Article Synopsis
- - Olive cultivation in Croatia is a significant tradition with economic and social benefits, and this study is the most extensive examination of olive genetic diversity in the country, involving 108 tree samples from 27 groves.
- - Researchers used eight microsatellite loci to analyze the genetic diversity of the olive trees, discovering 90 alleles and 74 distinct genotypes that suggest complex relationships among the olive plants, structured into three main gene pools.
- - The study also identified 44 known cultivars and 16 new local olive varieties, highlighting the need to protect local genetic resources and keep conducting research on olive diversity.
A capacity to determine the provenance of high-value food products is of high scientific and economic interest. With the aim to develop a tool for geographical traceability of Croatian extra virgin olive oils (EVOO), multielement composition and C/C isotope ratio in EVOO as well as the geochemistry of the associated soils were analysed in samples collected from three regions along the Croatian Adriatic coast. Soil geochemistry was shown to influence the transfer and elemental composition of EVOO.

Four treatments were applied: rain-fed and three treatments calculated as 50%, 75%, and 100% of the crop's irrigation requirement (Irr). Principal component analysis separated growing seasons (GS) that differed in precipitation.

- The World Olive Germplasm Bank of Córdoba (WOGBC) in Spain is crucial for preserving the diversity of olive varieties, needing accurate identification for effective management.
- This study utilized 96 EST-SNP markers to fingerprint 1,273 olive accessions from 29 countries, identifying 668 unique genotypes, including new entries.
- Findings highlighted both significant genetic diversity and redundancy among cultivars, possibly due to synonymy and homonymy, suggesting ongoing interchange of olive cultivars and emphasizing the need for a standardized naming approach.
