'NINGYU': A NEW CULTIVAR WITH HIGH REDUCING SUGAR, ASCORBIC ACID AND ANTIOXIDANT CAPACITY
Ningyu has been released from the breeding programme at Jiangsu Academy of Agricultural Sciences since 2010. It is a new, early fruiting and balanced aroma cultivar with anthracnose resistance, which is derived from Sachinoka × Akihime in 2005. Plant characterization, fruit weight and color, total titrable acidity, organic acid, sugar, ascorbic acid and antioxidant capacity were evaluated. Compared with Sweet Charlie, Ningyu has lower plant height (7.34 cm) and leaf area (21.83 cm2), thinner crown (22.42 cm), slighter leaf weight (0.18 g) and slighter average single fruit weight (21.66 g) at the first cropping, while the average single fruit weight of Sweet Charlie is 27.2 g. Sweet Charlies fruit surface and flesh color are redder (hue angle value smaller) and greater in pigment intensity (chroma value bigger) than Ningyus. Sweet Charlies total titratable acid and citric acid are bigger than Ningyu. There are equal amounts in malic acid between the two cultivars. Ningyu has greater amounts of fructose (148.98 mg/100 g FW), glucose(195.92 mg/100 g FW), reducing sugar (344.91 mg/100 g FW), ascorbic acid (68.9575 mg/100 g FW) and antioxidant capacity (1.433 mmol trolox/100 g FW) than Sweet Charlie.
