Abstract The aim of the study was to determine source variation in Jatropha curcas seeds collected from ten locations in Central India. A significant seed source variation was observed in seed morphology (colour, size and weight), seed germination (viability, germination percent, germination energy, germination value) and seedling growth parameters (survival percentage, seedling height, collar diameter, leave/plant, and seedling biomass). The seed source of Chhindwara (M.P.) was found as the best source in comparison to others. The phenotypic and genotypic variance, their coefficient of variability and broad sense heritability also showed a sizeable variability. This offers a breeder ample scope to undertake screening and selection of seed sources for the desired traits. Further, high percentage of heritability coupled with moderate intensity of genetic gain, was observed for seed germination traits, which signifies that germination is under strong genetic control and good amount of heritable additive genetic component can be exploited for improvement of this species.

• Direct shoot regeneration from leaf explants of Jatropha curcas in response to thidiazuron and high copper contents in the medium (2010, background): “Seeds are genetically heterozygous as Jatropha is cross pollinated, which results in a high degree of variation (Ginwal et al. 2005).”
• Genetic associations, variability and diversity in seed characters, growth, reproductive phenology and yield in Jatropha curcas (L.) accessions (2008, background): “…the germplasm was brought to Central Research Institute for Dryland Agriculture (CRIDA) and the seed/cuttings of germplasm of Jatropha collected during 2004–2005 and 2005–2006 were raised in the nursery for laying out trials in nursery as well as in field conditions to identify elite germplasm.”
• Plant-water relationships and growth strategies of Jatropha curcas L. seedlings under different levels of drought stress (2009, background): “Genetic differences 302 between accessions were related with significant differences in seed morphology (e.g. 303 Kaushik et al., 2007; Mukta and Murthy, 2008) and in seedling (Ginwal et al., 2005) and 304 plant height (Rao et al., 2008).”
