Origin, domestication, distribution and diversity of Jatropha curcas L.

Abstract

Jatropha has been identified as a potential plant source for biodiesel production. The study of its origin, domestication, distribution and extent of diversity would enable us in comprehending the plant species as a whole and to device strategies for its improvement. Hence, the origin of Jatropha and its climatic requirements for plant growth were examined. Also, its domestication and traits facilitating quick domestication have been highlighted. The pantropical distribution of the species has been detailed with special reference to Indian conditions where it has been reported all over the country. Finally studies on diversity involving molecular and phenotypic traits (field studies) and also efforts made for crop improvement involving intra and interspecific hybridization have been reviewed with emphasis on Indian Scenario. Breeding strategies for crop improvement have been suggested as a way forward.
