“…3) showed significant differences amongst accessions, especially for parameters FWe, FPW, FNo, FDM, FWC, FPP and P/E, and differences for EWe were highly significant. The fruit characteristics, especially the fruit pulp, indicated not only the high diversity amongst 'Žutica' accessions, but also the impact of the year of sampling within each accession, which was found in earlier research on the two-year cycle of olive bearing [Lavee and Wonder 2004, Trentacoste et al 2010, Trentacoste and Puertas 2011.…”

“…Characterization of the material using multivariate analyses (PCA and cluster analysis) enabled us to gain an overall view of variability amongst the accessions based on the complete range of traits. PCA has been used in the evaluation of olive germplasm [Cantini et al 1999, Trentacoste andPuertas 2011] and in analysis of olive genetic diversity [Bandelj et al 2002, Hosseini-Mazinani et al 2004, Hannachi et al 2008, Uylaşer et al 2008, Strikic et al 2009, Zaher et al 2011. The PCA used in our work showed that more than 91% of observed variability was explained with the first three components, similar to the results reported by Cantini et al [1999] for olive accessions in the germplasm collection in Italy.…”

“…Morphological and agronomic characteristics have been used in many countries [Cantini et al 1999;Barranco et al 2000, Rotondi et al 2003, Trentacoste and Puertas 2011] to identify and characterize cultivated olives, as essential components in evaluating genetic material. A number of clones with different morphological and agronomic characteristics can be found within a single olive variety [Bellini et al 2008], revealing intra-varietal polymorphism [Lopes et al 2004].…”

ABSTRACT'Žutica' is the most widespread olive variety of Montenegro, accounting for as much as 98% of olive trees in the southern part of Montenegrin coastal area -Bar subarea. The primary purpose of variety 'Žutica' is olive oil production due to its small fruits and high oil content, although it is also much appreciated as a table olive, prepared in local ways as green and black. As 'Žutica' is an old olive variety there are some phenotypic differences recorded in the fruit properties. Here we evaluated 22 accessions from the area of Bar and Ulcinj, where this variety is very widespread (almost mono-varietal), for 34 parameters of the fruit and endocarp. Significant differences in fruit properties were observed in the accessions. Average fruit size in nine accessions was above 3.5 g and in two accessions more than 4.0 g. Number of fruits per kg ranged from 224 to 330. Cluster analysis and principal component analysis (PCA) were used to group the accessions and evaluate the morphological variability. The accessions clustered into two groups, with two off group accessions of the highest fruit weight. The results showed differences among individuals, especially for large fruit accessions that should be investigated further.

“…In a previous study conducted to evaluate morphological and agronomic characteristics of an olive germplasm collection in Argentina, the olive cultivar Gordal Sevillana with the highest fresh fruit weight and fresh stone weight introduced from Spain was also characterized as a distinct cultivar from other accessions (Trentacoste and Puertas, 2011). The cultivar Gordales evaluated in this study was also introduced from Spain to Turkey, and it may be closely related to Gordal Sevillana.…”

Identification of molecular markers associated with fruit traits in olive and assessment of olive core collection with AFLP markers and fruit traits

et al. 2015

ABSTRACT. The purpose of this study was to characterize olive core collection with amplified fragment length polymorphism (AFLP) markers and fruit traits and to determine AFLP markers significantly associated with these fruit characters in olive. A total of 168 polymorphic AFLP markers generated by five primer combinations and nine fruit traits were used to characterize relationships between 18 olive cultivars. Although all olive cultivars were discriminated from each other by either AFLP markers (<0.75 similarity level) or fruit traits, clustering based on the AFLP markers and fruit traits was not significantly correlated (r = 0.13). Partial clustering of olive cultivars by AFLP markers according to their geographical origin was observed. Associations of AFLP markers with fruits were determined using a multiple-regression analysis with stepwise addition of AFLP markers. Significant associations between eight AFLP markers and fruit traits were identified. While five AFLP markers demonstrated significant negative correlation with fruit and stone weight, width and length and total polyphenols (P < 0.05), three AFLP markers displayed significant positive correlation with α-tocopherol and γ-tocopherol (P < 0.01). This is the first report on the association of molecular markers with fruit traits in olive. Molecular markers associated with morphological and agronomic traits could be utilized for the breeding of olive cultivars. However, the association power of these markers needs to be confirmed in larger populations, and highly correlated markers should then be converted to PCR-based DNA markers such as sequence-characterized amplified region markers for better utilization.

“…‘Arauco’ is well adapted to local conditions and is mainly present in old plantations with traditional management (i.e. low density and manual harvest) . It is mainly destined for the production of table olives, although recent studies have revealed the high quality of its oil in terms of fatty acid profile and antioxidant compounds .…”

Olive oil characterization of cv. ‘Arauco’ harvested at different times in areas with early frost in Mendoza, Argentina

et al. 2019

BACKGROUND ‘Arauco’ is the only autochthonous olive cultivar from Argentina. Little has been reported so far regarding the management of this crop. In this work, variations in fruit and chemical characteristics of olives harvested over a wide range of dates and seasons are reported for this cultivar at two sites in Mendoza province in central west Argentina. RESULTS During the harvest periods studied, fruit oil content on a dry basis remained at its maximum and was stable, but fruit oil content on fresh basis increased as water content decreased with delay in harvest date. Harvest date affected the maturity index of fruits as well as the oxidative stability and phenolic content of oil. In contrast, the fatty acid profile was not consistently affected by harvest date. Environmental conditions, mainly the occurrence and intensity of frosts, strongly influenced oil quality as well as maturity with delay in harvest date. CONCLUSION The most appropriate harvest time to obtain Arauco oil with a high oil yield and good chemical quality was before mid‐May and with maturity index lower than 2. Fruits harvested after mid‐May were exposed to minimum temperatures between −1.2 °C and − 4.0 °C, producing oil with low phenolic compounds and oxidative stability. © 2019 Society of Chemical Industry
