Sion and Brant – new cultivars of common (spring) barley (Hordeum Vulgare L.)

Purpose. Comprehensive assessment of the economically valuable characteristics of the source material and creation of highly productive varieties of common (spring) barley (Hordeum vulgare L.) on its basis that meet today's requirements. Methods. Field (conducting phenological observations and records), laboratory (recording grain yield), mathematical and statistical (objective assessment of the obtained experimental data). Results. Directions and results of breeding work done by the scientists of the Institute of Feed Research and Agriculture of Podillia of NAAS on creation of new varieties of common (spring) barley in conditions of increased soil acidity are presented. Conclusions. The Sion common (spring) barley cultivar of the Institute of Feed Research and Agriculture of Podillia of NAAS, included into the State Register of Plant Varieties Suitable for Distribution in Ukraine since 2022 (patent No. 220800 dated 12/13/2022, certificate of state registration of plants No. 220831 dated 12/14/2022), and Brant, included into the State Register of Plant Varieties Suitable for Distribution in Ukraine since 2023 (patent No. 230635 dated 10/27/2023, certificate of state registration of plants No. 230811 dated 10/10/2023), during the years of testing in the experimental fields of the institution (with increased soil acidity) had a yield of 5.02 t/ha for the Sion cultivar, which is 0.89 t/ha (+21.54%) more than the standard, and Brant at 4.97 t/ha, which is 1.20 t/ha (+31.83%) more than the standard. The high level of productivity is confirmed by the results of the qualification examination of the Ukrainian Institute of Plant Variety Examination and is recommended for cultivation in all zones (Steppe, Forest-steppe, Polissya). Along with this, both cultivars are characterized by a complex of economically valuable traits (resistance to lodging, shedding, drought and resistance to major diseases: brown rust, powdery mildew, helminthiasis).
