Special Issue Information

Dear Colleagues,

The cultivated olive (Olea europaea L.) is one of the most representative and economically important crops in the Mediterranean region. The olive sector is currently experiencing a profound crisis due to the ever-changing environmental and climatic conditions and new phytosanitary emergencies. From this perspective derives the urgency to have alternative olive varieties that are resilient, adapted and plastic, and able to guarantee early fruiting and entry into production, as well as plant architecture suitable for fully mechanizing olive harvesting and pruning, low susceptibility to parasites and harmful pathogens, high productivity and oil yield, high content of secondary bioactive compounds, and high nutritional and sensory quality of olive oil.

Due to the prevalent out-crossing nature of the species, the olive still has a certain genetic variability to exploit in breeding programs. Accurate prospecting of olive-growing areas could highlight the presence of ancient, or wild olive trees, not traced back to previously cataloged varieties. In addition, it is possible to develop new varieties of olive trees starting from the crossing between known and genetically compatible genotypes to introduce improving characteristics.

This Special Issue welcomes scientific articles concerning the evaluation and selection of olive tree genotypes through agronomic, physiological, biochemical, and technological approaches in order to build a multidisciplinary network for a modern, more biodiverse, and competitive olive growing, with an increase in environmental sustainability and the safeguarding of product quality.

Modeling phenological phases in a Mediterranean environment often implies tangible challenges to reconstructing regional trends over heterogenous areas using limited and scattered observations. The present investigation aimed to project phenological phases (i.e., sprouting, blooming, and pit hardening) for early and mid–late olive cultivars in the Mediterranean, comparing two phenological modeling approaches. Phenoflex is a rather integrated but data-demanding model, while a combined model of chill and anti-chill days and growing degree days (CAC_GDD) offers a more parsimonious and general approach in terms of data requirements for parameterization. We gathered phenological observations from nine experimental sites in Italy and temperature timeseries from the European Centre for Medium-Range Weather Forecasts, Reanalysis v5. The best performances of the CAC_GDD (RMSE: 4 days) and PhenoFlex models (RMSE: 5–9.5 days) were identified for the blooming and sprouting phases of mid–late cultivars, respectively. The CAC_GDD model was better suited to our experimental conditions for projecting pit hardening and blooming dates (correlation: 0.80 and 0.70, normalized RMSE: 0.6 and 0.8, normalized standard deviation: 0.9 and 1.0). The optimization of the principal parameters confirmed that the mid–late cultivars were more adaptable to thermal variability. The spatial distribution illustrated the near synchrony of blooming dates between the early and mid–late cultivars compared to other phases. Full article

A prospecting campaign in the Maltese Islands has ensured the survival of several ancient olive trees (Olea europaea L.), genetically distant from known cultivars. Most of these plants were abandoned or partially cultivated. A two-year evaluation of fruit characteristics and compositions was performed on samples collected from the main representatives of these indigenous genotypes. Analyses were carried out using Gas Chromatography, High-Performance Liquid Chromatography and Near Infrared Spectrometry. Among the fruit samples, a wide range of variations was observed. Some of the genotypes showed fruit traits suitable for table olive production. This is the case of samples with a pulp/pit ratio higher than four, such as 1Wardija, 1Caritas, 1Plattini, 1Bingemma Malta and 3Loretu, whilst 1Bidni, 1Mellieha, 2Qnotta, 3Loretu, 1Bingemma Malta and 1Caritas were suitable for dual purpose. The total phenol content ranged from 6.3 (1Wardija) to 117.9 (2Mtarfa) g/kg of fresh pulp. The average percentage of MUFA was quite low for most of the varieties. These genotypes, which presumably originated in the Maltese Islands and are well adapted to the local pedo-climatic conditions, are being propagated for the following evaluation of their bio-agronomical performance (production, suitability to intensive cultivation, environmental sustainability, product quality, etc.). The purpose is to select, among these local genotypes, the most outstanding varieties, in terms of phenolic and FA profile and agronomical potential, to spread into cultivation, thereby contributing to an increase in the quality of the local table and olive oil production, strongly linked to the territory.
