SSR marker analysis demonstrated the presence of a high amount of genetic variation between the olive cultivars analyzed. A UPGMA dendrogram demonstrated that olive cultivars did not cluster on the basis of their geographic origin. Fatty acid components of olive oil in these cultivars were determined. The results also showed that there was a great amount of variation between the olive cultivars in terms of fatty acid composition. For example, oleic acid content ranged from 57.76 to 76.9% with standard deviation of 5.10%. Significant correlations between fatty acids of olive oil were observed. For instance, a very high negative correlation (-0.812) between oleic and linoleic acids was detected. A structured association analysis between the content of fatty acids in olive oil and SSR markers was performed. STRUCTURE analysis assigned olive cultivars to two gene pools (K = 2). Assignment of olive cultivars to these gene pools was not based on geographical origin. Association between fatty acid traits and SSR markers was evaluated using the general linear model of TASSEL. Significant associations were determined between five SSR markers and stearic, oleic, linoleic, and linolenic acids of olive oil. Very high associations (P < 0.001) between ssrOeUA-DCA14 and stearic acid and between GAPU71B and oleic acid indicated that these markers could be used for marker-assisted selection in olive.eninfo:eu-repo/semantics/openAccessBiochemistry & molecular biologyGenetics & heredityOlive (Olea europaea L.)Fatty acidsAssociation mappingStructure analysisSimple sequence repeatGenetic relationshipsOlea-europaea L.Microsatellite markersIdentificationCultivarsTraitsSoftwareRegionOlea europaeaAllelesCluster analysisFatty acidsGene frequencyGenetic variationGenotypeMicrosatellite repeatsOleaOlive oilPhenotypePolymorphism, geneticSpecies specificityArticle0003571927000752-s2.0-849259552232241225214125867371Biochemistry & molecular biologyGenetics & heredityOlea; Hedgerow; Genetic variabilityArachidic acidFatty acidGenomic DNALinoleic acidLinolenic acidLipidMyristic acidOleic acidOlive oilPalmitic acidPalmitoleic acidFatty acidMicrosatellite DNAOlive oilAgronomic traitArticleComputer programCorrelation coefficientCultivar identificationDNA markerFatty acid analysisGene assignmentGene clusterGene poolGenetic associationGenetic variabilityGeographic originLipid compositionNonhumanPhylogenetic treeSimple sequence repeatStructure analysisAlleleChemistryClassificationCluster analysisGene frequencyGenetic polymorphismGeneticsGenotypeMetabolismOlive treePhenotypeSpecies difference
