Growth and state of climatic ecotypes of European spruce in Belarus

Abstract

The results of the assessment of the growth and productivity of six climatic ecotypes (climatypes) of European spruce growing in Belarus are presented, climatypes with low resistance to ulcerative cancer and changed weather and climatic conditions are identified. Breeding inventory of all climatypes was carried out with their distribution by breeding categories. Correlation between the indicators of growth, productivity, resistance, breeding value and weather and climatic factors of the places of origin of seeds has been established. The closest relationship revealed growth rates, resistance to ulcerative cancer and average temperature, as well as with the geographical coordinates of seed harvesting sites was established. The rank assessment of climatic ecotypes of European spruce for the conditions of Belarus in its selection for productivity and sustainability is given.
