Abstract

This study evaluated 24 strawberry genotypes, including 12 parental varieties and 12 progenies, using chemical and sensory analyses to assess fruit quality and panelist preferences. Sugar and organic acid profiles, total  soluble solids, titratable acidity, phenolic content, radical-scavenging activity, and sweetness index were determined. Statistical analyses examined correlations among quality parameters, focusing on the influence of sugars and acids on the Brix/TA ratio. Sensory evaluation confirmed panelists’ perception of sweetness and sourness differences. Progeny cultivars BL34 Sandra, BL29 Nadja, and BL42 Federica showed superior quality; two were registered as new varieties, while one is under registration.
