Pollen fertility percentage is conducted for 10 Jatropha species and an interspecific backcrossing hybrid between Jatrophacurcas x Jatropha integerrima (BC3F1). Totally nine species namely Jatropha villosa var. villosa , Jatropha villosa var.villosa , Jatropha multifida, Jatropha podagrica, Jatropha maheswarii, Jatropha glandulifera, Jatropha gossypifolia,Jatropha integerrima and Jatropha curcas had more than 84 per cent of pollen fertility. BC3F1 hybrid recorded the highestpollen fertility percentage of 97.54, while Jatropha tanjorensis had 0.16 per cent of pollen fertility which amounts to nearsterility.
