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