Konovalov D. Optimization of technology to for accelerated reproduction of winter wheat seed basic in Northern Steppes of Ukraine

The dissertation is devoted to solving important scientific task on optimization and development of the basic elements technology to for accelerated reproduction basic in the levels of seeds and of seed production the initial introduction of new high-performance winter wheat varieties with varying degrees of intensity of cultivation. The task resolved through of research on the effects of the weather conditions year, terms of sowing, rates of seeding and foliar of nitrogen fertilizing at different stages of organogenesis on plant growth and development, formation of yield and output conditioned seeds sowing and yield of its properties, multiplication factor on case of winter wheat varieties Smuglyanka (short stemmed, highly intensive) and Podolyanka (tall medium, intense), selection IFRH NAS. On the basis of yield, output of conditioned seed it is proved that to increase the multiplication factor of new high seed winter wheat varieties should begin with the initial selection of numbers and reproduction on the results of two years of study in competitive strain testing department of selection. Nursery trials descendants of PB-1 should lay at the same time with the transfer of new varieties into the State sort testing, breeding into basic research institution and new farms spend of unchecked varieties for rates of seeding reduced (2,5-3,5 million seeds / ha) in combination with the best available and foliar feeding system. In parallel with the basic farms breeding new varieties with lower standards should be carried out, and environmental (manufacturing) Quality test, but with full seeding rate. With all of this taken and was put in the optimization of technology to for accelerated reproduction basic varieties of seed of Podolyanka and Smuglyanka, increase the multiplication factor and the need to bring seeds and planting their area in 2016 under the 300 and 350 thousand/hа. Key words: winter millet, seed, variety, meteorological conditions, agrotechnological factors, seeds multiplication factor, accelerate propagated new varieties.
