This paper presents the results of the analysis of variability of 8 analysed morphometric parameters in two-year old seedlings of 13 half-sib lines at different levels. The recorded genetic and nongenetic variability is conditioned by numerous different factors. The important causes of genetic variability are: partial incompatibility of parent trees, partial hybrid sterility, predominant inbreeding, frequent mutations with the growth of parent trees, very abundant gene recombinations, etc. The causes of nongenetic seedling variability are: external environmental conditions (soil, humidity, conditions of cultivation, silvicultural interventions, etc.) and the internal or the somatic environment of seedling.
