The object of research is the collection and seeding of synthetic varieties of buckwheat. The purpose of the work is to create high-yielding early-settled determinative and middle-aged varieties of buckwheat with improved architectonics of plants resistant to stress conditions. Methods of research: hybridization, polycrost test, self-pollination with tetraploid buckwheat isolation, group selection by direct signs and selection indexes, negative selection for determinism. Results of the study - in the obtained hybrids F2 negative selection for determinism was conducted. Formed and multiplied 10 new varieties - populations and 3 varieties - synthetics. In the control nursery, based on the level of overall combining ability, 120 maternal components were evaluated, of which 30 hybrids were selected, which could be used as components of synthetic varieties. Of the 13 breeding rooms in the competitive variety trial, a significant increase in yields (from 0.37 to 1.15 t / ha) over the national standards was provided by 8 selection rooms. Reproduction of seeds of new regionalized varieties of buckwheat Olga (elite) and Ruta variety (РР2). Prepared for the transfer to the State variety assortment of buckwheat variety called Pokrovsky.
