Flowering Phenology of Six Seasonal-Flowering Strawberry Cultivars in a Coordinated European Study

The flowering phenology of six genetically distant strawberry cultivars (‘Candonga®’ (ES), ‘Clery’ (IT), ‘Florence’ (UK), ‘Frida’ (NO), ‘Gariguette’ (FR), and ‘Sonata’ (NL)) was studied for 3 years in relation to climatic parameters open-field cultivation at three locations (Norway, Poland, Germany) soil-less two (Italy, France), covering a distance 16 degrees latitude. This proved be useful approach unravelling the adaptation plasticity genotypes their suitability both profitable as breeding pedigree. Despite intercorrelated character variables, observed results highlight importance global radiation powerful modifying phenological factor strawberry. Generally, early flower initiation associated with elevated temperature radiation. revealed highest dependency on initiation, while least affected by In general, periods preceding following had stronger positive effect number flowers than crowns, especially under conditions. influence these factors highly variable across cultivars: ‘Clery’, ‘Florence’, were most affected, influenced.
