“…In vegetatively propagated plants, such as potato, it is possible to produce a great number of disease-free plants using micropropagation by tissue culture 2014;Ozturk, 2017). These in vitro derived disease-free plants are used to produce minitubers (Mts), which are the initial source (classified as Super Elite seed in Turkey) of seed tuber multiplication program, under controlled greenhouse conditions (Ozturk and Yildirim, 2020). In vivo conditions; variety, plant age, plantation conditions, planting time, planting material, season and method, plant density, growing time, irrigation, fertilization-and harvest density and time factors affect production of Mts (Dimante and Gaile, 2015;Dimante et al, 2019;Farran and Mingo-Castel, 2006;Hossain et al, 2015;Ozkaynak and Samanci, 2005;Ozturk andYildirim, 2010, 2011;Sadawarti et al, 2018;Sharma and Pandey, 2013;Veeken and Lommen, 2009).…”

The aim of this study was to determine the effects of three different minituber (Mt) sizes (large, cutting and small) on the number and yield of minitubers (Mts) in 6 commercial potato varieties. The research was carried out according to the split plot design of greenhouse conditions in the 30x30cm plant density in 2017 and 2018. From potato varieties, Soylu were given the highest values in large and small Mt sizes, the number of Mt per plant and per hectare. Mt weight per plant, average Mt weight and Mt yield per hectare Cevher variety showed better performance than other varieties. Approximately 48-50 % of the Mts obtained in terms of Mt size were determined as Mts of 45-60 mm. The size of the cutting Mt was given a higher yield per hectare and the number of Mts than the others. According to the results of the study, Mts of commercial varieties in greenhouse conditions were planted in 30x30 cm plant density and 90% of them were planted directly in the field (≥ 25mm), firstly. Approximately 700000 Mts can be produced from one hectare greenhouse in the greenhouse production system in narrow plant density.

The aim of the research was to grow potato mini-tubers in two crop rotations of protected ground using micro-plants and micro-tubers in vitro as planting material. The experiments were carried out in 2019-2021 in the Republic of North OssetiaAlania (the North Caucasus). The initial in vitro material was planted in spring (April-June) and summer (August-October) rotations in 5 L pots filled with peat substrate. The pots were placed in polycarbonate-lined greenhouses. The objects for the research were the potato varieties Gulliver, Sadon and Kumach. Microplants (control), standard (> 9 mm) and non-standard (5-9 mm) micro-tubers were used as variants for laying the experiment. According to the results of biometric observations in the period from sprouting to the plants reaching 20 cm, the presence of unevenness in plant height was noted in the variants with the use of micro-tubers. In the spring rotation, the cultivation of mini-tubers from microplants contributed to the formation of 6.9-8.0 pcs/plant with a standard fraction yield of 6.1-7.2 pcs. Productivity in variants with planting micro-tubers of 5-9 mm in size decreased by 1.6-1.9 times compared with micro-plants. In the summer rotation, the plants formed from 3.5 to 6.5 minitubers with a standard seed fraction yield of 53-72 %. Microtubers > 9mm (potato varieties: Gulliver and Kumach) in summer planting were more productive than micro-plants. On average, they formed 6.1-6.7 pcs/plant, which exceeded the control variant by 0.8-2.1 pcs. According to the results of the research, the total number of formed mini-tubers during summer rotation was 1.2-1.4 times lower than during spring rotation. The use of two rotations in the process of growing mini-tubers in protected ground contributed to an increase in the quantitative yield of produced seed material for the growing season by 1.7 times.

The purpose of the research is to study the effect of different planting schemes of the base lines on the quantitative yield of mini-tubers in the conditions of Republic of North Ossetia-Alania. The object of the research was microplants and microtubers of new promising potato varieties Gulliver, Sadon and Varyag. The experiments were carried out in 2020-2022, laid on a peat substrate using planting patterns 25x25 cm in plastic pots, 25x30 and 25x15 cm in the ground. Growing mini-tubers according to the scheme 25x25 cm in pots contributed to the formation of from 139.4 to 155.5 pcs/m2 with a standard seed fraction yield of 88-94%. An increase in the nutrition area as a result of planting the base lines into the soil according to the 25x30 cm scheme reduced the number of formed mini-tubers by 19.4-49,0 pcs/m2 with a standard yield of 77-85%. According to the 25x15 cm scheme, the total yield of mini-tubers increased by 19-35 pieces/m2, but the yield of the standard fraction decreased to 57-74%. In the original seed production of potatoes, an important indicator in the cultivation of mini-tubers is the yield of a fraction of more than 20 mm in transverse diameter. The maximum yield of mini-tubers with such dimensional characteristics was noted when planting micro-plants according to the scheme 25x25 cm - 113.7 pcs/m2. The use of micro-tubers according to this scheme reduced the number of mini-tubers with a fraction of more than 20 mm to 91.7 pcs/m2 or by 19%. As a result of applying the schemes of 25x30 and 25x15 cm, the quantitative yield of mini-tubers with a fraction of more than 20 mm did not depend on the origin of the base lines and amounted to 58.5-65.6 pcs/m2. Based on the studied planting schemes in protected ground in the Republic of North Ossetia-Alania, the maximum yield of mini-tubers with the best dimensional characteristics was obtained as a result of planting the base lines according to the 25x25 cm scheme in plastic pots. Reducing the feeding area according to the 25x15 cm scheme reduced the yield of mini-tubers of a fraction of more than 20 mm by 1.8-1.9 times.
