MATURITY: Medium late to late

LEAF COLOR: Green to moderately light green

SEX: Female, but occasional sterile male flowers develop

DISEASES: Downy Mildew: moderately resistant

Verticillium wilt: unknown, but probably resistant

Viruses: infected with Apple and Cherry strain of Prunus

Necrotic Ringspot virus, Hop Mosaic virus; shows conspicuous yellow flecking on lower leaves

VIGOR: Fair to good

YIELD: Poor to good

SIDEARM LENGTH: 12-24 inches




STORAGE STABILITY: Poor (retained about 50% of the original alpha acids after 6 months room temperature storage)

OIL: 1.3-1.6 ml/100 g; ratio humulene/caryophyllene 1.8-2.1

MAJOR TRAITS: Moderately high alpha acids content

OTHER INFORMATION: This hop together with its sister selections Ahil (USDA 21050) and Apolon (USDA 21051) and a related selection, Aurora (21053), entered the hop trade in the 1970's as Superstyrian hops. The implication was that they be similar to Styrian (Fuggle-type) hops but higher in alpha acids content. In reality they are Brewer's Gold seedlings, and their quality characteristics are different from the true Styrian (USDA 21049, Savinski Golding). This has caused considerable confusion in the world hop trade. Of the three sister selections Atlas had the greatest expansion in the late 1970's in Yugoslavia (over 400 acres). Acreage has since been reduced somewhat in favor of the old established Savinski (Styrian) Golding (USDA 21049).
