Ampelographic characteristics of new wine varieties created at the experimental station 'Radmilovac'

Faculty of Agriculture, Department of Viticulture, Belgrade-Zemun (1,2)


Six new varieties: Godominka, Jagodinka, Kladovska White, Tenturier of Kraina, Srpski Rubin and Tenturier of Župa were created at the Faculty of Agriculture in Zemun. Ampelographic researches according to the method OIV-IBPGR-UPOV included the following characteristics: young shoot (8), tendril (1), young leaf (2), mature leaf (14), flower type (1), bunch (3), berry (6), seed (1), must quality (2). These varieties were compared with parental varieties: Prokupac, Dymiat, Pinot Noir, Gamay Noir, Gamay Tenturier and Alicante Henry Bouschet. The data were processed by applying the hierarchy method of grouping and discrimination analysis. It is noticeable in the dendogram (Fig. 1) that the two autochtonous varieties Prokupac and Dymiat belonging to the ecological and geographic group convarieties Pontica, subconvarietas Balcanica were separated against the newly created and introduced varieties used in hybridization. The similarities between these two varieties were caused by the similarities in the tip of young shoot and mature leaf - i.e. size of blade (characteristic 065), shape of blade (067), number of lobes (068), colour of the upper surface of blade (069), shape of base petiole sinus (080), prostrate hair between veins (084), erect hairs between veins (085) since they possess the characteristics of the group they belong to - convarietas Pontica. Another subgroup of the branching tree includes the varieties Jagodinka, Srpski Rubin, Gamay Noir, Kladovska White and Pinot Noir. Godominka is at the very end of this subgroup and its characteristics of the bush and berry were crucial in classifying this variety with varieties created in combination of Prokupac, Gamay Noir and Pinot Noir. The varieties with the coloured grape juice constitute a separated subgroup. This characteristic had a dividing role in comparison with the other tested characteristics. Generally speaking, based on the tested characteristics, the new varieties are much closer to the introduced varieties used in hybridization, which was confirmed by the attained goal of the selection: quality improvement compared with the autochthonous varieties.
