The species is primarily propagated through seeds, and thus the seed yield and oil content varies significantly. Propagation can also be carried out without losing the traits by stem cutting but the limitation is generation of large scale quality planting material. Thus, conventional propagation through seeds is not reliable and vegetative cuttings are inadequate to meet the demand of large scale quality planting material. Therefore, Jatropha improvement programme by modern methods of agrobiotechnology are of interest worldwide. Camara Machado has reported that regeneration in J. curcas is highly genotype dependent. Concerted efforts are being made to optimize genotype independent regeneration and genetic transformation protocol.en-USJatropha curcasThesis
