VARIETY DENOMINATION

‘HBC 431’

BACKGROUND OF THE INVENTION

‘HBC 431’ is a product of a controlled breeding program carried out by the inventors in the Yakima Valley of Washington State. ‘HBC 431’ was one of several seedlings resulting from a open pollination cross made in 2004 with female parent YCR 223 (unpatented). A single plant of ‘HBC 431’ was selected in 2008, and in 2009 was expanded to 30 plants, which were planted in the area of Toppenish, Wash. The plants were observed and evaluated for several years, and in 2011 were expanded for further observation and evaluation in the Topennish, Wash. area. A 1 acre test plot of ‘HBC 431’ was established in 2011. Throughout several generations of asexual propagation, ‘HBC 431’ has been observed to retain its distinctive characteristics and remain true to type.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

FIG. 1 illustrates a mature ‘HBC 431’ hop plant grown on a trellis; and

The colors of these illustrations may vary with lighting conditions and, therefore, color characteristics of this new variety should be determined with reference to the observations described herein, rather than from these illustrations alone.

DETAILED BOTANICAL DESCRIPTION

The following description is based on observations made during the 2011-2014 growing seasons at Toppenish, Wash.
