In this study, 220 individuals from seven native provenances and eleven introduced provenances of C. equisetifolia were analyzed to assess the genetic variation and structure using amplified fragment length polymorphism (AFLP) markers. A total of 465 bands were obtained by eight primer pairs, among which 153 were polymorphic. The mean NEI'S gene diversity H = 0.2113 calculated for 18 provenances and the total gene diversity HT = 0.4065 calculated for native provenances suggested abundant variation within provenances and species. High genetic divergence coefficient (G(ST), = 0.4737) and low gene flow (N-m = 0.5555) detected among native provenances suggesting high differentiation of C. equisetifolia. An AMOVA analysis for native provenances revealed a high proportion (46.07%) of the total in genetic variation distributed among provenances. The UPGMA clustering (r = 0.8028) and the Mantel test (r = 0.0716) for native provenances showed there was no correlation among genetic relationships and geographical distribution. The genetic information provided important implications for the future conservation and breeding programs of C. equisetifolia. specialized Casuarina equisetifolia AFLP markers genetic variation genetic structure native range introduced range 076 58 1-2 79-85 2008 0037-5349 https://www.documentation.ird.fr/hor/PAR00003854 0037-5349 https://www.documentation.ird.fr/hor/PAR00003854 IRD - Base Horizon / Pleins textes 2009-07-24 2017-08-23 PAR00003854 fre
