LEAF COLOR: Medium to medium dark green
DISEASES: Downy Mildew: moderately resistant
Verticillium wilt: resistant
Viruses: slight infection with Prunus Necrotic
Ringspot, Apple Mosaic, and Hop Mosaic
VIGOR: Very good
YIELD: Very good to excellent (1800-2200 lbs/acre)
SIDEARM LENGTH: 20-40 inches
ALPHA ACIDS: 12.3% (10-year range 7.3 to 14.9%)
BETA ACIDS: 4.5% (10-year range 3.0 to 5.3%)
STORAGE STABILITY: Good to very good (retained 77% of original alpha acids after 6 months room temperature storage
OIL: O.90 ml/100 g; H/C ratio 0.07; contains very little humulene
MAJOR TRAITS: High yield potential, high alpha acids content, very late maturity.
OTHER INFORMATION: Difficult to pick, cones are hard to pull off, which slows down the mechanical picking process; no problems with cleaning; adapted to Oregon, Washington, and Idaho. In 1990 756 acres of Eroica produced a total of 1.3 million pounds with an average yield of 1728 lbs/acre. Eroica acreage has steadily declined in favor of Galena (USDA 21182) from a high of 1726 in 1985 to 641 acres in 1991. Total 1991 production was 1.23 million lbs, all in southern Idaho and Washington. In 1996, total production was only 380.600 lbs, all in Washington In 1997 Eroica had almost disappeared This selection is identical to USDA 21220 but carries Prunus Necrotic Ringspot and Apple Mosaic viruses.
