“…Low genetic variation of local accessions in Africa and Asia should restrict their phenotypic performance, which would have resulted in the limitation in breeding programs. These results are consistent with previous reports ( Basha and Sujatha, 2007 ; Basha et al, 2009 ; Pamidimarri et al, 2010 ; Rosado et al, 2010 ; He et al, 2011 ; Montes et al, 2014 ; Montes Osorio et al, 2014 ; Ouattara et al, 2014 ; Yue et al, 2014 ; Guo et al, 2016 ; Montes and Melchinger, 2016 ; Siju et al, 2016 ). Exceptionally, Maghuly et al (2015) showed the most diverse population in Cape Verde by using 907 accessions from three continents.…”

Jatropha curcas L. (Jatropha), a shrub species of the family Euphorbiaceae, has been recognized as a promising biofuel plant for reducing greenhouse gas emissions. However, recent attempts at commercial cultivation in Africa and Asia have failed because of low productivity. It is important to elucidate genetic diversity and relationship in worldwide Jatropha genetic resources for breeding of better commercial cultivars. Here, genetic diversity was analyzed by using 246 accessions from Mesoamerica, Africa and Asia, based on 59 simple sequence repeat markers and eight retrotransposon-based insertion polymorphism markers. We found that central Chiapas of Mexico possesses the most diverse genetic resources, and the Chiapas Central Depression could be the center of origin. We identified three genetic groups in Mesoamerica, whose distribution revealed a distinct geographic cline. One of them consists mainly of accessions from central Chiapas. This suggests that it represents the original genetic group. We found two Veracruz accessions in another group, whose ancestors might be shipped from Port of Veracruz to the Old World, to be the source of all African and Asian Jatropha. Our results suggest the human selection that caused low productivity in Africa and Asia, and also breeding strategies to improve African and Asian Jatropha. Cultivars improved in the productivity will contribute to expand mass commercial cultivation of Jatropha in Africa and Asia to increase biofuel production, and finally will support in the battle against the climate change.

“…Meanwhile, the low diversity among these accessions may also be a result of the selection practice of farmers to obtain plants with higher yield, uniformity, oil content, and other traits of agronomic interest, which associated with vegetative propagation, cause narrowing of the genetic base. The low genetic differentiation among groups represented by genotypes from different regions of Brazil and the group of accessions from Mexico may indicate that Brazilian accessions have originated from the Mexican genetic background, as mentioned before and supporter by Pamidimarri and Muppala (2014); Pazeto et al (2015) and Guo et al (2016) .…”

“…Mexico is considered the center of origin of J. curcas, which has spread to other continents mainly by the Portuguese during the formation of their colonies (Pamidimarri and Muppala, 2014;Guo et al, 2016). As the center of origin of the species, the germplasm around the world is derived from Mexico, and a high similarity among them is expected.…”

ABSTRACT. Jatropha curcas L. is a highly promising oilseed for sustainable production of biofuels and bio-kerosene due to its high oil content and excellent quality. However, it is a perennial and incipiently domesticated species with none stable cultivar created until now despite genetic breeding programs in progress in several countries. Knowledge of the genetic structure and diversity of the species is a necessary step for breeding programs. The molecular marker can be used as a tool for speed up the process. This study was carried out to assess genetic diversity of a germplasm bank represented by J. curcas accessions from different provenance beside interspecific hybrid and backcrosses generated by IAC breeding programs using inter-simple sequence repeat markers. The molecular study revealed 271 bands of which 98.9% were polymorphic with an average of 22.7 polymorphic bands per primer. Genetic diversity of the germplasm evaluated was slightly higher than other germplasm around the world and ranged from 0.55 to 0.86 with an average of 0.59 (Jaccard index). Cluster analysis (UPGMA) revealed no clear grouping as to the geographical origin of accessions, consistent with genetic structure analysis using the Structure software. For diversity analysis between groups, accessions were divided into eight groups by origin. Nei's genetic distance between groups was 0.14. The results showed the importance of Mexican accessions, congeneric wild species, and interspecific hybrids for conservation and development of new genotypes in breeding programs.

“…The physic nut (Jatropha curcas L.) is a woody-shrub species belonging to the Euphorbiaceae family. The geographic center of origin of J. curcas remains controversial but is believed to be native to Central America or Mexico, where it occurs naturally in forests in coastal regions (Pecina-Quintero et al 2014;Guo et al 2016). Due to its performance superiority and environmental concerns, J. curcas is widely distributed in tropical and subtropical areas, especially in Central and South America, Africa, India and South East Asia (Schmook and Seralta-Peraza 1997).…”
