It was noted that in terms of the duration of the growing season, the variety MIP Palianytsia myronivska and the line Erythrospermum 60724 were considered to be more early maturing. The date of the beginning of ear emergence for a given genotype varied depending on: the previos crops – by 2–4 days, the sowing date – by 1–4 days. The highest plant height was observed after green manure, the lowest – after sunflower. The maximum yield of winter wheat varieties was 7.83 t/ha after green manure, the minimum was 4.44 t/ha after sunflower. Higher yields were obtained when sowing on September 25. The variety MIP Aurica and the lines Lutescens 60293 and Lutescens 60702 were characterized by higher yields (6.67–7.08 t/ha). The yield of winter wheat mainly depended on the previos crop (65.3 %) and the variety (4.9 %), as well as on unaccounted factors (11.1 %). Other interactions between factors had a negligible effect on yield. A greater response to changes in growing conditions was observed in the line Lutescens 60702 and the variety MIP Aurica. The variety Podolyanka and the lines Lutescens 37548, Lutescens 60400 and Erythrospermum 60667 showed a lesser response. In the line Lutescens 60293, yield varied in direct proportion to agrotechnical conditions (bi = 1.00).
