Establishment of new strategies to quantify and increase the variability in the Brazilian Jatropha genotypes

•Jatropha curcas is one the most important plant to product biofuels.•Germoplasm bank is important to maintenance the variability of the Jatropha.•Jatropha curcas have high potential to increase yield production with breeding, and consequently increase oil content.•SNPs and DArTs are successful markers to identify variability between and within Jatropha families.
