Resumen
Introduction. The preliminary study of the post-harvest quality of the fruit from strawberry cultivars in a new growing region is necessary for both farmers and consumers. The objective of the present study was to evaluate strawberry cultivars at different harvest times with regard to fruit quality aiming at the selection of possible parents for breeding programs for cultivation in the tropical humid conditions of the city Datas, in Minas Gerais State (Brazil), and in other regions with similar soil-climatic conditions. Materials and methods. The strawberry fields were cultivated on the Mape Frutas Farm, located in the city of Datas-MG. Eight cultivars ('Aromas', 'Camarosa', 'Campinas', 'Diamante', 'Dover', 'Festival', 'Oso Grande', and 'Toyonoka') were assessed in a randomized block design with a split-plot in time. Four replicates and three harvest times (June, August, and October 2012) were evaluated. Fruit from the different cultivars were analyzed for their physicochemical and antioxidant properties. Results and discussion. There was a genetic variability and the predominance of genetic factors over environmental effects for the evaluated traits. Fruits harvested at the end of the crop cycle (October) had the highest levels of total reducing sugars, vitamin C, phenols, anthocyanins, carotenoids, soluble solids, and total antioxidant activity. Cultivars Camarosa, Festival, and Toyonoka showed better fruit quality. Conclusion. Based on the genetic dissimilarity and fruit quality, the cross between 'Toyonoka' and 'Camarosa' or 'Festival' is indicated for the genetic improvement of strawberry in the region and other places with similar soil-climatic conditions. © Cirad/EDP Sciences 2016. 71 3 151 160
