Interpretive Summary:

Technical Abstract: Hop (Humulus lupulus) is a high-climbing, herbaceous perennial, dioecious vine, and has a long history of use as flavoring and stability agent in beer as well as nutraceutical medicine, bio-fuel fermentations and animal fodder. However, the modes of genetic inheritance and genetic diversity are poorly understood in hops. Application of a novel high-density molecular marker system: ~1.2M single nucleotide polymorphisms (SNPs) were profiled with genotyping-by-sequencing (GBS) among 4512 worldwide accessions, greatly advances our understanding of genetic diversity, genome-wide meiotic recombination structures, sex chromosomes, and candidate genes for sex determination in hops. Our more thoroughly understanding genetic parameters in hops are essential for speed and accuracy of hop crops breeding-- all improvements that will benefit hop growers in the not-too-distant future.
