Identification and characterization of new Vitis vinifera L. accessions from Romanian germplasm

This study focused on the comprehensive characterization of twenty-two grapevine accessions newly introduced and maintained ex-situ in the germplasm repository of the NRDIBH Stefanesti, in Romania. The results obtained with twelve SSR markers, 49 OIV traits and descriptions from old reference documents were put together to obtain a complete characterization. By comparison of the obtained molecular profiles with those collected in the Vitis International Variety Catalogue SSR database, two new synonyms, four misnomers and four new genotypes were found. One previously questionable variety was identified ('Negru tinctorial') and the correct name was associated to a genotype previously believed of Egyptian origin. The 22 accessions were morphologically described, the distinct characteristics for each genotype were highlighted and seven accessions were described for the first time.
