Comparative experimental studies of potato varieties in the reproduction of mini-tubers in controlled environment conditions

Reproduction of highly productive potato planting material in a controlled environment creates the necessary conditions for good survival, growth and development, increasing the mass and number of mini-tubers, prolonging the effect of preventing re-infection, and helps reduce the costs of cultivation in open ground. The objects of the study were potato varieties bred by the Siberian Federal Scientific Centre of Agro-BioTechnologies of the Russian Academy of Sciences: Lyubava, Tanai, Kuznechanka, Tuleevsky, Kemerovchanin. The Nevsky variety was taken as the breeding standard. The reproduction of mini-potato tubers was carried out on special agrobiological installations equipped with two-tiered racks, as well as the systems for controlling light and heat conditions, time and volume of irrigation, composition and concentration of the nutrient medium. It was found that all the studied potato varieties are suitable for reproduction under controlled conditions and obtaining high-quality planting material for open ground. Using phenological observations, the fact of the identity of the process of potato reproduction under controlled environmental conditions was established. At the same time, the overall growth rates, duration of the growing season and the yield of varieties had different actual values. Based on experimental data, the duration of the growing season under controlled reproduction conditions was determined: for the Lyubava variety it is 55 days, for the Kemerovchanin, Tanai, Kuznechanka, Tuleevsky, Nevsky varieties – from 60 to 65 days. The height of plants, depending on the variety, reached 30–70 cm. Statistical indicators of the number of tubers, depending on the variety, varied in the range from 2 to 5 pieces, the average fractional composition of mini-tubers was 3–5 cm.
