| Description: | Introduction: The cuayote, Gonolobus edulis, is a plant endemic to Costa Rica and Panama, which serves as food and has been little studied so far. Objective: To carry out the morphological characterization of the fruits of four cuayote accessions in Costa Rica. Methods: Between September and November 2024, we collected fruits from four accessions of cuayote, from various sites in Costa Rica; we collected between 10 and 26 fruits per accession. We evaluated 16 morphological characteristics of the fruits. Results: Accession 1 had the highest fruit weight (394.3g) and length (171.5mm). Accessions 1 and 2, from higher-altitude rural environments, had greater fruit width (96.8-97.8mm) and thickness (85.3-89.8mm) than accessions 3 and 4, from lower-altitude urban areas (74.7-81.9mm and 70.6-75.6mm, respectively). Accessions 2 and 3 had more longitudinal wings (4.65-5.00) than accessions 1 and 4 (4.00-4.13), while other wing-related traits showed no differences. Accession 2 had the lowest length:width (1.47) and length:thickness (1.66) ratios, while accession 3 had the lowest width:thickness ratio (0.99). Conclusion: Fruit size and shape varied by altitude, with larger, rounder fruits at higher elevations and smaller, more elongated fruits at lower elevations. |
