Abstract
Development of Jatropha as a source of biodiesel to dry land, a wide area in Indonesia, has been an urgent situation due to limitation of fossil fuel. The use of superior varieties is an imperative effort, however, their number is still limited. Some local genotypes which were originally from West Nusa Tenggara, namely IP-3A, IP- 1A, West Lombok Genotype, Bima Genotype, IP-2NTB and others, have specific superior character such as drought stress tolerant and high yield. The result of completely dialell hybridization among them showed that some hybrids namely 2NTBx3A, LBx2NTB, 3Ax2NTB, 3Ax1A-a, LBx3A, 3Ax1A-b, and BMx3A had superior characters in term of seedling growth, vegetative growth and yield in the first year of production cycle, compared to the other hybrids and their parentals. The growth and the general performance were getting better in the F2 generation in the second year of production cycle. The hybrid of 2NTBx3A and 3Ax1A showed the highest yield potency (98.7 g and 101.1 g, respectively), compared with the other hybrid populations.
