“…Species from the section Glossopetalum have been found to have significantly lower levels of palmitic and increased levels of arachidic than in T. cacao (Gilabert-Escrivá et al, 2002), suggesting the negative correlation between the two FAs. The negative correlation between C20:0 and C16:0 has also been identified in other plant species, such as in some peanut families and in wild safflower (Arslan, 2007; Wang et al, 2015).…”

The main ingredients of chocolate are usually cocoa powder, cocoa butter, and sugar. Both the powder and the butter are extracted from the beans of the cacao tree (Theobroma cacao L.). The cocoa butter represents the fat in the beans and possesses a unique fatty acid profile that results in chocolate’s characteristic texture and mouthfeel. Here, we used a linkage mapping population and phenotypic data of 3,292 samples from 420 progeny which led to the identification of 27 quantitative trait loci (QTLs) for fatty acid composition and six QTLs for fat content. Progeny showed extensive variation in fat levels and composition, with the level of palmitic acid negatively correlated to the sum of stearic acid, oleic acid, and linoleic acid. A major QTL explaining 24% of the relative level of palmitic acid was mapped to the distal end of chromosome 4, and those higher levels of palmitic acid were associated with the presence of a haplotype from the “TSH 1188” parent in the progeny. Within this region of chromosome 4 is the Thecc1EG017405 gene, an orthologue and isoform of the stearoyl-acyl carrier protein (ACP) desaturase (SAD) gene in plants, which is involved in fatty acid biosynthesis. Besides allelic differences, we also show that climate factors can change the fatty acid composition in the beans, including a significant positive correlation between higher temperatures and the higher level of palmitic acid. Moreover, we found a significant pollen donor effect from the variety “SIAL 70” which was associated with decreased palmitic acid levels.

“…He revealed differences in oil composition, ranging from 41 to 79 g/kg total oil for palmitic acid and 72 to 773 g/kg total oil for linoleic acid, are influenced by biogeography. Moreover, it has been shown that palmitic acid is positively correlated to the total seed oil content in safflower (Arslan, 2007). In contrast to safflower, in S. integrifolium , total oil content and palmitic acid are negatively correlated, which is in line with correlations of oil content and palmitic acid in sunflower (Petakov et al ., 1993).…”

“…For a domestication goal to generate an oilseed crop for human consumption similar to oilseed sunflower, a seed oil profile with low palmitic acid content should be achieved. Arslan (2007) showed that differences in seed oil content and seed oil composition among safflower cultivars as well as wild safflower relatives can be explained by their geographic origin. He revealed differences in oil composition, ranging from 41 to 79 g/kg total oil for palmitic acid and 72 to 773 g/kg total oil for linoleic acid, are influenced by biogeography.…”

Silphium spp. have garnered interest in Europe as a bioenergy crop and in North America as a perennial oilseed crop. However, very little has been done at this early stage of domestication to characterize wild collections for many key characteristics, including important oilseed traits. The objective of this work was to develop a basic understanding of how biogeography and associated population genetic forces have shaped seed phenotypes in plant collections across the native range of Silphium integrifolium Michx. (Asteraceae: Heliantheae), the primary domestication candidate for oilseed use. A collection of 53 accessions was grown in a common environment in Salina, KS, which is a location well within the native range of the species in central North America. Plants from each collection site were randomly mated by hand to produce seed representative of each accession, and the seeds subjected to seed dimensional trait, oil content and oil composition analyses. Kernel width varied along a latitudinal cline of collection site, while kernel length varied across a longitudinal cline. Palmitic and linoleic acids were inversely correlated with each other and varied along a longitudinal cline of the collection site. The results indicate that accessions collected from more southwesterly sites tended to have larger seed and those from more westerly sites had higher linoleic acid content and lower palmitic and myristic acids, which are all desirable phenotypes for an oilseed Silphium.

“…Discrepancies in seed oil content of safflower genotypes across countries have been observed by other researchers as well. For instance, safflower varieties of the USA namely Centennial and Montola-2000 recorded 42.3 and 38.3%, respectively at Sidney, Montana (Armah-Agyeman et al, 2002) while the same varieties recorded 29 and 35.2%, respectively in Turkey (Arslan, 2007). This is expected because the seed oil content in safflower is reported to be a quantitative trait, low heritable (Golkar et al ., 2011) and influenced by environments (Coşge et al, 2007; Ashrafi and Razmjoo 2010; Yeilaghi et al ., 2012).…”

Safflower is a traditional oilseed crop in the world. Its seed oil is a healthy edible oil containing high amount of unsaturated fatty acids. Genetically diverse exotic cultivars are valuable germplasm for introducing new diversity in safflower improvement programmes. In this study, we characterized safflower cultivars of India (30) and Mexico (23) comprising varieties, hybrids and advanced lines developed over 50 years for genetic distinctiveness using 38 simple sequence repeat (SSR) loci. Genetic diversity estimates across cultivar groups (total, India and Mexico) were as follows: mean number of alleles (3.2, 3.1, 2.6), expected heterozygosity (0.42, 0.37, 0.37) and polymorphism information content (0.36, 0.33, 0.32) respectively, which suggested narrow SSR allelic diversity within and between cultivar groups. However, distance-based cluster analysis (neighbour-joining tree) and model-based STRUCTURE analysis revealed that safflower cultivars of India and Mexico, with the exception of a few, form two genetically distinct groups. High level of genetic variation explained between the populations (40%) and Fst estimate (0.4) suggested that the cultivar groups were highly differentiated with limited gene flow supporting a strong genetic structuring. High oil (~38%) and high oleic (73–79%) contents of a subset of Mexican safflower varieties and advanced lines were confirmed in field trials in India. These exotic sources from Mexico are valuable for safflower breeding programmes in India to develop new cultivars with high oil yielding potential and high oleic acid content, which is the current market demand.
