“…The use of virus-free seed potatoes is an important measure to solve this critical problem and improve yields, and virus-free seed potatoes are generally divided into two levels: pre-elite seed and certified seed. With the promotion of potato detoxification technology and the gradual increase in the area of virus-free potatoes, research on virusfree potatoes is increasing but mainly focuses on tissue culture technology of virus-free seedlings and the production of miniature potatoes (pre-elite seeds) [13][14][15]. However, there is less research on further field expansion technology for pre-elite seeds, resulting in low yields and high costs, which largely limit the application of virus-free seed potatoes.…”

Virus-free seed potatoes are generally divided into pre-elite seeds and certified seeds. To study the differences in dry matter accumulation and distribution between pre-elite seeds and certified seeds through a field randomized block two-factor experiment, pre-elite seeds and certified seeds of four varieties were selected to explore the differences in growth characteristics between the two levels of virus-free potatoes and to find a way to improve potato seed expansion efficiency. The results showed that the growth process of pre-elite seeds was slower and the growth period was longer than certified seeds. The dry matter accumulation of pre-elite seeds in various organs was lower than in certified seeds, and the distribution ratio in the roots and stems of each variety was also lower than the certified seed, while there was no significant difference in the leaf and tuber distribution ratio. The average dry matter accumulation rate in both pre-elite and certified seeds was sorted by size of tubers > leaves > stems > roots; however, it was significantly lower in pre-elite seeds than in certified seeds. Tuber fresh weight, tuber volume, tuber number, and the theoretical yield of certified seeds were higher than those of pre-elite seeds. Experiments have shown that appropriately prolonging the harvest time of virus-free potatoes, especially pre-elite seeds, and increasing the proportion of dry matter allocated to roots and stems by pre-elite seeds in the early growth stages can effectively increase yield.

Abstract. Recently, the trend of agricultural biologization has been gaining great importance. When cultivating crops, the use of biostimulants helps to improve the environment and produce environmentally friendly products. The purpose of the work is to identify the effectiveness of the use of biostimulants “Epin-extra” and “Zircon” in the cultivation of potatoes on the background of minimal doses of mineral fertilizers. Impact on productivity, morbidity and quality indicators of tubers. The novelty lies in the fact that for the first time in the agroecological conditions of the foothill zone of North Ossetia-Alania, the effectiveness of the use of the “Epin-Extra” and “Zircon” biostimulants on the indicators of productivity and quality of potato varieties was studied. Methods Accounting and observations were carried out according to generally accepted methods described in the “Educational-methodical guide for research in agronomy”. Results. As a result of the use of biostimulants “Epin-extra” and “Zircon” in combination with minimal doses of mineral fertilizers, they contribute to a reduction in the passage of the phenological phases of plants compared to the control by 8–9 days. The processing of potato tubers before planting “Epin-extra” and “Zircon” in combination with mineral fertilizers in minimum doses provided a high level of yield, on the Background 1 + “Epin-extra” variant by varieties: 33.7–39.1 t/ha. The biostimulants “Epin-extra” and “Zircon” possess not only growth-regulating properties, but also inhibit the development of diseases, in particular, increase plant resistance to late blight by 4.6–6.5 %.
