“…The high diversity found in Mexican accessions of J. curcas agrees with this investigation [5] [13] [44], which may be because Mexico and Central American is considered the center of origin of the Jatropha genus [45] [46] and has a high endemism [28]. Polymorphism indicates that inter-simple sequence repeats are abundant and highly dispersed through the genome [47].…”

“…Genotypes 70 and 80 were considered the most promising and with potential to be used in genetic plant breeding programs, as they presented higher seed weight, fruit weight and width, oil content and also lower plant height. In a study of physic nut seeds using genotypes from Suriname, Ethiopia, Nigeria, Brazil and China, Vaknim et al (2011) found that the oil content varied between 39 and 62%, Aguilera-Cauich et al (2015) verified an average of 50.52% oil content in American physic nut accessions, whereas in the present work values observed vary between 50.81 and 62.89%. Cluster analysis was performed using the Ward method, which generated the dendrogram shown in Figure 4.…”

“…In a study with phenotypic diversity of physic nut, Aguilera-Cauich et al (2015) found variability within the accessions and concluded in their study that are greater diversity among the American physic nut accessions evaluated in comparison with reports on diversity for India and Malaysia. Likewise, Trebbi et al (2015) verified an increased genetic variability and heterozygosity in physic nut accessions of Mexico and Guatemala.…”

Jatropha curcas is an interesting alternative for biodiesel production due to the high oil content in its seeds, its ability to grow in a wide range of climate and soil conditions as well as low cost of production. However, the species is considered to be in domestication and there are no defined cultivars. Therefore, it is extremely important to understand the genetic diversity of the species for selection and characterization of promising genotypes to initiate breeding programs. The objective of this study is to evaluate the phenotypic diversity of physic nut in order to select the most divergent and superior genotypes to compose future breeding programs, using multivariate analysis. Eleven agronomic characters were evaluated in 165 J. curcas genotypes from the in vivo germplasm bank, which were: Plant height, stem diameter, number of primary branches, fruit length, width, weight and shape, seed length, width and weight plus the oil content. The data were analyzed by principal component analysis (PCA), cluster analysis by Ward and k-means methods. The character fruit shape was removed from the multivariate analysis as the only one with qualitative character. The PCA resulted in 4 main components (PC), which explained 71.62% of total variance. The characters selected in PC1 were seed weight, fruit width, fruit length and fruit weight. There were 22 promising genotypes highlighted, with potential to be exploited in breeding programs. Cluster analysis by Ward and k-means methods generated 9 groups influenced by all analyzed characters, of which five groups of genotypes had advantageous characters. Regarding fruit shape, 13 genotypes had an ellipsoid lanceolate shape and the others had an ellipsoid spherical shape. Multivariate analyses allowed genotype characterization, indicating good strategies used for the selection in genetic breeding programs.

“…The range of variation of the present study was greater than that reported for germplasm from India and Cape Verde (1.49% − 10.53%) (Singh et al 2016a) and was similar to that of other American populations cultivated in Yucatan, Mexico (6.72% − 65.65%) (Aguilera-Cauich et al 2015). The variation between the American accessions indicates a high proportion of diversity compared to that of other regions, which is consistent with the fact that Mesoamerica has been proposed as the center of origin and diversity of the species (Heller 1996;Kamel et al 2018).…”

In this study, the variation of morphological and agronomic characters of 10 accessions of J. curcas selected from Yucatan, Mexico, and Honduras was analyzed. The characters associated with the proportions of the plants (height, number, and length of branches), the fruits (diameter and thickness), and the seeds (length, width, and volume), as well as those associated with the agronomic yield (number and yield of seeds plant− 1), explained the greatest variation between the accessions, 40 and 24%, respectively. The CAM32 and GAGI10 accessions had the lowest vegetative proportions and the highest agronomic yield, SUCILATEBEC and B5F59P19 had the lowest proportion and low yield, B3F119P1 had the highest proportion and high oil content, but low yield; while B5F83P1 had high values of vegetative proportions, and agronomic performance. The characters with the greatest variation among the accessions were ABM (59.93%), WV (56.91%), NS plant− 1 (57.18%), the SY plant− 1 (55.49%), and NL (54.37%). The similarity analysis grouped the accessions that had in common the geographical origin and the magnitudes of the characters associated with the agronomic performance and with the proportions of the plants, fruits, and seeds. The present study allowed the identification of J. curcas accessions with desirable agronomic and morphological traits, such as seed yield, oil content, and plant height, which can serve as progenitors in breeding programs for this species.
