Strawberry (Fragaria x ananassa Duch.) is one the most important fruits in the world. Its growth characteristics, yield and quality are severely affected by environmental conditions, cultivation area and cultivar. This study was conducted to evaluate the compatibility and yield comparison of six strawberry cultivars (‘Kordestan’, ‘Parose’, ‘Marak’, ‘Queen’, ‘Selva’ and ‘Camarosa’) in a tropical area known as “Gachsaran” in Iran. This trial was arranged in a completely randomized design. Vegetative and reproductive growth parameters like the number of flowers, fruits, leaves, leaf length and width were measured. In addition, fruit qualitative and quantitative parameters such as fruit volume, yield levels, the total soluble solid (TSS), juice acidity (TA), the sugar-acid ratio (TSS/TA), juice reaction (pH), vitamin C content and fruit firmness were determined. The results of variance analysis showed that the effects of cultivars on all parameters were significant. ʻMarakʼ cultivar had the highest number of flowers, fruits, yield level, leaf length and width, but the highest total soluble solid (TSS), sugar-acid ratio (TSS/TA), and vitamin C content were related to Queen. Total acidity (TA), fruit firmness and juice reaction (pH) were significantly high in ʻCamarosaʼ cultivar compared with the other cultivars.
