Methods and Results: We developed 16 polymorphic nSSRs from a genomic library tested in three populations of G. tessmannii and two populations of G. coleosperma. These nSSRs display three to 14 alleles per locus (mean 8.94) in G. tessmannii. Cross‐amplification tests in nine congeneric species demonstrated that the genus Guibourtia contains diploid and polyploid species. Flow cytometry results combined with nSSR profiles suggest that G. tessmannii is octoploid. Conclusions: nSSRs revealed that African Guibourtia species include both diploid and polyploid species. These markers will provide information on the mating system, patterns of gene flow, and genetic structure of African Guibourtia species. specialized AFRIQUE SUBSAHARIENNE 082 076 4 7 art. no 1600029 [4 ] 2016 2168-0450 https://www.documentation.ird.fr/hor/fdi:010073288 10.3732/apps.1600029 2168-0450 [F B010073288] https://www.documentation.ird.fr/hor/fdi:010073288 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers18-07/010073288.pdf IRD - Base Horizon / Pleins textes 2018-07-27 2018-08-09 fdi:010073288 fre
