Abstract
Growth and quality characteristics of Scots pine sibs and halfsibs progenies were analyzed in 37 years old provenance tests in the Left-bank Forest-Steppe. Growth dynamics of progenies by height and diameter was investigated. Since 3 years old, the growth in height of seed progenies is characterized by high correlation coefficients, but there are no reliable correlations for diameters. Consistently better and consistently worse by growth families are determined. The best and the worst progenies by height are possible to determine just in a few years after planting seedlings for silvicultural area (part of these progenies hereafter pass into the group with average intensity of growth, but the majority retain the status in the age of 36-year-old. Early diagnosis of the progeny status by average diameter was impossible. Some peculiarities of growth inheritance by progeny of maternal and parental provenances are revealed. Halfsibs of Bryansk and Tambov provenances, as well as sibs' progenies of Saratov and Polotsk, Polotsk and Georgian provenances were recognized the most promising by quantitative and qualitative indicators.
