Abstract

A molecular marker combination linked to quantitative traits of tea plant caffeine content, including a SNP site 1, a SNP site 2, a SNP site 3, a SNP site 4, a SNP site 5 and a SNP site 6, which are located in tea genomes Scaffold4239:309117, Scaffold115:803980, Scaffold720:596655, Scaffold3614:66549, Scaffold349:3413816 and Scaffold920:281727, respectively, and genotypes thereof are extremely significantly correlated with the caffeine content is provided. A detection method for detecting each site, and one or more molecular marker site is used to evaluate the tea plant caffeine content.
