Ampelographic Characterization and Sanitary Status of Grapevine Cultivar ‘Prč bijeli’ (Vitis vinifera L.)

‘Prč bijeli’ is an old Croatian autochthonous grapevine cultivar (Vitis vinifera L.), which has not been ampelographically characterized in detail until now. Ampelographic description was performed following 52 morphological, 22 phyllometric and seven bunches dimension characteristics. ‘Prč bijeli’ showed acceptable yield and a must composition suitable for oenological purposes, with low acidity value and medium sugar content. The following synonyms were established: ‘Ćimavica’, ‘Parč’ and ‘Muškat’. The results of sanitary analysis (ELISA test on four viruses) on twenty-seven vines revealed that 92.6 % samples were GLRaV-3 positive, while ArMV was not detected. Only one vine was free of the tested viruses
