摘要

Grapevine is an important commercial crop widely grown in the world. However, grapevine cultivation has long been seriously threatened by grapevine downy mildew caused by Plasmopara viticola. Screening the resistance resources and identifying the resistance germplasm is the key to improve the resistance of cultivars to P. viticola. East Asia is one of the three origin regions of wild grapevine (North America, Eurasia and East Asia), and many varieties have strong disease resistance. In present study, we selected nine wild East Asian grape vines and selected three of them with the highest P. viticola resistance to construct genetic populations. Genotyping by Targeted Sequencing (GBTS) is a high-throughput and cost-effective technology for sequencing specific genome regions, and its application in genetic population analysis and disease resistance related markers identification has revealed that may be abundant P. viticola-resistant germplasm in East Asian grapes. Our sequencing data and disease resistance grade data provided a valuable reference for mining downy mildew resistant germplasm of East Asian grape and breeding resistant varieties.
