Potatoes are of great importance for agricultural production in Russia. One of the main reasons for the decline in potato production in the country is the widespread development of fungal and other diseases during the growing season and storage, caused by the lack of varieties with group resistance and a reduction in the scope of protective measures. The gradual increase in certain diseases is significantly influenced by advanced changes in pathogens, along with the changes in their plasticity, adaptability, and pathogenic properties. The research was carried out at the experimental plot of FAT-AGRO LLC in the Prigorodny District of the Republic of North Ossetia-Alania from 2021 to 2023. Having analyzed potato hybrids, a comparative assessment of their quality and resistance to diseases of various etiologies, as well as to adverse abiotic influence in the foothill regions of the North Caucasus were determined.
Keywords: potato, hybrids, variety, potato late blight, virus, alternaria.
