中国啤酒花种质资源与育种研究OA

Hop(Humulus lupulus L.)is the core raw material determining beer's flavor,foam,and stability,revered as the"soul of beer."Although China is a major producer and consumer of hops,it has long faced challenges such as a limited range of main cultivars,a narrow genetic background,and a scarcity of characteristic aroma varieties.This paper systematically reviews the advances in the collection,conservation,and genetic diversity evaluation of hop germplasm resources in China,particularly the wild resources from Xinjiang and other regions,revealing their unique breeding potential.Concurrently,the article outlines the breeding journey from introduction and domestication to independent innovation,summarizing breeding strategies and achievements that integrate conventional hybridization with modern biotechnology.Furthermore,it provides an in-depth analysis of key issues within the industry concerning varietal structure,scientific research investment,and industrial chain coordination.Finally,strategies are proposed to construct a modern hop variety system with independent intellectual property rights and Chinese regional characteristics by strengthening germplasm innovation,promoting precision breeding technologies,selecting characteristic varieties,and establishing an integrated industry-academia-research system.These efforts aim to facilitate China's transition from a large hop-producing country to a powerful one in the hop industry.
