An affordable and convenient diagnostic marker to identify male and female hop plants.

Hop production utilizes exclusively female plants, whereas male plants only serve to generate novel variation within breeding programs through crossing. Currently, hop lacks a rapid and accurate diagnostic marker to determine whether plants are male or female. Without a diagnostic marker, breeding programs may take 1-2 years to determine the sex of new seedlings.

Identification of quantitative trait loci associated with R1-mediated resistance to powdery mildew and sex determination in hop (Humulus lupulus L.).

Two QTL were identified using linkage mapping approaches, one on hop linkage group 3 (qHl_Chr3.PMR1) associated with powdery mildew resistance and a second on linkage group 10 (cqHl_ChrX.SDR1) associated with sex determination.

Trait Mapping of Phenolic Acids in an Interspecific ( var. × ) Diploid Blueberry Population.

Blueberries ( sect. ) are a dietary source of phenolic acids, including chlorogenic acid (CGA) and related compounds such as acetylated caffeoylquinic acid (ACQA) and caffeoylarbutin (CA). These compounds are known to be potent antioxidants with potential health benefits.

First report of halo blight on hop (Humulus lupulus) caused by Diaporthe humulicola in Minnesota.

Halo blight, caused by Diaporthe humulicola, is an emerging issue in hop production in the Upper Midwestern and Eastern North America. Reports of halo blight thus far have included Connecticut, Michigan, New York, and Quebec (Allan-Perkins et al.; Hatlen et al.
