“…Previous studies conducted on olive cultivars in different olive growing countries also revealed high polymorphism by using SSR markers and DCA9 primer was found more discriminative for olive, that support the current findings as well (Bandelj et al, 2002;Poljuha et al, 2008;Alba et al, 2009;Abdessemed et al, 2015). Noormohammadi et al (2009) and Muzzalupo et al (2014) also found high polymorphism in olive cultivars with DCA9 marker.…”

“…The identification of olive cultivars and their area of origin are very important in order to expand cultivation of those commercial varieties with superior yields, that are best adapted to specific local environmental conditions (Sarri et al, 2006;Poljuha et al, 2008). The presence of synonymous clones and mislabelling has been reported in olive orchards.…”

“…Poljuha et al (2008) evaluated 27 Croatian olive accessions with 12 microsatellite markers and detected 81 distinct alleles with an average of 6.75 alleles per locus. Their numbers are close to those observed in this study (see Table 4).…”

“…Synonymy in olives is a frequently reported problem (Carriero et al, 2002;Cipriani et al, 2002;Chafari et al, 2008;Khadari et al, 2008;Poljuha et al, 2008;Baldoni et al, 2009;Bracci et al, 2011). Indeed, the lack of an international organization responsible for standardizing names and cultivars and the limited centralization and availability of information about this species, which is associated with the global diffusion of olive plantlets and seedlings, makes the occurrence of synonymy and homonymy even more common now.…”

ABSTRACT. Olive trees have been grown since the beginning of civilization, and the consumption of olives and olive products is increasing worldwide, due to their health benefits and organoleptic qualities. To meet the growing market for olives, commercial cultivation of this species is expanding from traditional areas to new regions. Although the Brazilian olive industry has just begun to be established, breeding programs are already developing cultivars that are more adapted to local conditions. We used 12 microsatellite markers to evaluate 60 olive accessions, including several cultivars that were developed in Brazil. The analyses identified 72 distinct alleles; the largest number of alleles per locus were at the markers Genetic diversity in olive germplasms GAPU 101 and GAPU 71B, which contained 10 and 9 alleles, respectively. The largest allelic diversity and polymorphic information contents were also found at the GAPU 101 and GAPU 71B markers, with values of 0.8399/0.8203 and 0.8117/0.7863, respectively. Additionally, the 12 microsatellite markers generated a cumulative identity probability of 1.51 x 10 -10 , indicating a high level of accuracy of accession identification. The set of markers that we used allowed the identification of 52 of the 60 olive genotypes, in addition to the recognition of several varietal synonyms. The components of a two-dimensional principal coordinate analysis explained 48.6% of the total genetic variation. The results obtained from the microsatellite markers showed a substantial degree of genetic diversity in the olive tree accessions used in Brazil.

In order to evaluate the role of intrinsic characteristics of olive cultivars on dynamics of oil quality parameters changes related to the olive fruit fly (Bactrocera oleae (Gmelin)) attack, two specific olive cultivars were compared, Istarska bjelica and Buža. I. bjelica is characterised by late ripening, a lower flesh/stone mass ratio and higher oleic/linoleic ratio, the total phenols content and oil mass fraction compared to Buža. Oil samples were obtained at two harvesting dates, from fruit lots with 0, 25, 50, 75 and 100% of infestation degree, expressed by mass. Oil and water content in olive paste, as well as total phenols, fatty acids composition and standard chemical and sensorial oil quality parameters were determined. At equal maturity level, the cultivar with a higher oil (24 AE 1% vs. 16 AE 1%) and lower water content (54 AE 2% vs. 61 AE 4%) was more susceptible to hydrolytic degradation, while the one with the lower total phenols content (231 AE 32 vs. 575 AE 124 mg/kg) and oleic/linoleic fatty acid ratio (5.7 vs. 9.1) was more liable to oxidative deterioration of oil. Lower susceptibility to negative flavours formation could be related to the absence of ripening induced by fly attack and less favourable environment for larvae growth (higher total phenols content, lower water content and flesh/stone mass ratio).Practical applications: Understanding the impact of olive fly attack is the basis of scientific and practical interest in the production of olives and olive oil. Different intrinsic characteristics of olive cultivars could lead to different susceptibility to oil quality deterioration caused by olive fly attack, which opens a possibility to adjust and minimise pesticide treatments. Knowledge about this topic could contribute to the reduction of costs of olive pests control, as well as to the improvement of quality and food safety concept in olive oil production.
