Quality of strawberries of Italian origin grown in the mountainous region of Rio Grande do Sul

Abstract

Studies that evaluate the quality of the strawberry fruit, depending on the different genetic materials and places of cultivation, are still scarce in Brazil. The objective of this work was to evaluate the quality of fruits of advanced genotypes of strawberry with Italian genetics, in the municipality of Farroupilha, belonging to the Serrana region of Rio Grande do Sul. The experimental design was in randomized blocks, with four replications and 10 plants per plot, in two production cycles, containing 21 treatments in the 2018/2019 cycle and 23 treatments in the 2019/2020 cycle. The variables were quantified: fresh mass of commercial fruits (g fruit -1 ); luminosity and chroma of the epidermis; hue angle; pulp firmness (g); titratable acidity content (g 100g -1 of citric acid); soluble solids content (°Brix) and soluble solids/titratable acidity ratio (SS/AT). Among the genotypes evaluated, the genotypes FRF PIR 075.08, ITA 10.128.09, and FRF FC 104.01, have superior fruit quality, showing greater potential to become recommended cultivars for cultivation in the Serrana region of Rio Grande do Sul, together with the cultivar Pircinque.
