Abstract

An assessment was made on the main growth and productivity indicators in half-sibs progeny planta-tions of 18 Robinia pseudoacacia L. clones in the region of Ruse, on (М-I-2 D1 (13)) site, on rich, dry and compacted (Haplic luvisols) grey forest soil, at planting scheme 3.0х1,5 m. The differences in the main inventory indicators, defining the growth and productivity of the progenies of 18 black locust clones, confirm good qualities of the progenies of the Bulgarian clones Pordim-10, Pordim-13, Obretenik-1, Obretenik-6 and Ryahovo-1 and of the Hungarian clones Szajki and Nyirségi. This should be taken into account in the selection of material for establishment of industrial plantations and plantations for bio-mass production, as well as in the choice and performance of tending activities.
