Abstract (EN): The grapevine (Vitis vinifera subsp. vinifera) is one of the most important agricultural crops worldwide. A long interest in the historical origins of ancient and cultivated current grapevines, as well as the need to establish phylogenetic relationships and parentage, solve homonymies and synonymies, fingerprint cultivars and clones, and assess the authenticity of plants and wines has encouraged the development of genetic identification methods. STR analysis is currently the most commonly used method for these purposes. A large dataset of grapevines genotypes for many cultivars worldwide has been produced in the last decade using a common set of recommended dinucleotide nuclear STRs. This type of marker has been replaced by long core-repeat loci in standardized state-of-the-art human forensic genotyping. The first steps toward harmonized grapevine genotyping have already been taken to bring the genetic identification methods closer to human forensic STR standards by previous authors. In this context, we bring forward a set of basic suggestions that reinforce the need to (i) guarantee trueness-to-type of the sample; (ii) use the long core-repeat markers; (iii) verify the specificity and amplification consistency of PCR primers; (iv) sequence frequent alleles and use these standardized allele ladders; (v) consider mutation rates when evaluating results of STR-based parentage and pedigree analysis; (vi) genotype large and representative samples in order to obtain allele frequency databases; (vii) standardize genotype data by establishing allele nomenclature based on repeat number to facilitate information exchange and data compilation.
