Hop plant named ‘HBC 692’

Abstract

A new hop plant named ‘HBC 692’ is disclosed. ‘HBC 692’ is used for its exceptional and unique aromatic qualities.

Description

Genus and species: Humulus lupulus.

Variety denomination: ‘HBC 692’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None

BACKGROUND OF THE INVENTION

‘HBC 692’ is a product of a controlled breeding program carried out by the inventors in the Yakima Valley of Washington State. ‘HBC 692’ was one of several seedlings resulting from an open pollination cross made in 2010 with female parent ‘HBC 438’ (U.S. Plant Pat. No. 29,577) and an unknown male parent. Seedling plants from this cross were planted in 2011 and screened for disease resistance and sex in a greenhouse and field nursery near Granger, Wash. A single plant of ‘HBC 692’ was selected in 2013. In 2014 ‘HBC 692’ was expanded by asexual tissue culture propagation via softwood cuttings, to 14 plants in an evaluation block near Toppenish, Wash. The ‘HBC 692’ plants have now been observed and evaluated for several years. Throughout several generations of asexual propagation, ‘HBC 692’ has been observed to retain its distinctive characteristics and remain true to type.

COMPARISON OF ‘HBC 692’ TO PARENT PLANT AND COMARISON CULTIVAR

Table 1. below, sets forth some of the distinguishing characteristics of ‘HBC 692’ as compared to its female parent ‘HBC 438’, and to the ‘Chinook’ cultivar as a closely comparable cultivar.
