Interspecific Jatropha hybrid species is one of the most important techniques to improve the yield and favorable characteristics of Jatropha curcas. Interspecific hybridization among Jatropha species which transfers useful traits such as high oil content, maximum number of seeds, more femaleness, and hard stem could create a hybrid varieties of Jatropha which have combined favorable characteristics. One kind of hybrid variety which has potential to increase seed oil production is hybrid variety between Jatropha curcas and Jatropha integerrima.
