Figures & Tables

Biplots detailing variation in the fruit quality data. Trait names denoted as follows: Osc – overall score, App – appearance, Swt – sweetness perception, Acd – acid perception, Mas10 – mass of 10 berries, Mas20 – mass of 20 berries, Flv – flavor score, Txt – texture, Col – color, Sks – skin strength, Red – redness, Brt – brightness, Brx – Brix/total soluble sugars

Pathway analysis influence of different traits on the overall fruit quality score (Osc) in strawberry. Weight of links represents relative association between traits. Solid lines show links between overall score (Osc) and other traits, whereas dashed lines show links between other traits. App – appearance, Swt – Sweetness perception, Acd – acid perception, Flv – flavor score, Txt – texture, Col – color, Unf – Uniformity. Numbers are correlation coefficients

Pathway analysis influence of different traits on the overall fruit quality score (Osc) in raspberry. Note: See Fig. 1

Pathway analysis influence of different traits on the overall fruit quality score (Osc) in blackberry. Note: See Fig. 1

Pathway analysis influence of different traits on the overall fruit quality score (Osc) in blueberry. Weight of links represents relative association between traits. Solid lines show links between overall score (Osc) and other traits, whereas dashed lines show links between other traits. App – appearance, Swt – Sweetness perception, Acd – acid perception, Flv – flavor score, Txt – texture, Col – color, Crp – Crispness. Numbers are correlation coefficients

Significance values associated with berry range, cultivar, supermarket of origin, date before best and country of origin with fruit quality attributes_ P-values associated with a chi2 test comparing two mixed models with and without target variable_ NS denotes non-significant comparisons
