The genetic diversity of watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] in China, the world's largest producer of watermelon fruits, has not been examined. Two molecular markers, sequence-related amplified polymorphism (SRAP) and simple sequence repeat (SSR), were used to investigate the genetic variation and genetic relationship among 54 Chinese watermelon accessions, as well as 7 accessions from Africa, the United States, and Japan. SRAP assay generated 312 bands, of which 163 were polymorphic, while SSR assay detected 101 alleles with 87 polymorphic alleles and 114 genotypes. A comparative analysis of the diversity index, effective multiplex ratio, and marker index of …
