- Abstract : The Cu-Zn-superoxide dismutase (SOD) gene encodes an enzyme involved in the detoxification of superoxide radicals. The genotyping of this gene in 16 Tunisian olive varieties allowed the identification of an InDel-type SNP marker but also to validate the genotype-phenotype relationship between this marker and some quantitative (yield) and qualitative (olive oil quality) parameters. The phylogenetic analysis revealed a clustering into two groups independently of geographical origin. On the basis of bioinformatics analyses, highly significant associations were observed for varieties with the ID genotype producing more linoleic acid and for varieties with the II genotype having a high cholesterol level. This may suggest that varieties with genotype II (mainly Oueslati and Chemlali Tataouine) produce more oleic acid than linoleic acid than those with homozygous DD and heterozygous ID genotypes.
