Hop plant named ‘YCR Accession No. 14’

Abstract

A new hop plant variety is disclosed. The new variety is used for its bittering and aromatic properties. The new variety is moderately tolerant to powdery mildew and Sphaerotheca. The new variety produces a medium size compact cone with good pickability and storageability. The cones mature early, and yield a crop of 2650 to 2880 pounds per acre (2970 to 3230 kg/ha).

Description

BACKGROUND AND SUMMARY OF INVENTION

This invention relates to a new and distinct variety of hop plant, and more particularly to a new hop plant variety of unknown parentage which was discovered among plants created as part of a controlled breeding program. The new variety has been stably reproduced over successive generations. Discovery of the new variety and initial reproduction by root cuttings was carried out in a research nursery in Prosser, Wash., U.S.A. Subsequent asexual reproduction took place in Granger, Wash., U.S.A.

DESCRIPTION OF THE VARIETY

The new hop plant variety is a cultivar of recent origin, used for its bittering and aromatic properties. The new variety is moderately tolerant to powdery mildew and Sphaerotheca. The new variety produces a medium size compact cone with good pickability (similar to Cascade, unpatented) and storageability (25% to 30% alpha loss after 6 months common storage). The cones mature medium early (about September 1 in Granger, Wash., and yield a crop of 2650 to 2880 pounds per acre (2970 to 3230 kg/ha).

The following is a detailed botanical description of the new and distinct variety of Humulus lupulus, based on observations of specimens grown in Granger, Wash. during the 1998 growing season. All colors are described according to The Royal Horticultural Society Colour Chart.
