  ABSTRACT: Two rust fungi, Melampsora larici populina and Melampsora medusae are common in all poplar growing regions worlwide. M. larici populina is native to Eurasia, while M. medusae is endemic to eastern Unated States on Populus deltoides. Poplar leaf rust (Melampsora sp.) is widely spread disease in our country, and can cause significant growing problems. Race that prevails in our growing region is M. Larici populina. This work initiated the research of population composition, i.e. qualitative participation of Melampsora races in popoluation of black poplars hybrid progenies using molecular methods. When five SSR markers were used the results showed that M. larici populina was found in three tested clones, while only M. medusae was determined in clone I-214.

  ABSTRACT: The paper presents the results of poplar plants´ growing on the soil that is not typical for poplar nursery production - on eugley soil. The dia­meter and height increments were examined for five clones of black poplar: ´S1-3´ (P. deltoides Bartr ex Marsh), ´B-17´ (P. deltoides Bartr ex Marsh), ´S6-7 ´(P. deltoides Bartr ex Marsh), ´260/81´(P. deltoides Bartr ex Marsh) and ´155/81´(P. × euramericana (Dode) Guinier). This soil type is characterized by the fact that the layer from the surface down to 60 cm depth, where the lar­gest mass of roots of seedlings is formed, contains the highest percentage of the total content of clay and silt, and the worst water-air conditions. The texture classes by the soil profile downwards were: silty loam, clay loam and loamy sand. In this type of soil, we observed low survival of cuttings of the examined black poplar clones that, at the end of the growing season, ranged from 63.7–69.4%. There was no significant difference in cutting survival among them. The least significant differences test at the level of risk of 5% divided examined clones in two groups by shoot height: clones ´S1-3´and´B-17´with a 194–197 cm and the clones´S6-7´,´260/81´and ´155/81´with a 157–168 cm shoot height. The mean diameters were uniform and varied in the range from 12.1 to 13.5 mm. Diameter and height growth of clones varied depending on clones, and the most of seedlings at the end of the growing season were classi­fied in 2nd(2,01 to 2,50 m) and 3rd(1,51 to 2,00 m) height class. Unsatisfactory cutting survival, height and diameter plants increments and lower dimensions of rooted cuttings at the end of the growing season could be primarily attribu­ted to the relatively bad water and air conditions of eugley soil.
