POTENTIAL AND POSSIBILITIES OF REBO – NEW GRAPEVINE VARIETY (Vitis vinifera L.) IN GROWING CONDITIONS IN REPUBLIC OF NORTH MACEDONIA

Abstract

Rebo (Rigotti 107-3) is a vine variety that originates from Trentino, north Italy. It was selected by the researcher Rebo Rigotti by crossing the varieties Merlot x Terlodego at the agriculture and forest experimental station in S. Michele all’ Adige. According to the literature the idea of the breeder was to produce new variety that would be similar to Merlot but more resistant to cold climate conditions. Our idea to plant Rebo in Macedonia was to grow this variety on sites with higher altitude locations that are difficult for growing Merlot. The vineyard for this study is located in the north part of Macedonia on the mountain German near the town of Kriva Palanka, area typical for growing frost resistant varieties. In this research paper we analyzed the mechanical structure of the grape cluster and berries, the quantity of sugar and titratable acids in the grapes. In the wine we analyzed the quantity of total phenols, total anthocyanins, wine colour (CI;H), total flavan-3-ols and standard chemical analysis of the wine.
