| Sumario: | Background of the study - In order to increase exportation in a worldwide context and maintain optimum fruit quality for consumers, we must pay special attention to postharvest behavior and shelf-life during the process of fruit storage and transportation. Apricot (Prunus armeniaea L.) fruits are characterized by a short market life compared to other temperate fruit species such as peaches or plums. For this reason, a long shelf-life is an important new objective in apricot breeding programs. Objective - The aim of this work was to evaluate the postharvest behavior and shelf-life period in different apricot varieties. Methods - Sixteen varieties from the CEBAS-CSIC breeding program were subjected to different post-harvest treatments, combining cold storage periods at 1°C and standard room temperature conditions at 20°C to simulate the usual marketing channels. Fruit weight loss, skin and flesh colour, firmness, soluble solids content, malic acid content and the soluble sol-ids-titratable acidity ratio were monitored for each variety. Additionally, the visual appearance, fruit texture and flavor were determined as the main sensorial traits. Results - Significant differences among varieties were observed, indicating that postharvest behavior is genotype-dependent. These results made it possible to identify several apricot varieties with a long shelf-life period of up to 35 days: 'Deseo', 'Dorada', 'Maravilla', 'Murciana' and 'Rosa'. Conclusion - Among the varieties studied, 'Deseo', 'Dorada', 'Maravilla', 'Murciana' and 'Rosa' are the most suitable for prolonged storage and long-distance export. These characteristics determine the commercial interest of these apricot varieties together with their potential use as progenitors in breeding programs. |
