Резюме: The study was done during 2012-2020 in Dobrudzha Agricultural Institute - General Toshevo. The new triticale cultivar Doni 52 compared with the standards AD-7291, Vihren and Rakita, and the average standard between Vihren and Rakita. The new standard Kolorit and world standard Lasko were also used. In terms of indexes days to heading, plant height and number of productive tillers, Doni 52 fully aligned with the cultivar Rakita. By thousand kernel weight, the new triticale cultivar is on the level of Kolorit and Lasko. The test weight is significantly higher than that of standard varieties and is retained even in unfavourable conditions for triticale growing. The number of grains per spike has was significantly influenced by the growing conditions and ranges from 20 to 36, but is higher than that of the standard varieties. In terms of yield Doni 52 exceed all standards and also the average standard with 11.9% for 9 years, showing its exceptional productivity and stability.
