MAJOR TRAITS: susceptible to hop mosaic; similar in quality to Golding-type hops (see USDA 21680, 21681, 21669 and others)

OTHER INFORMATION: This hop has a different growth type than other Golding hops, having sidearms pointing in a stiff upward direction. Arms also have a tendency to break easily at the branching point from the main stem. It is believed that this hop is actually a seedling of the original Petham Golding . (Opinion expressed by Dr. R.A. Neve during a visit to Corvallis in the early 1980s).
