USDA ACCESSION NO.: 65101
SELECTION: Open pollinated seedling of Late Cluster, selected in 1959 from seed collected in 1958, following screening for downy mildew resistance in the seedling stage.
PEDIGREE: Late Cluster x Open Pollinated (OP)
PRIMARY SITE: USDA World Hop Cultivar Collection, OSU East Farm
ORIGIN: Selected by R. R. Romanko at Parma, Idaho, among open pollinated seedlings of Late Cluster, following downy mildew screening.
DATE RECEIVED: 1965
METHOD RECEIVED: Rhizomes
AVAILABILITY: No restrictions, commercial variety

MATURITY: Very late (mid-to late September)
LEAF COLOR: Dark green
DISEASES: Downy Mildew: moderately resistant
Verticillium wilt: resistant
Viruses: carries prunus necrotic ringspot virus and some other hop viruses without appreciable effect on yields.
YIELD: 2000 2600 1bs/acre
SIDE ARM LENGTH: 24 to 40 inches
ALPHA ACIDS: 6.2% (5 year range: 5.7 to 6.7%) Alpha acids in excess of 8% have been recorded frequently in the Yakima Valley
BETA ACIDS: 3.2% (5 year range: 2.8 to 3.6%)
STORAGE STABILITY: Very good, similar to Clusters
OIL: 0.72 ml/100 9 (5 year range: 0.47 to 0.98)
MAJOR TRAITS: Moderately high alpha acids content; was preferred hop extractors over other Cluster type hops prior to the advent of super alpha hops. Excellent yield potential. Somewhat better downy mildew resistance than Clusters.
OTHER INFORMATION: Relatively sparse regrowth in early spring; few rhizomes on mature crowns. After its release in 1965 Talisman expanded to 1437 acres (4.6% of U.S. production) in 1973. Since then, acreage has gradually declined, and in 1986 only 222 acres of Talisman were grown commercially. Talisman was used as replacement for Clusters in blends, although some brewers complained about harsh aftertaste of Talisman flavored beers. No Talisman was grown commercially in the United States in 1997.
