Adaptability of Potential Genotypes of Jatropha Curcas L. as Bioenergy Source in Three Locations

The objective of this experiment was to identify new high yield varieties of jatropha, with oil content more than 35% by hybridization and selection. Hybridization in 2010 has resulted in nine potential genotypes and they are evaluated in different agro ecology. Evaluations were conducted in three locations i.e. Asembagus, Situbondo, East Java; Muktiharjo, Pati, Central Java; and North Lombok (NTB) from 2010 to 2013. The experimental design was a Randomized Complete Block Design with three replications; the plot size was 10 m × 8 m. The observations consisted of dry seed yield and seed oil content. The results elucidated that two genotypes had higher yielded than three control genotypes (IP-3A, IP-3P, IP-3 M) i.e. Lampung × SP-117 and Hs-49/NTT, the average productivity during three years are 1 018.64 and 988.13 kg ha–1 yr–1 The yield of genotype Lampung × SP-117 and Hs-49/NTT increased 29.13% and 25.26% compared with IP-3A. The seed oil content from two genotypes was 35.63% and 37.27% respectively, and both genotypes well adapted in all three locations.
