Abstract
Olive cultivar Zutica is grown on the Montenegrin coast more than 2000 years.
During that period, many different individuals according to the phenotype have evolved due to different environmental conditions.
The level of morphological variation has not been analyzed.
The degree of clonal variation, observed within this cultivar is presented in this paper.
The 23 clones (individuals) from the southern part of the Montenegrin coast, where the cultivar Zutica predominates, were examined.
Out of 22 observed parameters (leaf, internodes, blossom, fruit and endocarp), based on the principal components analysis (PCA) the largest influence on separation of the clones had the characteristics of fruit and endocarp, while the smallest effect had features of leaf.
Based on Squared Euclidean distance (UPGMA method) the dendrogram was constructed, clustering the clones into two main groups with 8 and 13 individuals.
The clones VAL2 with the biggest and DAB1 with the smallest fruits were separated as single clusters.
Among the tested clones there were also recognized those with high oil content (over 21%) which can be used for improvement in oil production.
The investigated clones will be a subject of further research in order to confirm the variability at the molecular level.
