Aims Our objectives was to investigate the genetic structure and diversity of ten natural populations of Jatropha curcas. Methods Seven loci encodings were detected by vertical polyacrylamide gel electrophoresis. Important findings The genetic diversity of J. curcas was high at the species level with a mean number of alleles per locus of 2.428 6, percentage of polymorphic loci of 97.14% and a mean expected heterozygosity of 0.396 4. A low level of genetic differentiation among populations (0.041 3) and a high estimate of gene flow (5.808 9) were detected together with a high level of genetic identity among populations (0.921 7–0.995 3). Unweighted pair-group mean arithmetic cluster analysis suggested that the genetic distances among populations were weakly correlated with their geographic distances. The results provided a good genetic base to select varieties.
