Energy Resource-Saving Technology of Accelerated Potato Seed Breeding in the Forest Steppe of the Novosibirsk Probie

Abstract

The results of comprehensive research in 2017–2020 on the effectiveness of improving the health of new zoned and promising potato varieties of three groups of ripeness in the conditions of leached chernozem of the forest-steppe of the Novosibirsk Ob region are presented. The energy-saving, environmentally friendly technology of accelerated potato seed production was used. It is shown that the recovery from viruses of the planting material provides an increase in the yield of different potato varieties up to 42% relative to the unhealthy background. The high efficiency of accelerated propagation of planting material with the use of modern aeroponic plants in comparison with hydroponic plants, and growing in a greenhouse and open ground, is established. The developed technology makes it possible to increase the energy efficiency coefficient by 40 % and the level of profitability by 32 %.

Innovative approach to advancing technology of fast-paced seed production of potato varieties rejuvenated by method of apical meristem in forest-steppe zone of western Siberia

“…which is below the biological productivity potential of 76 t/ha [1][2][3][4]. The main reasons for the insufficient productivity of this crop are the imperfection of the methods of using chemicals, as well as the system of tillage, the absence of early potato varieties that provide high productivity in combination with good quality, resistance of plants and tubers to diseases, and especially the quality of planting material [5,6]. It is necessary to adapt modern agricultural technologies to natural socio-economic conditions with a high degree of accuracy of technological elements that help reduce the energy intensity of production processes while increasing the economic parameters of technologies in terms of good quality planting material [7][8][9].…”
