This study had been carried out at Forest College and Research Institute, Mettupalayam during 2009-2010 in Jatropha hybrid genetic resources to elicit information on performance, variability in seed and biometric traits, heritability, association analysis and biochemical properties. Twenty seven hybrid clones were used for the investigation and the experimental design followed was RBD. Significant variability was observed among the 27 hybrids with regard to the biometric traits viz., plant height, basal diameter, sturdiness quotient, number of primary and secondary branches and seed yield. The hybrid clones viz., HC 10, HC 21 and HC 22 recorded significantly higher seed yield than the rest of the clones. High and significant positive phenotypic and genotypic correlations were registered between number of primary and number of secondary branches on seed yield followed by basal diameter. Path analysis indicated that sturdiness quotient, basal diameter, number of primary branches and number of secondary branches expressed positive direct effect on seed yield.
