Abstract: To realize the variations of the pepper phenotypic traits and their relationship, evaluation and correlation analysis of 14 phenotypic traits were conducted in 96 accessions from 5 cultivated species in Capsicum. The results showed the phenotypic traits had high genetic diversity among cultivated Capsicum species, and the coefficient of variation（VC）of 14 phenotypic traits ranged from 14.0%（the index of leaf shape）to 135.0%（fruit mean weight）. The fruit traits had complicated correlation with plant model traits, so it should be paid attention to select the phenotypic traits reasonablly according to the breeding goals in pepper genetic improving.
