Three Korean-bred strawberry cultivars 'Maehyang', 'Seolhyang', and 'Keumhyang', and a Japanese cultivar 'Tochiotome' were grown in a greenhouse and their physicochemical characteristics were investigated. Fruit weight of 'Seolhyang' and 'Keumhyang' in the first and second fruit clusters were greater than those of other cultivars and that of 'Tochiotome' was the greatest in the fifth fruit cluster. Fruit firmness generally decreased at later fruit clusters, and was the lowest in 'Seolhyang'. The sugars/organic acids ratios in the first and third fruit clusters of 'Maehyang' were 4.9 and 8.0, respectively, representing the highest values among all cultivars. The ascorbic acid content was the greatest in the second fruit cluster for 'Seolhyang', 'Keumhyang', and 'Tochiotome' cultivars and that of 'Maehyang' was the greatest at the third fruit cluster. The anthocyanin content was higher in later fruit clusters and was the highest in 'Keumhyang' overall. Results indicate that Korean cultivars bred for the plastic protected culture, which are intended for very early harvest, showed more desirable physical characteristics in the first and second fruit clusters, while the content of anthocyanin was greater in the fruits from later fruit clusters.
