Abstract: J. curcas is considered to be the most promising oilseed for biodiesel production. An investigation was carried out in five BC4F1 hybrid clones of Jatropha. A detailed study on variability was carried out for BC4F1generation to understand the variability available for growth and yield characters to formulate a selection index for the seed yield improvement program. Analysis of variance showed significant differences among all the characters. It indicates the presence of significant variability in the experimental materials. Studies on variability revealed that phenotypic and genotypic coefficients of variation exhibited wide range for all characters. Seed yield recorded a higher heritability value of 0.99. This trait also recorded a moderate genetic advance as percent of mean (34.85). Fruit yield, seed yield, number of primary branches and secondary branches recorded higher heritability with moderate genetic advance. The hybrid clone CJH 12 registered higher seed yield (334.70 g) and is found to be a superior clone and suggested that this clone can be deployed for commercial cultivation.
