Abstract
Abstract The article presents the results of the study of breeding lines of winter hexaploid triticale in the West Kazakhstan Agrarian Technical University. Zhangir Khan. Selected and recommended for inclusion in the competitive variety testing variety samples - carriers of traits important for breeding: high productivity, quality indicators of grain. In terms of yield, they exceeded the performance of grain of the standard triticale variety TI 17. High grain yields were found in the breeding lines (Patriot x Vanguard) (35 c/ha), [(Patriot x Vanguard) x (Niklap x Matyrskoe)] (29.1 c/ha). ha), 9457-4/14 (26.2 centners/ha), 9523-1/14 (23.8 centners/ha), varieties Run (23.7 centners/ha). An assessment of the physical, biochemical qualities of the grain of triticale breeding lines was carried out. The analysis of baking qualities made it possible to identify lines with good baking properties: (Niklap x Victor) x Antey, KS88T, Antey x Mara. The assessment of the technological and flour-grinding and baking qualities of winter triticale grain made it possible to identify samples that, along with technological advantages, have a whole range of economically valuable properties that can become a variety of triticale for baking purposes.
