Abstract. The purpose of the research is to study and identify, as a result of ecological assessment in nurseries of the selection process, promising potato samples according to the main economically useful characteristics for the creation of a new early-ripening potato variety suitable for cultivation in the soil and climatic conditions of the Northern region of Russia. Methods. The field method and the method of dispersion analysis were used. Scientific novelty of the research consists in the selection of high-yielding promising breeding material of potatoes at different stages of the breeding process, possessing ecological plasticity, resistance to diseases for the creation of a new mid-early nematode-resistant variety with a yield of at least 35–40 t/ha, adapted to the conditions of the Northern region of Russia. Results. A comprehensive assessment of hybrid potato samples bred by the A. G. Lorkh Federal State Budgetary Scientific Institution All-Russian Research Institute of Crops and Vegetables was carried out in the northern territories of the Arkhangelsk region at the Kholmogorskaya Agrofirm LLC. The studies were conducted during 2018–2024, the weather conditions of the growing seasons varied in temperature and moisture availability. Precipitation was uneven, excessive soil moisture was periodically observed, but due to high temperatures, over-moistening of the soil did not have a negative impact on the growth and development of potatoes. According to the Selyaninov hydrothermal moisture coefficient (HTC) in terms of moisture supply, the vegetation periods of 2018–2021 and 2023 were wet (HTC > 1.5), 2022 was slightly dry (HTC = 1.12), and 2024 was dry (HTC < 1.0). The studies were conducted on single-tuber hybrids with subsequent selection in nurseries of the first and second field generations, preliminary, main and competitive tests. As a result of selection from 730 singletuber hybrids (2018), 2 hybrid samples 2346/3 (Udacha × Gala) with a yield of 31.1 t/ha and 2380/4 (Sudarinya × Labadia) with a yield of 45.0 t/ha were selected in the nursery for competitive testing of the second year (2024). The variety samples showed high resistance to viral diseases, rhizoctonia, macrosporiosis and late blight.
