Abstract: Genetic diversity of 110 pummelo germplasm and 12 its relatives were analyzed by SSR and AFLP. Approximately 99.1% of the 335 SSR were polymorphic, and 9.85 alleles per SSR loci were identified. Gene diversity values changed from 0.1939 to 0.9073, and 46 SSR polymorphic bands were scored. 72% of the 343 AFLP were polymorphic, and 82 polymorphic loci per AFLP were identified. Heterozygosity changed from 0.21863 to 0.28445, and 44 AFLP polymorphic bands were scored. The UPGMA result showed that 122 accessions of pummelo and their relatives were divided into eight groups, in which the pummelo genotypes mainly be composed of Shatian pummelo varieties group, Wendan pummelo varieties group and many hybrid pummelo groups. The classified result is beneficial for us to use various target varieties to widen the genetic background of pummelo.
