Intra-varietal variability of the olive cultivar ‘Piculja’

Croatian Adriatic coast is rich in germplasm of local olive (Olea europaea L. subsp. europaea var. europaea) varieties that have not been fully explored yet. One of these varieties, cv. ‘Piculja’, is grown only in the south Dalmatian region (the Dubrovnik-Neretva County in the south of Croatia). The largest concentration of cv. ‘Piculja’ population is on the Island Lastovo. According to Bulić (1921), there is a mention of this cultivar in Dubrovnik area in 1869, and at that time, the Island Lastovo was part of the Dubrovnik Republic. It is a variety characterized by later ripening and extremely lush vertical growth, and its fruits remain on the tree even until the next flowering. Compared to the cv. 'Oblica' it has a greater tolerance on Olive Fruit Curculio (Rhynchites Cribripennis). It is not among the leading cultivars, but besides its significant role in the production of high-quality olive oil, it has also important economic and technological role as a pollinator for other olive varieties. The aim of ‘pilot’ research was to get insight into genetic variability within limited, but hypothetically diverse set of four old trees of ‘Piculja’. Genetic variability within the cultivar may have an important role as a basis for clonal selection, production of reproductive material and clonal recognition. The insight into genetic variability may also contribute to the knowledge of cultivar evolution and development.
