Valencian agriculture researchers have launched six specific avocado research lines at the El Instituto Valenciano de Investigaciones Agrarias (IVIA) in Moncada to improve regional crop production, nutritional management, and commercial post-harvest conservation.
Researchers Develop Rootstocks and Biocontrol Agents for Avocado Cultivation
- Agronomic Adaptation: Researchers are employing genetic mutation and transcriptomic studies via irradiation to develop avocado rootstocks capable of surviving high soil salinity in Mediterranean coastal climates.
- Post-Harvest Pathogen Control: Scientific teams are actively isolating fungal strains responsible for fruit rot during storage to design organic biocontrol agents that replace synthetic chemical fungicides.
- Non-Destructive Ripening Metrics: Food scientists are building optical and physical estimation tools to determine exact harvest maturity schedules without damaging saleable fruit tissue.
Genetic Adaptation and Salinity Tolerance in Moncada
Avocado cultivation across the Comunitat Valenciana faces distinct edaphic constraints, notably high soil salinity and fluctuating irrigation water quality. To counter these physiological stressors, Ander Aguado, a graduate in Agricultural Engineering from the Universidad Politécnica de Madrid with a master’s degree in Plant Breeding from the Universitat Politècnica de València (UPV), presented his genetic enhancement framework at IVIA’s recent sectorial roundtable.
Aguado’s methodology involves generating a collection of plant mutants through controlled irradiation procedures. His protocol evaluates salt tolerance across segregating populations of avocado rootstocks while executing transcriptomic analyses—comprehensive studies of messenger RNA transcripts—to map the molecular pathways governing cellular stress responses. Parallel to this, Rodrigo Martín manages an experimental plot in Moncada utilizing Hass varieties grafted onto Duke7 rootstocks.
Martín’s field trials test diverse organic waste materials as slow-release fertilizers, measuring exact mineral uptake efficiencies under Valencian weather parameters.
Nutrient Ratios and Fungal Pathogens Affect Avocado Yield and Quality
Peris tracks how varying soil nitrogen, phosphorus, and potassium ratios influence flower fruit-set rates, final fruit yield, and biochemical ripening curves. Her chemical assays measure mineral content shifts across the mesocarp to correlate tissue composition with storage longevity.
In plant pathology, Belén Ortiz evaluates phytosanitary conditions across regional groves, targeting soil-borne and aerial fungal pathogens responsible for vascular decline and fruit necrosis. Ortiz isolates potential biological control agents—naturally occurring antagonistic microorganisms—to suppress pathogenic fungi without relying on broad-spectrum chemical interventions.
Gianmarco Amorico, an Italian researcher holding a master’s degree in Agricultural Sciences and Technologies from the University of Foggia, examines post-harvest decay etiologies. Amorico studies the epidemiology of fungi causing post-harvest rot, focusing on organic treatments capable of halting mycelial growth during cold storage transit.
Scientists Assess Ripening Stages of Lamb Hass Using Non-Destructive Tools
The sixth investigative branch addresses the post-harvest physiology of the Lamb Hass variety under Valencian environmental pressures. Yanitsa Zehireva, a graduate in Food Science and Technology with a master’s degree in Food Science and Engineering from the UPV, leads evaluations to pinpoint precise harvest windows based on target export markets.
Zehireva’s team is developing non-destructive diagnostic tools—such as near-infrared spectroscopy and acoustic firmness sensors—to estimate internal sugar profiles, dry matter percentage, and ripening stages without puncturing the epicarp.

Future Researcher Training and Institutional Legacy
Beyond crop science, IVIA administers targeted training initiatives designed to cultivate the next generation of agrifood researchers. This educational framework incorporates 30 predoctoral contracts under the Marisa Badenes program, financed by the Conselleria de Agricultura, Agua, Ganadería y Pesca alongside co-financing from the European Social Fund Plus Comunitat Valenciana 2021-2027.
This initiative represents a total projected investment of four million euros. The program honors Marisa Badenes, who passed away in September 2022. Badenes served as a research professor and coordinator of the IVIA Citrus and Plant Production Center, earning international acclaim for her genetic improvement work across stone fruits, persimmons, and kiwis.
