S.  aMicrosatellite markers of genetic diversity and population structure of Carica papaya.h[electronic resource]  c2013  aWe assessed the genetic diversity of 96 papaya accessions by molecular characterisation using microsatellite markers. Fifteen polymorphic primers were selected. Accessions, which were classified as Common, Formosa and Solo according to fruit types, were evaluated for allele frequency, heterozygosity, polymorphism information content (PIC), inbreeding coefficient (f) and the genetic diversity structure. Fifteen primers amplified 68 alleles with an average of 4.53 per locus. PIC values ranged from 0.19 to 0.69. The observed heterozygosity (HO) was low for all selected microsatellites. High f estimates (0.58) and excess of homozygotes indicated inbreeding, mainly caused by the tendency to select hermaphrodite plants for succeeding generations. Analysis of molecular variance showed that most of the variation (98%) resides within subpopulation. The genetic analysis based on Bayesian statistics proved to be sensitive enough to detect relationships among the papaya accessions, grouping them into six clusters, irrespective of their classification types.  aMicrosatellite repeats  aPapayas  aCaracterização molecular  aMmamão1 aOLIVEIRA, E.
