Andrushko O. The Interrelation between Methods of Basic Material Formation and productivity and Quality of Seed Potato, Obtained from Minitubers

Object of investigation: use in seed-growing minitubers, obtained from plants in vitro. Aim of investigation: development and basing of effective and rational receptions of forming of outgoing material in elite seed-growing on base minitubers, obtained from rendered healthy plants in vitro. Methods of investigation: laying on and comparative estimation. Theoretical and practical results: directed theoretical generalization and new settlement of productivity supporting problem and quality of seed potatoes, got on base minitubers, dependency on forming receptions of outgoing material. To Elite potatoes seed-growing offered a new variety of outgoing material, and by namely minitubers mass 1-15 gr. from rendered healthy plants in vitro and recreation method on their base of elite for tolerant for viral sort infection. Offered an improved potatoes elite recreation scheme on base minitubers. Innovations: set for sort tolerant to viruses equivalence of seed material, formed by tuberous selection from heal thy bushes and clone selection, from minitubers different mass. Degree of innovation: the research results found a production inculcation attached to forming of primary propagation of elite seed-growing into Kamyanska-Buzk closed district Lviv regional. Sphere of utilization: for practical application in elitedivelops of Ukraine.
