Apricot Species Resources (germplasm resources of apricot)

has a certain genetic material, in apricot production and breeding has the use of valuable plants in the general term. Apricots originate in the mountains of northern and western China. On the north bank of the Yili River in Xinjiang, the southern slope of Kogurqin Mountain extends westward to Xinyuan County, eastwards to Hocheng County, and large areas of wild apricot forest are found in the mountains of western Sichuan at an altitude of 2700m. Due to the complex terrain, cold climate, arid and windy, the temperature difference between day and night is large, which leads to the formation of the characteristics of apricot cold, drought and barren thin.there are 7 species of apricots in the world, the most distributed in China, mainly the following species: 1. Apricots (Prunus armeniaca L.) Native to North and Northwest China. The fruit is of high economic value, and there are several variants of this species, among them P.armeniaca var.holosericea Batal.), whose fruit is inedable and rarely cultivated, but extremely drought-resistant and cold-resistant and can be used as birch and breeding material.can be divided into 6 species: (1) Central Asian sub-species. (2) European varieties. (3) Iranian Caucasian species group. (4) The group of Yili varieties outside the quasi-Jor. (5) China North China Variety Group. (6) East China Variety Group.2. The north-east apricot (P. mandshurica Koehne) is located in the Far East part of Russia, northeast China, and northern North Korea. The main features are bark wood hydrant, fruit handle is longer, about 1cm. Strong cold resistance, can be used as birch and cold-resistant breeding raw materials.3. Mountain Apricot (P.ansu Kom.) It is located in the humid areas of eastern China and Korea and Japan. This kind of
-resistant fungus
strong ability to fight sexually harmful diseases. Strong adaptability to wet climate. Can be used as a birch of southern apricots.4. Siberian apricots (P.sibirica L.) It is distributed in Siberia, eastern Mongolia, northeast China and north China. This kind is extremely drought-tolerant, cold-resistant, can withstand -50 degrees Celsius of low temperature. The fruit is sour and not edible. Rarely cultivated, generally used in birch or as a raw material for cold-resistant breeding.P.mume Sieb.et Zucc., a near-apricot plant in China's Yangtze River basin, is widely cultivated in China and Japan as fruit trees and ornamental trees. Plums and apricots are easily hybridized. Xiong Yuecheng, Gai County, Liaoning Province, has established a national apricot species resource nursery covering an area of 13.3ha. The collection contains 5 species, more than 460 varieties and types of apricots from all over the country.
