The collection of 57 accessions were planted and characterized under greenhouse. During postharvest the pH, degrees Brix (°Brix), weight loss and color parameters (L*, a*, b*, chromaticity and Hue angle) were evaluated at 0 and 10 days after harvest. The accession showed significant differences (P < 0.01) over all agromorphological traits, and there were differences among genepools classified a priori as cultivated, ruderal, and intermediate populations between cultivated and ruderal. Nine groups of phenotypic diversity were determined. The storage times (0 and 10 days) presented significant differences at all biophysical traits. After 10 days of storage at room temperature (20.6±5°C and 34±10% RH) the °Brix increased from 4.1 to 4.6 and similarly pH from 3.7 to 4.3. Among phenotypic groups and interaction storage times-groups, significant differences were found for °Brix, color coordinates L* and b*, and Hue angle. The differential postharvest changes indicate phenotypic divergences among and within genepools, which can be exploited in the plant breeding programs with regional objectives. Se evaluó la variación fenotípica agromorfológica y cambios biofísicos de frutos después de 10 días de almacenamiento a temperatura ambiente, en una colección de tomate de Oaxaca, México. La colección de 57 colectas fue sembrada y caracterizada bajo invernadero. En poscosecha se evaluó pH, grados Brix, pérdida de peso y parámetros de color (L*, a*, b*, cromaticidad y ángulo Hue) a 0 y 10 días después de la cosecha. Las colectas mostraron diferencias significativas (P < 0,01) en todos los caracteres agromorfológicos y también hubo diferencias significativas entre acervos genéticos preclasificados como cultivados, ruderales e intermedios entre cultivados y ruderales. Nueve grupos de diversidad fenotípica fueron conformados. Se determinaron diferencias significativas entre tiempos de almacenamiento (0 y 10 días) para todas las características biofísicas. Después de 10 días de almacenamiento a temperatura ambiente (20,6±5°C y 34±10% HR), se incrementaron los °Brix de 4,1 a 4,6 y pH de 3,7 a 4,3. Entre grupos fenotípicos e interacción tiempo de almacenamiento-grupos, se determinaron diferencias significativas en °Brix, coordenadas de color L* y b*, y ángulo Hue. Los cambios diferenciales poscosecha indican divergencias fenotípicas entre y dentro de acervos genéticos que pueden explotarse en programas de mejoramiento con objetivos regionales.

| description |
Agromorphological phenotypic variation and postharvest biophysical changes in fruits after 10 days of storage at room temperature were evaluated in a collection of tomatoes from Oaxaca, Mexico. The collection of 57 accessions were planted and characterized under greenhouse. During postharvest the pH, degrees Brix (°Brix), weight loss and color parameters (L*, a*, b*, chromaticity and Hue angle) were evaluated at 0 and 10 days after harvest. The accession showed significant differences (P < 0.01) over all agromorphological traits, and there were differences among genepools classified a priori as cultivated, ruderal, and intermediate populations between cultivated and ruderal. Nine groups of phenotypic diversity were determined. The storage times (0 and 10 days) presented significant differences at all biophysical traits. After 10 days of storage at room temperature (20.6±5°C and 34±10% RH) the °Brix increased from 4.1 to 4.6 and similarly pH from 3.7 to 4.3. Among phenotypic groups and interaction storage times-groups, significant differences were found for °Brix, color coordinates L* and b*, and Hue angle. The differential postharvest changes indicate phenotypic divergences among and within genepools, which can be exploited in the plant breeding programs with regional objectives. |
