Abstract: The study was done during 2014-2020 in Dobrudzha Agricultural Institute - General Toshevo. The new triticale cultivar Borislav was compared with the standards AD-7291, Vihren and Rakita, and with the average standard between Vihren and Rakita. The new standard Kolorit and world standard Lasko were also used. Regarding indices days to heading and plant height Borislav fully aligned with the cultivar Rakita, and the number of productive tillers with the new standard Kolorit. By thousand kernel weight, the new triticale cultivar showed very high levels, but they are strongly influenced by environmental conditions. Test weight is to the level of standard varieties and is retained even in unfavorable conditions for triticale growing. The number of grains per spike is not affected largely by the growing conditions and range from 17 to 24. In relation to yield Borislav significantly exceed all standards and average standard with 5.6% over a 7 year period, indicating its extraordinary productivity and opportunity for production of grain triticale.
