CONTRIBUTION TO THE STUDY OF DEGREE OF HERITABILITY OF PHYSICAL QUALITIES OF BEECH (Fagus moesiaca/Domin, Maly / Czeczott.) sr The source of variability and degree of heritability of physical wood qualities were studied on a sample of 24 beech trees - 6 trees on each of 4 localities in Serbia. All physical characteristics to a great extent (45.32% to 57.46%) varied in dependance on test trees. The variability depending on locality (12.93% to 18.76%) was not confirmed in all tests. The reduction of variability originating from test trees moved for different characteristics from 29.61% to 39.98%, being confirmed in all cases at the level of 0.001 with 20 and 312 DF. Calculation of degree of heritability has shown that each studied physical characteristic of beech wood was to a certain degree genetically controlled. From the material of this testing, degree of heritability (h2) of the studied wood qualities moved from 0.31 to 0.47. 1552101 0351-9147 2025-04-17T12:44:59.282Z 44 yes 46 Ljubisav Marković application/pdf 2805948 https://unilib.phaidrabg.rs/o:7504 no yes 1 70 92000001 1987 71A07 Zbornik radova Instituta za šumarstvo 28-29 179 186 Institut za šumarstvo 1987
