The genetic diversity of mango (Mangifera indica L.) was determined among 188 mango accessions using 40 SSR markers. A total of 303 alleles were discovered, with a mean value of 7.58 and an average PIC of 0.583, showing that the SSR markers utilized in this investigation was quite informative. High Shannon’s index (1.304) and He (0.624) reflected the high genetic diversity of Chinese mango genetic resources. PCoA analysis and phenogram analysis divided the accessions broadly into groups representing their geographical origins and suggested a clear separation between M. indica and M. persiciformis. This expanded awareness of the genetic diversity of mango germplasm would aid breeders in choosing better parents, hence accelerating the delivery of improved cultivars to industry in order to satisfy consumer demand.
