SELECTION: Open-pollinated seedling of Golden Cluster (probably a California Cluster) from South Africa in the early 1940's

GENUS: Humulus

SPECIES: lupulus

CULTIVAR: Hybrid-2

PEDIGREE: Open-pollinated seedling of Golden Cluster

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

ORIGIN: South Africa, seedling selection


METHOD RECEIVED: Rhizomes, obtained from Dr. B. K. Bhat, Regional Research Laboratory, Sanat Nagar, Srinagar, India

AVAILABILITY: No restrictions, commercial variety

REFERENCES: USDA-ARS Annual Report of Hop Investigations for 1977, pp. 33-35

MATURITY: Medium to late

LEAF COLOR: Medium green

SEX: Female

DISEASES: Downy Mildew: moderately susceptible

Verticillium Wilt: unknown

Viruses: unknown


YIELD: 1400-2000 lbs/acre

SIDE ARM LENGTH: 12-36 inches

ALPHA ACIDS: 10.2% (5-year range 7.9-12.5%)

BETA ACIDS: 6.3% (5-year range 4.4-7.5%)


STORAGE STABILITY: Good to fair (retained 60% of original alpha acids after 6 months room temperature storage)

OIL: 0.91% (5-year range 0.62-1.15 ml/100 g)

MAJOR TRAITS: Similar to Yakima Cluster (USDA 65102) and Late Cluster (USDA 65104) but lower yield potential in the U.S. Storage stability not as good as Yakima Cluster, Late Cluster or Early Cluster.

OTHER INFORMATION: This hop, originally developed and released in South Africa, was discontinued in that country in 1964 because of decreasing yields. The selection was obtained from Cashmere, India in 1977, where it is still grown commercially. Like other Clusters, Hybrid-2 is susceptible to Downy Mildew but infected crowns generally do not die out in contrast to Cluster hops.
