Abstract

The research was carried out in 2012-2018 in test sowings of the Ural Agricultural Research Institute– branch of the FSBSI Ural Federal Agrarian Research Center of the Ural Branch of the Russian Academy of Sciences with the aim to obtain promising high-yielding, locally adapted breeding samples of winter triticale. We used interverietal hybridization and evaluation of hybrids F₁-F₄, selection and sowing of ears and plants in breeding nurseries. Evaluation of promising lines on plots of 5-10 m² according to generally accepted methods. Breeding samples of winter triticale were obtained, the yield of which reached 6.8-7.0 t/ha and was 15-19% higher than the standard - Bashkirskaya korotkostevelnaya (5.9 t/ha). The winter hardiness of the best samples was at the level of 80-90 % and exceeded the standard (72 %) by 12-18 %. Samples were found that exceeded the standard by the number of grains in the ear, the weight of 1000 grains, the ear productivity and the content of raw protein in the grain. The selected hybrid samples are evaluated in a competitive test and propagated in isolated areas.
