Abstract

The seedlings of Juglans regia L. and Juglans regia L. var Racemosa DC were evaluated for the tendency to apomixis.
The seedlings of Juglans regia L. Which gave 78.8–8I.2% of apomictic nuts were selected.
The apomictic seedlings were obtained.
Apomixis is an important feature of walnut particularly in the northern cultivation areas.
