Conservation and valorization of genetic diversity within the population of cv. Plavac mali (Vitis Vinifera L.)
Variability within cv. 'Plavac mali' in the preselection of clones is presented here. After the selection and evaluation of divergent vines at the original location (2-3 years), the majority of them were propagated in a homogeneous ex situ plantation (6 vines per mother vine). ELISA test was used to test 84 clonal lines for the presence of six viruses. Only two samples were negative, and the most frequent infection was with Grapevine leafroll-associated virus 3 (91.9 %). Significant agronomic variability among the clonal lines of cv. 'Plavac mali' was also observed. Principal component analysis (PCA) was done in order to differentiate genotypes on the basis of nine agronomic properties. Two factors, PC1 and PC2, can be used to describe 64.80 % of total variability. Total phenolic content in the skin and seeds, as well as the total anthocyanins showed significant variability among 11 selected clonal lines, but also between the two years of research. The obtained results indicate a significant genetic variability within the cv. 'Plavac mali' and they justify further process of selection.
