Aim. To evaluate collection winter triticale accessions of different eco-geographical origins for grain yield and environmental plasticity and stability for their further use as starting materials to develop highly adaptable varieties.

Results and Discussion. The study was carried out at the Department of Breeding of Forage, Cereal Spiked and Industrial Crops of the Institute of Feed Research and Agriculture of Podillia of NAAS in 2021-2023. Forty collection winter triticale accessions of different eco-geographical origins from the collection of the National Center for Plant Genetic Resources of Ukraine were studied. The grain yield of the studied accessions varied both by years and by genotype: the maximum yield was harvested in 2023 (9.0 t/ha, with the mean of 6.66 t/ha); the minimum – in 2021 (3.40 t/ha, with the mean of 5.49 t/ha). Accessions characterized by an increase in grain productivity due to improved growing conditions (bi>1.0) and mean yield exceeding the average in the experiment were identified: ‘Bohodarske’, ‘Remiko’, ‘Nyna’, ‘Amos’, ‘Hermes’, ‘AD 256’, ‘Navarro’, ‘Beta’, ‘Skyf’, ‘Dinaro’, ‘Desiatynne’, ‘Pavlodarskyi’, ‘Aliko’, and ‘Yaroslava’. Accessions with high homeostaticity and low variability were also identified: ‘Nykanor’, ‘Salto’, and ‘Beta’.

Conclusions. Based on the results of the evaluation of collection winter triticale accessions, accessions with high homeostaticity and low variability were identified: ‘Nykanor’, ‘Salto’, and ‘Beta’. Accessions with the highest breeding value were also identified: ‘Nykanor’, ‘Nyna’, ‘Maestro’, ‘Hermes’, ‘Serhii’, ‘Salto’, ‘Beta’, ‘Buket’, and ‘Yaroslava’. These accessions may have high potential grain productivity and respond positively to improved growing conditions, so they should be used as parents in hybridization to create highly adaptable winter triticale varieties.
