“…However, some accessions from Bangka (northern part) and Sumbawa (southern part) are similar to accessions from a particular location in Sulawesi, indicating that there was dispersion from Sulawesi to these two islands. Another study (Satyawan and Tasma, 2011) also suggested that most of the Indonesian J. curcas diversity probably reflects diversity in the ancestral population of the introduced germplasms than local differentiation.…”

Jatropha curcas L. is a potential bioenergy crop but has a lack of improved cultivars with high yields and oil content. Therefore, increasing our understanding of J. curcas germplasm is important for designing breeding strategies. This study was performed to investigate the genetic diversity and population structure of Indonesian J. curcas populations from six different islands. To construct a reference, we de novo assembled the scaffolds (N50 = 355.5 kb) using 182 Gb Illumina HiSeq sequencing data from Thai J. curcas variety Chai Nat. Genetic diversity analysis among 52 Indonesian J. curcas accessions was conducted based on yield traits and single nucleotide polymorphism (SNP) markers detected by mapping genotyping-by-sequencing reads from Indonesian population to Chai Nat scaffolds. Strong variation in yield traits was detected among accessions. Using J. integerrima as an outgroup, 13,916 SNPs were detected. Among J. curcas accessions, including accessions from other countries (Thailand, the Philippines and China), 856 SNPs were detected, but only 297 SNPs were detected among Indonesian J. curcas populations, representing low genetic diversity. Through phylogenetic and structural analysis, the populations were clustered into two major groups. Group one consists of populations from Bangka and Sulawesi in the northern part of Indonesia, which are located at a distance of 1572.59 km. Group two contains populations from islands in the southern part: Java, Lombok-Sumbawa, Flores and Timor. These results indicate that introduction of diverse J. curcas germplasms is necessary for the improvement of the genetic variation in the Indonesian collections.

“…The success of breeding depends on the availability of diverse germplasms [62]. However, some study showed narrow genetic diversity among the worldwide population [174][175][176][177][178][179]. It limits the success of conventional breeding.…”

Considering environmental issues and to reduce dependency on fossil fuel many countries have politicized to replenish fossil fuel demand from renewable sources. Citing the potential of Jatropha mostly without any scientific and technological backup, it is believed to be one of the most suitable biofuel candidates. Huge grants were released by many projects for huge plantation of Jatropha (millions of hectares). Unfortunately, there has been no significant progress, and Jatropha did not contribute much in the energy scenario. Unavailability of high-yielding cultivar, large-scale plantation without the evaluation of the planting materials, knowledge gap and basic research gap seem to be the main reasons for failure. Thus, the production of Jatropha as a biofuel has been confronted with various challenges such as production, oil extraction, conversion and also its use as a sustainable biofuel. In this chapter, we disclose the challenges and possible remedy for the contribution in the biofuel industry.
