The<br />agronomic performance evaluation of Jatropha progeny which was derived from crossing of some Jatropha accessions has<br />been carried out for those goals. The study was conducted at Agro Techno Park, Indralaya South Sumatra. The crossing<br />combinations were Pidie x Medan, Curup x Lampung, Pidie x Lampung, Lampung x Pidie, Curup x Medan, Indralaya x<br />Pontianak, Medan x Palembang, Curup x Pidie, and Jogya x Komering. Oil production, nitrate reductase enzyme activity,<br />leaf chlorophyll content and relative plant growth rate were evaluated. The result showed that the relative plant growth rate<br />could be used as early detection parameter for yield potential. Progenies of Pontianak x Indralaya, Palembang x Indralaya<br />and Pidie x Lampung were selected as promising hybrids based on high productivity and heterosis effect.<br /&gt;Keywords: Jatropha curcas, heterosis, relative plant growth rate, nitrate reductase activity}, number={1}, journal={Jurnal Agronomi Indonesia (Indonesian Journal of Agronomy)}, author={Wijaya, Andi and Susantidiana, and HarunMuhamad Umar and Surahman, Memen}, year={2013}, month={Oct.} }
