Abstracts
During a number of years, the world trends are preserving and creating a sustainable development of viticulture, based upon origin and typical varieties in certain wine growing areas. Scientific research conducted since 2003 within the project Genetic and economical resources
of Vitis sp., started in 2003 and continued in 2006 with the project Valorisation of wine grapes (Vitis sp.) and gene bank (2006–2012), autochthonous sorts of wine grapes were thoroughly examined
throughout Istria, with the aim of economical and genetic valorisation.
Following 12 years of field research, with the commitment of a large group of scientists and technical personnel from the Institute, around a hundred vineyards were examined throughout Istria. In order to find and identify the old Istria varieties, examined vineyards were 50 to 100 years of age, grafted in situ, containing different genetic and economical characteristics. Based upon field research on hundreds of wine stocks and gathered data from eighty vineyards, numerous biotypes that could not be set in the context of the already known old varieties, with interesting ampelographic characteristics, were identified.
All biotypes were ampelographically identified and described. Morphological characteristics were described with OIV indicators. Chemical analysis of must was conducted (pH, content of sugar, acidity), as well as the DAS-ELISA test for sanitary condition.
The majority of selected biotypes collected during 2005–2012 were grafted on the new trial plots Gene Collection of autochthonous wine grape varieties on the land belonging to the Institute of Agriculture and Tourism in Poreč. On the plots of 7,182 m2, we have successfully
planted 3,591 wine stocks. This plantation is today a base for creating new clones of autochthonous sorts in Istria.
The Gene Collection is a base for long-term and sustainable development in Istria, as there exist no matricular plantations of wine grapes according to current laws that could be a source of quality seedling material with genetic origin from Istria.
