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...

Full Text:: Estimates of Heritability and Genetic Correlations in Hop John A. Henning* and M. Shaun Townsend ABSTRACT

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...

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...

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...

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...

Abstract:: NM-9D11A-AN3 alfalfa (Medicago sativa L.) germplasm (Reg. no. GP-337, NSL 386506) was developed by the New Mexico Agricultural Experiment Station and released 5 Oct. 1998. NM-9D11A-AN3 has demonstrated high yield potential under deficit irrigated field conditions in southern New Mexico. It is highly resistant to anthracnose (caused by Colletotrichum trifolii...

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.,...

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...

Abstract:: Nitrogen-fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation may affect cyanolichen growth rates, we fertilized a tripartite cyanobacterial lichen (Lobaria pulmonaria) and a green algal...

Abstract:: The trace element molybdenum (Mo) is essential to a suite of nitrogen (N) cycling processes in ecosystems, but there is limited information on its distribution within soils and relationship to plant and bedrock pools. We examined soil, bedrock, and plant Mo variation across 24 forests spanning wide soil pH gradients...
