Genus and species: Humulus lupulus.
Variety denomination: ‘HBC 586’.
‘HBC 586’ is a product of a controlled breeding program carried out by the inventors in the Yakima Valley of Washington State. ‘HBC 586’ was one of several seedlings resulting from a controlled cross made in 2007 with female parent ‘YCR 21’ (unpatented) and male parent ‘01239-2’ (unpatented). Seedling plants from this cross were planted in 2008 and screened for disease resistance and sex in a greenhouse and field nursery near Toppenish, Wash. A single plant of ‘HBC 586’ was selected in 2010. In 2011 ‘HBC 586’ was expanded by asexual tissue culture propagation to 7 plants in an evaluation block near Toppenish, Wash. In 2017 ‘HBC 586’ was further expanded by asexual tissue culture propagation to a 1 acre test block near Toppenish, Wash. The ‘HBC 586’ plants have now been observed and evaluated for several years. Throughout several generations of asexual propagation, ‘HBC 586’ 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.
The following description is based on observations made during the 2015-2017 growing seasons at Toppenish, Wash. 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. Color code designations are by reference to the R.H.S.
