The effects of gamma radiation on Cascade hop

Creator:: Getty, Brooke
Abstract:: This gamma irradiation study was conducted to establish an LD50 of the hop (Humulus lupulus L.) cultivar Cascade . The overall, long term goal is to generate replacement hop cultivars by inducing minor but significant DNA alterations with gamma radiation to improve agronomic quality without changing the brewing profile. The...

Potential Heterotic Groups in Hop as Determined by AFLP Analysis

Creator:: Townsend, M. Shaun and Henning, John A.
Abstract:: Hop (Humulus lupulus L.) is a perennial, dioecious species in which the female inflorescence (cones) are harvested and used in the beer-brewing process to impart bittering and/or flavoring to beer. Hop breeders have typically utilized clonal selection and hybridization to develop new cultivars. The use of genetically diverse parents for...

AFLP Discrimination of Native North American and Cultivated Hop

Creator:: Townsend, M. Shaun and Henning, John A.
Abstract:: Hop (Humulus lupulus L.) is cultivated for the female flowers, or “cones,” which traditionally have been used as a bittering and flavoring agent in beer. Hop breeding historically relied on relatively simple selection techniques within established breeding lines. Supplementing current breeding material with new genetic sources would enhance a hop...

Field-Based Estimates of Heritability and Genetic Correlations in Hop

Creator:: Henning, John A. and Townsend, M. Shaun
Abstract:: Hop (Humulus lupulus L. var. lupulus) is grown worldwide for the production of the dried female inflorescence (strobulus), or cones, used principally for the bittering and flavoring of beer. Information is scant on the inheritance of traits of economic importance in hop, and present knowledge is based on historical data...

AFLP Analysis of DNA from Dried Hop Cones

Creator:: Townsend, M. Shaun, Henning, John A., and Moore, Daniel L.
Abstract:: Hop (Humulus lupulus L.) cones are used extensively in beer brewing to enhance flavor and impart bittering. Verifying hops cultivar identity has traditionally been accomplished by morphological characteristics or a chemical analysis of lupulin glands but these traits may vary according to environmental influences. The objective of this research was...

Potential Heterotic Crosses in Hops as Estimated by AFLP-Based Genetic Diversity and Coefficient of Coancestry

Creator:: Henning, John A., Townsend, M. Shaun, and Kenny, Steven
Abstract:: Hop is a dioecious perennial with female plants grown commercially for brewing purposes. Parent selection in hop breeding on the basis of heterotic potential has not been reported in literature even though dominance has been reported in hops for several economically important traits. The objectives of this study were to...

Effect of Harvest Maturity on the Chemical Composition of Cascade and Willamette Hops

Creator:: Sharp, Daniel C., Townsend, M. Shaun, Qian, Yanping, and Shellhammer, Thomas H.
Abstract:: Considerable expertise is required to grow high-quality hops, and brewers and hop growers alike have a common goal of obtaining the highest quality hops possible. Change in the chemical composition of hops during plant maturation is a dynamic process requiring a comprehensive chemical and sensory analysis in order to maximize...

Registration of ‘Teamaker’ Hop

Creator:: Henning, John A., Haunold, Alfred, Townsend, M. Shaun, Gent, David H., and Parker, Thomas B.
Abstract:: ’Teamaker’ hop (Humulus lupulus L.) (Reg. No. CV-28, PI 558864) was developed by the USDA-ARS as a unique, nonbittering, high beta-acids hop and was released on 26 June 2006. The defining characteristics of Teamaker are its near-zero percent alpha acids levels—a distinctive condition in the Humulus species (Haunold et al.,...

QTL mapping of powdery mildew susceptibility in hop (Humulus lupulus L.)

Creator:: Henning, John A., Townsend, M. Shaun, Gent, David H., Bassil, Nahla, Matthews, Paul, Buck, Emily, and Beatson, Ron
Abstract:: Hop powdery mildew [Podosphaera macularis (Wallr.) U. Braun & S. Takam.] is best controlled via the production of resistant varieties. Recent evidence supports selection against plant susceptibility genes to fungal pathogens as a more durable resistance mechanism than selection for resistance genes. The objective of this study was to identify...
