There is growing interest worldwide for Jatropha curcas because of the high oil content in the seeds, which can be used as base material for biodiesel production. This plant is native to Mexico (Mesoamerica) and can be found as toxic and non-toxic. However, there is little information on the genetic diversity of J. curcas. The purpose of this study was to analyze the genetic diversity of 64 accessions of J. curcas in the state of Veracruz, Mexico, and its relationship with the contents of phorbol esters. We used 12 microsatellites designed previously for this species. Loci were amplified using the polymerase chain reaction and alleles were separated on polyacrylamide gels. From all loci amplified, six were selected according to the clarity of the alleles and the polymorphisms generated. Heterozygous individuals were detected in only two of the six loci used. The accessions collected from northern Veracruz state were clustered together. Phorbol ester analysis confirmed the presence of toxic and non-toxic J. curcas. At the genetic level, none of the microsatellites employed were able to distinguish between toxic and non-toxic samples. Toxic plants were found in the central and southern parts of the state with phorbol ester contents ranging from 0.12 to 0.66 mg g-1, while non-toxic plants were distributed throughout the state. Given the importance of J. curcas as a biofuel, and the diversity of this plant species in the state of Veracruz, molecular techniques are helpful in locating and selecting individuals for breeding programs.
