Abstract
Hops and pears are important agricultural commodities in the United States, particularly in Washington State. Hop, Humulus lupulus, is a cone-bearing plant that produces essential oils and organic acids that contribute to the flavor, aroma, and bitterness of beer. Washington hop production exceeded $200 million in 2013, accounting for 81% of the U.S. production value. Pears are an important tree fruit crop and are an excellent source of fiber and vitamin C, 18 and 10% respectively. In 2012, Washington State was responsible for 47% (over $205 million) of the United States pear production value, followed by Oregon State and California with 30% and 20%, respectively. To maintain and improve the viability of these industries in Washington State, hop and pear breeding programs must continue to create disease resistant and desirable cultivars using diverse parental material. Evaluating genetic relationships among new parental material for these breeding programs is critical for helping breeders make crosses between diverse v individuals. This thesis presents information on genetic diversity in breeding parents for hops and advanced rootstock selections for pear, and helps to resolve genetic relatedness between genotypes. Genetic relationships among hop parental genotypes used in the
