Abstract

The USDA hop breeding and genetics project at Oregon State University has accumulated more than 600 diverse hop genotypes from many parts of the world during the past 50 years. The genetic potential of this germ plasm has barely been tapped, particularly with regard to traits of interest to growers or brewers. By using selected lines for breeding, we were able to: combine high cone yield and high α-acids content, modify the α- and β-acids content and proportions, combine high α-acids content with superior storage stability, create an array of lines with cohumulone content varying from below 20% to above 65% independently of α-acids content, select lines differing in oil content by a factor of about four, and significantly modify the composition of essential oils.
