Biodiesel, an alternative diesel fuel, is produced from renewable biological sources such as
vegetable oils and animal fats (Sukarin et al, 1987; Kumar and Sharma 2008; Sujatha et al,
2008; Fangrui and Milford 1999; Sharama et al, 2011). Jatropha curcas is a drought-
resistant perennial shrub with an economic planting of 30-50 years. With the increasing
interest in biofuel, it is now considered as one of the promising sources of biofuel and has
proved to be a viable feedstock because of the 30% oil composition of its nut (Achten et al …

Abstract Jatropha populations from Malaysia, India, Indonesia, and the Philippines were
evaluated on inland soils at University Agriculture Park, Universiti Putra Malaysia with the
main objectives are to select superior plants with high seed and oil yields production for
commercial planting and to study inter-populations variation in morphological, seed and oil
yields characteristics. Analysis of variance shows that all traits had significant variation
among populations. Phenotypic correlations between seed yield per plant was positively …
