Peach variety Qin Guan

Shaanxi Fruit Tree Research Institute Yuan Wuzhou et al., parent capital crown × chicken crown. It was hybridized in 1957, selected in 1966 and named in 1970. He participated in the regional trial of Big Apple and won the second prize of the National Invention Award in 1988. It is widely distributed in China and cultivated more in Northwest China.

The fruit is conical and weighs about 200 Mel 250 grams; the background is yellow and green, with dark red and intermittent red stripes on the sunny side, often with white stripes, which can reach overall dark red when fully ripe in the higher altitude areas of the northwest, but it is difficult to color in the low altitude plain areas; the fruit surface is smooth, waxy, obvious, and the pericarp is thicker and tough. The flesh is milky white, the meat is crisp and slightly dense, the juice is more, the flavor is sour and sweet, and the soluble solids are 11%, 16% (different regions vary greatly), and the fresh food quality is high at the beginning of picking. The growth potential is strong, and the tree posture is open. It begins to bear fruit early, and the seedlings bear fruit 2-3 years after planting. The main fruiting parts are long fruit branches and axillary flower buds in the first fruit. after the full fruit stage, short fruit branches and axillary flower buds bear fruit mainly, with high fruit setting rate, strong ability of self-pollination, early fruit and high yield. It matured in the northwest, the north of North China and the west of Liaoning in mid-October. The fruit is very resistant to storage and can be stored in a semi-underground soil cellar until May of the following year.

The cultivation quality of Qin Guan is better in the area with higher altitude and large temperature difference between day and night, but the fruit quality is poor in the plain with low altitude, hot and humid climate and poor light. Cultivation and management is relatively easy. During the period of young trees, we should lay a solid skeleton foundation for high yield. After a large number of fruits, we should pay special attention to maintain a suitable load, strengthen fertilizer and water, and ensure high and stable yield.

Qin Guan has the outstanding advantages of early fruiting, high yield and fruit storage resistance, so it is very popular in the newly developed areas of apple, but the fruit flavor is not good and the coloring is not ideal enough, so it is difficult to be used as a high-grade product @ # @ 136 fruits @. In the past ten years, under the condition that the fruits of excellent varieties continue to occupy the market, the sale of Qin Guan has been difficult, and its cultivation has been affected, so it can be cultivated as an auxiliary variety or pollinated variety in the new development area.
