Characteristics of economically valuable traits of synthetic hexaploid of spring common wheat lines CIMMYT in the Central region of the Non-Blackearth part of Russia

The current paper has presented the study results of 14 synthetic spring wheat lines developed at the International Maize and Wheat Improvement Center (CIMMYT). The study was conducted at the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy. Field trials were carried out at the field experimental station in 2022–2023. Agricultural technology was typical for the zone. The plot area was 1 m2 with a threefold sequence. Weather data were obtained from the V. A. Mikhelson Meteorological Observatory. There has been found that the spring wheat lines 70, 220 and 221 are early maturing under the conditions of the Central Region of Non-Black Earth Area. The rest lines are middle maturing, with 7–10 days later with the standard variety. The lines 70, 178, 215 and 220 are resistant to powdery mildew and brown rust. The lines 147, 217 and 223 are the most stable in productivity. A positive correlation was identified between yield and the number of grains per ear (r = 0.56), as well as between yield and grain weight per ear (r = 0.83*). Additionally, a moderate positive correlation was observed between the length of the growing season and the weight of 1000 grains (r = 0.57*).
