Fig. 2: Distribution of the main soluble sugar contents in fruits within a collection of 154 strawberry varieties in three seasons (2018 spring; 2019 spring; 2019 end).

The concentrations of sucrose, glucose, and fructose were examined by HPLC and expressed in mg/g fresh weight (FW). The means of three biological repeats from 15 ripe fruits per genotype were used for grouping and frequency counting. Arrows indicate three accessions with different sugar contents selected for further study
