Distribution of phenotypes for fruit quality traits (including fruit development period, fruit weight, fruit diameter, percentage of red skin colour, red in flesh, red around pit, adherence to pit, eating quality), fruit flavour and fruit fibre content measured in 2015 and 2016 on the F1 progeny. Notes: Fruit flavour (1 = sour, 2 = sour-sweet, 3 = water sweet, 4 = sweet, 5 = rich sweet); eating quality (1 = extremely poor, 2 = poor, 3 = fair, 4 = good, 5 = excellent); adherence to pit (1 = freestone, 2 = semi-freestone, 3 = clingstone); red around pit (0 = no red, 1 = red); fruit fibre content (1 = few, 2 = intermediate, 3 = many); red in flesh (0 = no red overlay, 1 = red overlay). The values of the parents ‘Shahong’ (SH) and ‘Hongfurong’ (HFR) are indicated by arrows
