Objectives

Evaluation at the phenotypic level of olive varieties preserving their intact potential may allow detecting and then exploiting variants of primary interest for the new challenges of agricultural production in a context requiring a higher resilience to climatic variations and the production of functional food. Identification of variants showing interesting phenotypes (disease tolerance, abiotic stress tolerance, peculiar oil composition, new health-valued compounds, new flavors, etc.) will represent the main road towards the revitalization of the olive growing at European and international level.
Initiatives for large-scale phenotyping with predictive value have been independently undertaken by Partners of this Project, but a systematic and thorough trait screening is becoming mandatory to fully assess varietal performance.
Main objectives of this activity include:
- Establishing common protocols for high-throughput phenotyping of olive varieties;
- Constructing a phenotypic database;
- Providing phenotypical information of wild and cultivated olive trees growing under different environmental conditions;
- Characterizing important adaptive traits among the olive genetic resources (i.e. adaptation to biotic and abiotic stresses, high productivity and quality yields);
- Screening and selecting olive germplasm for resistance to drought and/or salinity;
- Comparing methodologies to characterize the level and distribution of varieties related to oil quality profiles
