Abstract

Aim: The objective of the present study is to investigate the molecularcharacteristics of Sardinian grapevine cultivars to evaluate cases ofsynonyms and false attributions to protect local agro-biodiversity.Methods and results: The SSR analysis (13 loci) has been used to definethe DNA fingerprint and the relationships with Sardinian grapevine cultivars.Results highlighted a high genetic variability among the accessions, withthe Dice coefficients performing from 0 to 0.8. Despite the genetic richness,thirteen groups of redundant genotypes were detected. Molecular analysisrefers of cultivars harbouring the same SSR profile but different berrycolours such as cultivars Licronaxu Bianco and Nero and MoscatelloBianco and Nero. It could by hypothesized that Licronaxu and Moscatellocould derive from a specific retrotransposon-induced mutation event ingenes regulating anthocyanin biosynthesis.Conclusion: Sardinian germplasm has a real problem of cultivaridentification probably due to different factors such as the absence of anexhaustive ampelography, problems in the language to name varieties andthe existence of cultivars sensitive to biotic and abiotic stresses producingevident morphological modifications leading to mistakes in recognisingand identifying properly the affected plants. However, our molecular resultssuggest that high grape-biodiversity is still preserved in this region.Significance and impact of study: Results of this work clarified therelationships among grapevine cultivars and provided a solid basis toimprove a regional grapevine collection.
