Introduction. Shanxi province is one of the main walnut production areas inthe North of China. The cultivated species mainly belong to a Chinese walnut treepopulation, named ‘Mian Hetao’ (Juglans regia L.), which reproduces fromseedlings. Although the walnut apomixis characteristics were discovered very early andhave an important breeding value, this variety has not yet been reported as an importantbreeding resource. Cultivar origin. ‘Qinquan 1’ is a new cultivar of walnuttree (Juglans regia L.), selected in 1982 from walnut seedling resourcesin the department of Shanxi, in the North of China. This cultivar is characterized byapomixis, the ratio of which can reach 24.7%. After more than 20 years of selection andmany local experiments, its characteristics were given and the cultivar was certificatedin March 2007. Cultivar characteristics. Characteristics of ‘Qinquan 1’fruits, trees, development stages, production and the apomixis rate are given. Maincultural techniques. Many characteristics of this new cultivar are suitable forits growth in the middle or south Loess Highlands (China), where the annual averagetemperature is 9~13 °C and rainfall is above 450 mm. The cultivar is also cultivable inthe North of China where the soil and climate conditions resemble those of the originalarea. Other recommendations are given for improving the ‘Qinquan 1’ tree growth.
