Abstract

The data on individual variability of Siberian larch cones in field-protective plantations of Shira steppe of Khakasia are presented in the paper. Three forms of cones were revealed according to their colour, such as green-coned, red-coned and transitional forms. The technical germinating capacity and quality of seeds from different forms of cones (green-coned, red-coned and transitionаl) were determined.
