Abstract: Abstract Jatropha curcas (L.) has gained popularity as a biodiesel plant to serve as an alternative fuel source and generate income to small landholders. The success of J. curcas as alternati ve fuel source and income generation depends on the identification of genetically divergent materials of the plant and developing superior planting stocks for farmers. This paper presents genetic diversity assessment of 40representative accessions drawn from 90 accessions collected from ten regions of G hana based on thei r seed yield performance. Random Amplified Pol y morĀ­ phic DNA (RAPD) anal ysis on the 40 accessi ons with ten primers revealed an average poly morphism of 24.99%. Genotype Genotype*Environmental bi plot anal ysis which incorporates divergence effects due to genotype (PCl) and interactions between genotype and field parameters (PC2) was 44.7%. Hence the RAPD information indicates narrow genetic diversity among the accessions used in the study and J. curcas germ plasm i n Ghana. It is therefore recommended tha t local germpl asm of J. curcas should be officiall y conserved and immediate efforts be made to widen the genetic base through research a nd introduction from other regions.
