Sažetak
Croatia excels in a valuable and rich, but insufficiently investigated olive biodiversity. Significant efforts have been made in the last decade to collect national genetic resources to ensure their long-term conservation in ex situ collections, and thus, their sustainable management. In Croatia there are four ex situ olive germplasm collections, with 88 accessions officially registered in the Croatian Plant Genetic Resources Database. In all countries with centuries-long tradition of olive growing, there are numerous traditional cultivars, as well as a pronounced problem of homonymy, synonymy and intravarietal variability. The aim of this study, carried out within the National programme for conservation and sustainable use of plant genetic resources for food and agriculture, was to characterize the collections and to assess the genetic diversity of collected olive germplasm. We genotyped 69 accessions of 39 traditional cultivars, along with five introduced cultivars, using 14 polymorphic SSR markers. The number of distinct genotypes, duplicated accessions, and the cases of homonymy and synonymy have been determined and the genetic structure and relationships among Croatian traditional olive cultivars have been accessed. Results obtained in this study can be used for germplasm conservation, breeding programs, nursery production improvement and for optimizing a national strategy for the management of olive genetic resources.
