Abstract:Germplasm resources are an important basis for genetic breeding, and the study of genetic diversity is beneficial to the discovery and improvement of germplasm resources. In this study, 132 local germplasm of sweet potato were used as test materials, and 20 phenotypic traits were analyzed for genetic diversity using distribution frequency, coefficient of variation, and Shannon's diversity index; carotenoid contents in sweet potato tubers were measured by HPLC, and their genetic diversity was analyzed using the… Show more
