Genus and species: Humulus lupulus.
Variety denomination: ‘HBC 342’.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
None
BACKGROUND OF THE INVENTION
‘HBC 342’ is a product of a controlled breeding program carried out by the inventors in the Yakima Valley of Washington state. ‘HBC 342’ was one of several seedlings resulting from a cross made in 2001 of female parent ‘YCR 45’ (not patented) and male parent ‘97M2’ (not patented). A single plant of ‘HBC 342’ was selected in 2004, and was expanded to 70 plants, which were then planted in the area of Toppenish, Wash. The plants were observed and evaluated for several years, and in 2009 were expanded for further observation and evaluation in the Toppenish, Washington area. A 40 acre test plot of ‘HBC 342’ was established in 2009. Throughout several generations of asexual propagation by softwood cuttings at a greenhouse facility in Yakima, Wash., ‘HBC 342’ has been observed to retain its distinctive characteristics and remain true to type.

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 2010 growing season at Toppenish, Wash. Color descriptions refer to The Royal Horticultural Society Colour Chart. It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average.
