Problems solved by technology

In recent years, the procurement of hop raw materials by my country's beer production enterprises not only comes from real estate, but also imported hops also occupy a certain market share. However, some hop raw materials provided in the market are mixed to varying degrees, and beer companies have no convenience for hop raw materials. Effective means of identification, thus causing economic losses to beer companies

Abstract

The invention discloses a set of SNP sites suitable for identifying the variety and purity of hops. The set of SNP sites comprises five SNP sites for hops totally. Based on a whole genome sequencing result for 10 representative hop varieties at home and abroad, comparison and screening are carried out on the SNP sites of the whole genome, at present, the identification for the variety and purity of hops of 5 SNP sites with relatively good polymorphism is verified, the 5 SNP sites can identify the variety of the hops, meanwhile, a genotype result is stable, and after the follow-up verification work for the authenticity of the SNP sites is completed, an SNP site fingerprint database of the hops is complemented to be complete. With the SNP sites and the identification method provided by the invention, an identification system for the variety and the purity of hops, which realizes low cost, high efficiency and standardization is provided for the beer production industry.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a set of SNP sites suitable for identifying hop varieties and purity and applications thereof. Background technique [0002] Hops (Humulus lupulus), also known as hops, fragrant hops, hops and wild hops. In my country, it is mainly distributed in Xinjiang, Northeast China, North China and Shandong, Gansu and Shaanxi provinces. Hops is a crop with valuable economic value and medicinal value. Hops contain resins, volatile oils, flavonoids, tannins, choline, crude fibers, amino acids and other chemical components, which have antibacterial, antitumor, antioxidant, sedative and other activities. The resin contained in it gives the beer a unique aroma and refreshing bitter taste; tannin can not only eliminate the lactic acid bacteria produced during the fermentation process, but also solidify and separate the excess protein in the wine to clarify the wine. Therefore, hops ar...
