Abstract
Analysis of results of progeny tests of 25-year-old plus trees of English oak halfsibs by growth intensity, stem quality and bark type is presented. Complex evaluation is suggested for evaluation of availability of plus trees. Such approach gives the possibility to divide all variants to two groups: promising (4 progenies) and relatively promising (7 progenies). Unpromising variants were not revealed in the plot. Trees with smooth-cracked bark predominate in 8 variants, and with cracked bark – in four variants. The part of trees with smooth bark is low in all variants and varies from 0 to 12.8 %. High and mediate positive correlation between diameter and bark texture was calculated. Negative correlation between percent of trees with smooth bark and survival of trees in variants (r= -0.70) was calculated.
