Abstract

Purpose. To establish the patterns of manifestation of the level of valuable traits of seed productivity and plant height in hybrid lines of Spring Pebble Vetch by determining the plasticity and stability and selection of valuable starting material for selection. Methods. Field method (phenological observations), laboratory method (evaluation of the material under research). Results. High levels of plasticity and stability of samples of Spring Pebble Vetch according to a complex of valuable traints were established (plant height, number of seeds per plant, weight of seeds per plant). Highly plastic on the basis of «plant height» were found hybrid lines from the combinations: Drobynka / Bilotserkivska 7, Bilokvitkova / selection 332/2. The medium-plastic forms Bilokvitkova / k-789, Drobynka / Hybrid 85, Mutant broadleaf / Bilotserkivska 7 were found to be stable. There were identified four highly plastic samples on the basis of «number of seeds per plant», « weight of seeds per plant »: Bilotserkivska 7/ Drobynka, Mutant broadleaf / Bilotserkivska 7, Toplesa / Hybrid 85, selection 332/2 / Bilotserkivska 7. There were found to be stable forms from combinations Drobynka / Bilotserkivska 7, Drobynka / Hybrid 85 and Bilokvitkova / selection 332/2. Conclusions. The plasticity and stability of hybrid lines of Spring Pebble Vetch were evaluated. The results of research were distinguished forms with a high level of plasticity on the sign of «plant height», «number of seeds per plant» and « weight of seeds per plant ». The lines were found plastic in which one of the parental forms are samples Drobinka, Bilotserkivska 7, selection 332/2 and Hybrid 85 with a high manifestation of these features. The Drobinka / Hybrid 85 combination line was allocated, which is a stable complex of valuable traits.
