Abstract :
Istrian Peninsula, one of the fi ve districts within viticultural region of Coastal
Croatia, provides great geological-reliefal and climatic diversity and various production
conditions. Th is research studied the autochthonous varieties and their sanitary
status in old vineyards. Considering the age of vineyard, ten locations were chosen
where four autochthonous varieties ‘Malvasia istarska’, ‘Teran’, ‘Borgonja’, and
‘Pergola velika’ were identifi ed using ampelographic description according to OIV descriptors.
Morphological characteristics of chosen varieties were described using OIV
parameters and must was chemically analysed (pH value, sugar content, titratable
acidity). High intra cultivar variability was found for weight of a single bunch especially
for ‘Teran’. Th ere were also diff erences in sugar content of must particularly for
‘Pergola velika’. Must pH was low for all varieties with predominantly low acidity value.
Sanitary status of vines was determined by testing the plant samples for the presence
of three grapevine viruses (GLRaV-1, GLRaV-3 and GFLV) using DAS-ELISA.
Th e percentage of infection for GFLV was 55.6% while for GLRaV-1 and GLRaV-3 it
was 61.1%. Results showed that some morphological characteristics diff er from characteristics
described in literature. With purpose of preserving the biodiversity of autochthonous
varieties and for future researches, healthy propagation material will be
collected and planted in collection fi eld of autochthonous varieties at the Institute of
Agriculture and Tourism, Pore?.
