Efficiency of Microtubers Application in the Production of Original Potato Seeds

Abstract

The development of the technology of mass microtubers cultivation in vitro based on innovative methods with respect to potato varieties allowed for use in Kazakhstan has an important theoretical and practical significance for the development of seed production in the Republic. The goal is to develop a technology for mass cultivation of potatoes microtubers in vitro based on biotechnology methods and to assess the possibility of their use as a starting material in the seed-growing process of potatoes. Research methods are generally accepted in plant biotechnology. For the first time, studies are carried out on the mass cultivation of microtubers in vitro and their testing in the field, which determines the relevance and scientific novelty. The practical significance of the project is due to the determination of the most optimal timing for in vitro production of microtubers for the original seed production of potatoes in Kazakhstan. It was revealed that the induction of potato microtubers in vitro allows to accumulate and preserve the healthy planting material of valuable varieties during the entire period without additional transplantations, creating a kind of bank, to simplify and reduce the cost of forwarding the planting material. By regulating the photoperiod, lowering the temperature and modifying the nutrient medium, the tuber formation process was induced. A conclusion is made about the possibility of using microtubers as a planting material in the seed production of potatoes.
