Promising native summer apple ( Malus domestica ) cultivars from north‐eastern Anatolia, Turkey

This study was conducted on summer apple ( Malus domestica ) trees growing wild in the Çoruh Valley, north‐eastern Anatolia, Turkey. The research material consisted of uncultivated summer apple trees. Out of 250,10 trees not infected by apple scab ( Venturia ineaqualis ) were selected. Fruit characteristics of these superior types were evaluated. The ranges of fruit characteristics determined for the selected types were: 49.5–152.2 g fruit weight, 42.8–65.3 mm fruit length, 52.3–75.7 mm fruit width, 10.3–13.8% total soluble solids, 4.88–7.44 mg vitamin C/100 g, 0.19–1.43% total acidity (as malic acid), 9.33–12.06% total sugar, and 6.31–8.94% reducing sugar. Some selections ripening in mid July should be compared with common summer apple cultivars for their agronomic characteristics or used as breeding partners for further breeding efforts.
