The analysis of Scotch pine seed quality variability in various populations of Southern Siberia and Mongolia is given in the article. Variability in such indicators as the weight of 1000 seeds, germination energy and technical germination ability is given. Some peculiarities of this variability are revealed. Seed quality variability in the long - term cycle is studied too.
