The presented study analyses the phenological characteristics and yield of the Belarusian potato varieties in comparison to the Zyryanets (st.) variety for 2023 and 2024. By the observation data, the duration of full germination ranged from 31 to 43 days in 2023 but seriously reduced towards 2024. The budding and flowering stages became shorter in 2024. Tops of the studied potato varieties were not as high as that of Zyryanets (st.) in 2023, except for the Manifest variety. The number of stems exceeded the standard in 2023 but in the next year, on the contrary, Zyryanets (st.) demonstrated better results. The yield of potato tubers for the studied varieties was higher than that of Zyryanets (st.) in 2023. In 2024, the Belorusian varieties were identified for potato-tuber dry-rot. By the chemical composition of potato tubers, the studied varieties were identified for the starch content higher than that of Zyryanets (st.) and the level of nitrates and vitamin C within the normal range.
