Cortical firmness of transgenic PG1-suppressed and ‘Royal Gala’ control fruit harvested from three seasons.A Cortical firmness of wild-type ‘Royal Gala’ (RG) apple fruit and transgenic PG1-suppressed (PG1as) lines in fruiting seasons 1 and 2. Fruit firmness was measured after ripening for 32 weeks at 5°C (n = 4–10 fruit ± Standard Error). B Mean loss of cortical firmness of transgenic PG1-suppressed and ‘Royal Gala’ fruit in season 3 after ripening for 16 weeks at 5°C. (n = 6–10 fruit ± Standard Error). Lines PG1as-41 and PG1as-275 highlighted in black showed the least change in firmness.
