IDENTIFICATION OF SOME AUTOCHTHONOUS AND REGIONAL GRAPEVINE VARIETIES ACCORDING TO O.I.V. DESCRIPTORS FOR CERTAIN CHARACTERISTICS

Abstract

ABSTRACT Our studies included some autochthonous and regional grape varieties grown in the Republic of North Macedonia. The autochthonousvarieties were examined -White winter, Konchanka, Stanushina, Ohrid black and Ohrid white, and the regional varieties -Vranec, Prokupec, Smederevka, Zilavka and Zupljanka were examined.The tests were divided into three methodological units. The first method was applied to all varieties -data collection, history and comparison with other tests.The second method was performed on all varieties -ampelographic identification because we had samples from all varieties. In some of the varieties, the third method was performed, that is, genetic (DNA) identification was made in the period from 2010 to 2020 in different examination centers and at different times. The results are compared with the results of a study by Professor M. Aradhya of the USDA Research Center, Davis CA, USA. He has performed a wide range of genetic identification on a number of autochthonous varieties in Europe and Asia, including varieties in the Balkans.With the second method of examination -ampelographic identification according to O.I.V. descriptors we got the most realistic results. An ampelographic description of certain characteristics of the individual organs of the vine was performed and it was concluded that the varieties according to their anatomical and physiological characteristics belong to 2 groups: ecological-geographical group Black Sea varieties, subgroup Balcanica and ecological-geographical group Eastern varieties, subgroup Antasiatica.
