Flavanol concentration measured in 2010 in fruit skin and cortex of seven commercial apple cultivars compared with quince, crab apple and two seedlings from the 'Royal Gala' × 'Braeburn' segregating population. The 'Royal Gala' × 'Braeburn' seedlings and cultivars are shown with their LAR1 genotype as in Figure 3. A: catechin, B: procyanidin-B2, C: epicatechin and D: procyanidin oligomers. The concentrations are given in μg/g of fresh weight.
