Hop plant named ‘HBC 564’

Abstract

A new hop plant named ‘HBC 564’ is disclosed. The cones of ‘HBC 564’ mature in mid-September, and yield a crop of 2200 to 2600 pounds per acre. ‘HBC 564’ is used for its very unique aromatic quality, high alpha acid content and exceptional yield.

BACKGROUND OF THE INVENTION

‘HBC 564’ is a product of a controlled breeding program carried out by the inventors in the Yakima Valley of Washington state. ‘HBC 564’ was one of several seedlings resulting from a cross made in 2007 of female parent ‘Tillicum’ (patented) and male parent ‘HBC 20-9-10’ (not patented). A single plant of ‘HBC 564’ was discovered in 2010 and used in a brewing trial during the winter of 2010-2011. Based on the preliminary brewing trial, ‘HBC 564’ was expanded in the Toppenish, Wash. by means of asexual propagation by softwood cutting in 2011, and those plants were planted in a one acre block in the Toppenish, Wash. area to test large scale growing, brewing and solvent extraction beginning with the 2012 crop. Through several generations of asexual propagation by softwood cuttings at a greenhouse facility in Yakima, Wash. ‘HBC 564’ has been observed to retain its distinctive characteristics and remain true to type.

DETAILED BOTANICAL DESCRIPTION

The following description is based on observations made during the 2012 growing season at Toppenish, Wash.

‘HBC 564’ is distinguishable from its parent plants (‘Tilicum’ and ‘HBC 20-9-10’). ‘HBC 564’ is distinguishable from its male parent ‘HBC 20-9-10’ with flowers that develop into mature hop cones without producing pollen, while flowers of ‘HBC 564’ produce pollen without developing into mature hop cones.

Table 1. sets forth some of the distinguishing characteristics of ‘HBC 564’ as compared to its female parent ‘Tilicum’ and to ‘HBC 394’ (U.S. Plant Pat. No. 21,289):

		‘HBC	‘HBC
Characteristic	‘Tillicum’	564’	394’
Humulene Content of Oil (%)	14.0	28.0	24.0
Caryophylene Content of Oil (%)	7.4	14.0	8.0
Beta Acids Content of Cone (%)	9.5-11.5	7.5-9.5	4.5-5.5
Ploidy Condition	Diploid (but made	Triploid	Diploid
	tetraploid through
	application of
	colchicine)

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. Colour Chart, 4th ed., Copyright 2001, provided by The Royal Horticultural Society of Great Britain.
