yakima Valley or in the Willamette Valley. Commercial yields at that location reportedly exceed 1000 lbs/acre. Not grown commercially anywhere else in the United States. Closely related (perhaps identical) to USDA 21077.
