Phyllometric study of some wine grapevine cultivar (vitis vinifera l.) from the Balkan subgroup (subconvarietas balcanica negr.)

Abstract

The aim of investigations was to establish the basic leaf characteristics of grapevine cultivars of balkan subgroup, with the phyllometric researches. Ten cultivars for red wine production (Blatina, Vranec, Kratoshija, Teran, Kadarka, Prokupec, Stanushina, Melnik, Mavrud and Plovdina) and four cultivars for white wine productio (Zilavka, Sipon, Zupljanka and Smederevka) were studied. The established standards has the practical meaning in the description and differeniation of eventual biotypes and clones in the population of this cultivars throught the clonal selection. On the base of obtained results from the cluster analysis of phyllometric parametars the clasification of 14 investigated cultivars was done. According to the values closeness of phyllometric characteristics the cultivars are classified in clusters rom witch can determine the differences or similarities between the ecxaminated cultivars. The cluster analysis are made. For the classification of cultivars in the first cluster analyze we used 19 phyllometric descriptors from the GENRES List of primary descriptors, part II. For the second cluster analyse the parapetars from the "leaf method" are used. According to the phyllometric characteristics in the both cluster analysis very closeness linkage has the cultivars mavrud and plovdina and kratosija and vranec. This means that there lot of common leaf characteristics between these cultivars.
