“…The samples were ranked by environmental plasticity according to the following gradation: 1) b i >1highly plastic, well adapted to unfavourable growing conditions genotype; 2) b i =0 -medium plastic sample; 3) b i <1 -low plastic genotype. Homeostatic (8) and breeding value coefficient (9) were determined according to V. Khangildin & N. Lytvynenko (1981) using the following formulas:…”

“…For successful breeding, positive transgressions obtained in hybrid offspring as a result of the formation of recombinations for individual valuable traits are of practical importance. N. Dubovik et al (2018), studying the elements of wheat ear productivity, pointed out the wide range of transgressive variability, in particular, the frequency of positive transgressions for the number of grains per ear ranged from 16.0 to 62.0%, and for the weight of grains per year from 6.0 to 30.0%. M. Lozinsky & G. Ustinova (2020) note that the maximum frequency of positive transgressions in ear productivity is observed in later generations of hybrids, which in the first generation have a high degree of positive dominance in such important traits as grain weight per ear and number of grains per ear.…”

“…Для проведення вдалого селекційного процесу з пшеницею важливим є розширення бази вихідного матеріалу. За вдалого підбору батьківських пар при залученні до гібридизації сортів різного генетичного і географічного походження в популяціях відбувається формотворення за цінними господарськими ознаками [19][20][21].…”
