Antioxidant activity of new strawberry clones: June-bearing and ever-bearing.

Strawberry is one of the most commonly eaten berries. Breeding procedures led to the separation of two types of strawberries: June - bearing and Ever-bearing strawberries fruit for about a month and Ever - bearing throughout the growing season. The aim of the project is to compare the antioxidant parameters between both types of strawberries with those of two other dicots (blackberry and red raspberry). The research covered 29 strawberry clones: 10 Ever - bearing and 19 June - bearing, 6 blackberries, and 12 red raspberry. Statistical analysis of the Mann-Whitney test showed that in terms of the tested parameters there are no statistical differences between the two types of strawberries; however, the year-round yield and extended availability of fresh fruit mean that these varieties are gaining more and more interest from producers and consumers. Repeat-fruiting strawberries are statistically more than twice as efficient than traditional varieties, not inferior in taste to traditional varieties.
