| Summary: | Jatropha curcas L. is a vegetable oil plant growing
under diverse climates throughout the year. This
plant can adapt to very low rainfall areas and
marginal lands possessing low soil fertility, and
could produce high biomass as a potential cover
crop to reduce evaporation [1]. The J. curcas
biodiesel has numerous advantages, such as: more
environmental friendly due to its better emission,
higher combustion efficiency, biodegradable, and
renewable. Oil content in J. curcas is rather high
which can be used to replace diesel fuel to some
extent [2]. thus, the Jatropha biodiesel has the
potential to increase an independent fuel supply [3].
In an attempt to provide biodiesel fuel in
Indonesia, by the year 2025 the cultivation area
under J. curcas is intended to be increased to about
2.4×106 ha; the available land area for the purpose
in the country is a mostly dry and unproductive
otherwise [4]. The Directorate General of Plantation
has planned for J. curcas cultivation especially
in West Nusa Tenggara, East Nusa Tenggara,
Southeast Sulawesi, Gorontalo, Maluku, and Papua
areas [5]. However, a desirable variety of J. curcas
with high production potential and adaptability in
such areas is not available as yet. The success of the
breeding program to produce such a leading variety
relies predominantly on the available germplasm.
The potential of a good genotype source can be
exploited through introduction, exploration and
hybridization. In an effort for exploration of J.
curcas during 2005, the Centre for Research
and Plantation Development had collected 421
germplasm accessions from East Java, West Nusa
Tenggara, East Nusa Tenggara, and South Sulawesi
areas [6]. The variety improvement can be
attempted by utilizing a proper germplasm source
[8]. This research was conducted in the plantation
of J. curcas’s germplasm located in Asembagus –
Situbondo, East Java, Indonesia using seven local
accessions of J. curcas, i.e., HS49, SP16, SP38,
SP8, SM33, SP34, and SM35 [7]. |
