Abstract Goal. To determine the influence of predecessors on the field germination of winter wheat seeds under conditions of unstable moisture in the Right-Bank Forest-Steppe of Ukraine. Methods. The study of the influence of precursors on the field germination of winter wheat seeds was conducted in the conditions of the private agricultural enterprise «Elit» during 2022–2024, which is located in the zone of unstable moisture of the Right-Bank Forest-Steppe of Ukraine. Field germination was determined as the ratio of the number of seedlings obtained to the number of seeds sown. Results. It was determined that on average for three years for all varieties the field germination was significantly higher after sowing winter wheat on winter rape (89.2 %). The lowest field germination (86.8 %) was after sowing winter wheat on perennial grasses. It was found that field germination significantly depended on varietal characteristics. Under the conditions of almost identical laboratory germination of seeds of varieties, which was in the range of 95–97 %, significantly lower field germination of all varieties was obtained when sown on the predecessor perennial grasses. The field germination of varieties Mulan and Shestopalovka was significantly higher than that of Oranta Odesa variety on all predecessors. Significantly lower field germination for all predecessors was in the variety Oranta Odesa. The study of the factors that influenced the field germination of seeds revealed that the greatest influence was the factor ‘variety’ – 59.1 %, and the factor ‘predecessor’, the influence of which was less and amounted to 28.4 %. The influence of other factors and their interaction was insignificant. Conclusions. It was determined that the field germination of winter wheat seeds depended on both growing conditions and laboratory germination, varietal characteristics and predecessors. The most significant was the influence of the factors ‘variety’ and ‘predecessor’ with an index of 59.1 % and 28.4 %, respectively. It was found that the field germination rate was significantly higher after sowing winter wheat after winter rape (89.2 %), and the lowest field germination rate was after sowing winter wheat after perennial grasses and was 86.8 %.
