USDA ACCESSION NO.: 64100

SELECTION: Seedling selection from a cross made at Wye College, England, before 1920

GENUS: Humulus

SPECIES: lupulus

CULTIVAR: Bullion

PEDIGREE: Wild Manitoba BB1 x OR (open pollinated)

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

ORIGIN: Cross made by Professor E. S. Salmon at Wye College, England, before 1920. Seedling was raised in 1919 from open pollinated seed collected on the female BB1 in the hop nursery at Wye College, England. BB1 was obtained in 1916 as a cutting from a wild hop growing at Morden, Manitoba.

DATE RECEIVED: 1964

METHOD RECEIVED: Rhizomes, from Roger Kerr, Keizer, Oregon, who obtained it via S. S. Steiner Co. from England.

AVAILABILITY: No restrictions, commercial cultivar

MATURITY: Medium early

LEAF COLOR: Dark green

SEX: Female, occasional sterile male flowers in certain years.

DISEASES: Downy Mildew: moderately resistant

Verticillium wilt: resistant

Viruses: infected with all major hop viruses

VIGOR: Excellent

YIELD: High, 2000 to 2400 lbs/acre

SIDE ARM LENGTH: 20 40 inches

ALPHA ACIDS: 10.0% (10 year range: 6.7 to 12.9%)

BETA ACIDS: 5.4% (10 year range: 3.7 to 9.1%)

COHUMULONE: 39%

STORAGE STABILITY: Poor

OIL: 1.65 ml/100 g (10 year range: 1.14 to 2.70)

MAJOR TRAITS: Identical to USDA 21056

OTHER INFORMATION: Identical to USDA 21056 but slightly lower alpha acids content due to virus infection. This hop, a major U.S. hop variety since the mid-1940s, was discontinued from commercial U.S. production in 1985 after the advent of super-alpha hops with better storage stability and higher alpha acids content.
