Yield and Quality Attributes of Strawberry Cultivars Grown in Denmark 1990-1991

Abstract

Twelve strawberry cultivars were tested at the Department of Pomology and Vegetables at the Danish Institute of Plant and Soil Science in 1990 and 1991. The chemical composition and physical characteristics were measured and sensory evaluation was carried out at the Department of Food Science and Technology.

Significant differences were found among cultivars for yield, fruit size, soluble solids, titratable acidity, vitamin C, firmness, surface colour and sensory attributes. ‘Elsanta,’ ‘Korona,’ ‘Polka’ and ‘Sima’ were the only cultivars which gave a good crop and fruit size. ‘Polka’ and ‘Douglas’ were sweet cultivars with a strong strawberry flavour; but ‘Polka’ had a low vitamin C content. ‘Dania’ and ‘Elvira’ were very sour cultivars, and ‘Elvira’ had a high content of vitamin C. ‘Hiku,’ ‘Korona’ and ‘Elsanta’ had low titratable acidity and almost no sourness, and ‘Elsanta’ had a high vitamin C content.
