Growth, productivity and heritability of the height of the seed progeny clonal hybrid seed plantation of Scots pine at 7 years of age

Abstract

Conducted studies on growth and productivity of seed progeny clonal hybrid seed plantation of scots pine in the test cultures. Test cultures of scots pine at 7 years of age have high rates of growth. Of the 20 subjects 9 families of offspring grow better monitoring, indicators 11 families below the height control. On the total volume of the trunks of the differences among the seed progenies were significant. The volume of tree trunks in the compartment in only 2 families were below the control variant (ratio of control to 62.8 and 99.8%). In 17 of the 20 families, the volume of trunks in the compar tment exceeds the control by more than 10% (from 111 to 228%). A supply of stem wood of all the families, except two, exceed the control. Also in test cultures determined the heritability of height of seed progeny of scots pine, which amounted to 39.8%.
