Abstract

Aim. Based on the usage of samples from the buckwheat genus collection, create and evaluate new source material for drought tolerance, productivity, and quality indicators. Methods. Testing, material evaluation, analysis of plants, yield and grain quality were carried out in accordance with the generally accepted methods of the State variety testing. Results. A laboratory and field assessment of the initial parental forms selected from the collection of the buckwheat genus, involved in hybridization and hybrid combinations based on them based on drought tolerance in the conditions of Podilskyi State Agrarian and Engineering University during 2006–2019 was carried out. It was revealed that the donors for creating new source material on the basis of drought tolerance are the varieties Skorostyhla 86, Smuglianka, Kazanka, Alyonushka, and Veselka. Buckwheat numbers 7/07, 8/07, 2/07, 24/06 have a vegetation period shorter by 5–12 days, drought tolerance 35,4–47,3 % higher, 0,3–0,7 t higher / ha grain yield and high quality indicators compared with the standard Victoria variety. Conclusions. Selected samples with economically valuable traits (7/06, 4/07, 23/06, 5/07, 6/07, 16/07, 15/07, 25/06, 24/06, 22/06) use in breeding programs to create more drought-resistant buckwheat varieties with high yield and grain quality.

Keywords: buckwheat, selection, drought tolerance, express method, productivity and quality indicators.
