Figure 2. Trait distribution for L*, a* and b* parameters measured after 60 minutes of exposure to air.

Figure 2

The panels on the left are for POP_1 (‘Fuji x Pink Lady’), while the panels on the right are for POP_2 (‘Golden Delicious x Braeburn’). The grey bars in each panel represent the data distribution observed, while the black line is the normal fit of data. The x-axis gives the value for the three indexes, while the y-axis plots the number of observations.

The position of the four parental varieties is indicated by four letters: F_’Fuji’, PL_’Pink Lady’, GD_’Golden Delicious’ and B_’Braeburn’.
