Which improved varieties of processing yellow peach have been promoted in recent years

In recent years, the improved processing yellow peach varieties that have been promoted mainly include Golden Queen, Zhenghuang 2, Jinxu, Jintong 5, 6, 7, and 9, Mingxing, Dixon, and others.

(1) Golden Queen: bred in New Zealand, the main canning export variety of Australia. The fruit ripens in late September. The average single fruit weight is 125 grams, uniform in size, suitable for processing. Its sugar content is higher than other canning peaches, and the canned product is golden and bright. Under cold storage conditions it can be stored until December, and it is an ideal dual-purpose variety for fresh eating and processing. High and stable yield.

(2) Zhenghuang 2: bred by the Zhengzhou Fruit Research Institute. The fruit is medium to large, with an average fruit weight of 123 grams. The fruit shape is nearly round, the two halves are relatively symmetrical, and the suture line is shallow. The skin is golden yellow with a red blush, the flesh is orange-yellow with no red near the pit, non-melting, the flesh is fine and firm, the juice is moderately abundant, and the flavor is moderately sweet and sour. Soluble solids 9-10%, soluble sugars 7.8%, titratable acid 0.7%. Clingstone. Resistant to storage and transport. It ripens in early July in Tai'an City. The pollen is sterile, so a pollinizer variety should be planted. It bears fruit early and sets fruit well. High yield.

(3) Jinxu: bred by the Institute of Horticulture, Jiangsu Academy of Agricultural Sciences. Large fruit, with an average fruit weight of 134 grams and a maximum fruit weight of 210 grams. The fruit shape is round or oblong. The skin and flesh are golden yellow. The flesh is fine and firm, non-melting, the juice is moderate, and the flavor is moderately sweet and sour. Soluble solids 9-10%, soluble sugars 6.6%, titratable acid 0.4%. Clingstone, small pit. Resistant to storage and transport. The pollen is fertile and abundant. The fruit-setting rate is 57%, and the yielding ability is good. It ripens in mid-July in Tai'an City.

(4) Jintong 5: bred in New Jersey, United States. The fruit is very large, with an average fruit weight of 160 grams and a maximum of 274 grams. The fruit shape is nearly round.

The flesh is golden yellow, non-melting, the flesh is dense, the juice is moderate, the aroma is strong, and the flavor is moderately sweet and sour. Soluble solids 11%, soluble sugars 7%, titratable acid 0.45%. Clingstone, medium-sized pit. Resistant to storage and transport. It ripens in early August in Tai'an City. Self-pollinating, with a high fruit-setting rate and strong yielding ability.

(5) Jintong 7: bred in New Jersey, United States. The fruit is very large, with an average fruit weight of 181 grams and a maximum of 250 grams. The fruit shape is nearly round, and the suture line is wide, shallow, and obvious. The skin is golden yellow to orange-yellow, with a red blush on the fruit surface.
