Data are tabulated on biochemical characteristics of fruit (dry matter content, total acidity and total sugar contents, and ascorbic acid content). Descriptions are provided for Toros, Borovitskaya, Bogota and Dukat strawberries. Information is included on plant morphology, frost resistance, crop yield, resistance to fungal diseases, nutritive value and flavour.
