Fruit coloration of apple cultivars

One of the most important parameter of apple cultivars is the scale and the intensity of the coloration of fruits. Nowadays amongthe bicolour cultivars those are the most saleable which have the highest and darkest fruit coloration. In our three years old study cultivars bornwith bud mutation and cross breading were examined, which have superior coloration peculiarities than their parental cultivars. According toour results among the observed cultivars the cvs. ’Gala Decarli-Fendeca’, ’Galaval’, ’Wilton’s Red Jonaprince’, ’Early Red One’ and ’RedCap Valtod’ reached favourable high fruit surface colour (80-100%) regardless the vintage effect. Concerning the colour intensity, that is thedarkness of the red colour most of the cultivars (‘Gala Venus Fengal’, ‘Gala Fendeca-Fendeca’, ‘Galaval’, ‘Jeromine’, ‘Red Topaz’, ‘EarlyRed One’, ‘Crimson Crisp’, ‘Wilton’s Red Jonaprince’) showed excellent values (4,5-5,0). Based on the fruit surface colour and the fruitcolour intensity a new index number, the fruit coloration index was created by us, which describes the coloration features in a complex way
