Growth performance, variability in yield traits and oil content of selected accessions of Jatropha curcas L. growing in a large scale plantation site

Jatropha curcas L. (JCL) is gaining global popularity as a potential feed stock of biodiesel and a candidate species for waste land reclamation. Although the oil yield of this species is better than any other non-edible oil yielding plants, the lack of agronomic practices defame this species for further exploitation. Furthermore, there is paucity of data on the growth performances and yield of JCL plantations. In this context, a systematic study on passport data and yield performance of JCL germplasms (including their indigenous collection number (IC No.), morphological characterization of seeds and seed oil content) growing in a large scale plantation site at Solar Energy Center, Gurgaon, India were carried out during 2007–2008. Ten elite accessions of JCL were screened from this site based on their growth performance and biomass characterization and were deposited at National Bureau of Plant Genetic Resources, New Delhi for registration. The oil content of the 10 registered accessions was ranged from 17% to 34%. Cluster analysis was performed to find out promising germplasms. Cluster analysis formed two prominent groups, each one with two sub-clusters. The promising accessions can be further explored for crop improvement programs. Furthermore, multi-locational trials are essential for optimizing the agropractices for maximum yield for a sustainable biodiesel production.

► Jatropha curcas L. (JCL) is getting global popularity as an oil plant of multiple benefits.
► Growth and yield performance of selected JCL accessions growing in large scale plantation sites was demonstrated here.
► The oil content of the ten JCL accessions was varied from 17 to 34%.
► The promising JCL accessions can be explored further for the detailed genetic and molecular profiling for crop improvement.
