چکیده
Abstract To arrange a system of virus-free potato seed production in the Sakhalin region, series studies undertaken to come up with method towards material cultivation film-gauze greenhouses. At initial stage, key agrotechnical methods were developed for growing test-tube microplants, including optimal planting plans – 70×15 cm (the highest yield derived from standard mini-tuber fraction pcs/m 2 ), 70×30 (for clone selection); spraying insecticides (Aktellik 3 l/ha, Rogor l/ha) and fungicides (Ridomil 1 kg/ha, Tsineb 2.4 kg/ha) combat agents transmitting viral fungal infections; chlorocholine chloride treatment (1.1%) reduce growth vegetative mass; serological analysis plants latent infection viruses X, Y, S, M, F; burning tops Reglon (2 weeks before harvesting. A set used producing healthy tubers on Timiryazevskoye farm made it possible elite cycle 5 4 years, increase by 57.2%, cost 43.5%. Subsequently, worked out seeds improved based modern breeding varieties phytoregulators (Azolen, Elena, Extrasol, Epin-Extra, Zircon) spray mixtures fungicide Shirlan, contributing an increased 34% efficiency 33%. Under conditions, this provided conditionally net income 450-700 thousand rubles/ha.

And one seed potato can produce approximately only 10 potato tubers. To improve the production system of seed potatoes in Japan, Japanese government established a three-stage propagation system for t...
