Резюме: The first intensive genetic types of triticale forage grain have been obtained in results of wide breeding activities for cultivar improvement. Since 2000 the research has entered a new stage of serving the grain production in the country under the market economy conditions. The studies have been carried out in demonstration trials conducted by the first in the country private Seed House of Sadovo. Climatic changes related to the increasing frequencies of droughts in many of the grain producing areas in the world as a result of the global warming, set new challenges to the breeders and producers of triticale grain. Under the conditions of water deficit, the market demands require not only preserving, but also increasing the amount of the produced grain.
The presented results of the study carried out on the triticale cultivars Sadovets and Rozhen, refer for a five-year period in average, and, on the new genetic types Musala and Hemus – for a three-year study period in average. Sadovo 1 cultivar was used as a standard. A comparative characteristic of the productivity of triticale cultivars in different regions of the country was made. The results obtained showed the advantages of the studied new triticale cultivars of the rye type, especially concerning their productivity, which exceeded that of the standard by 118.3% for Rozhen and by 124.4% for Musala cultivar, respectively.
The high yields of the new triticale genetic types are an advantage under extreme drought conditions. Triticale cultivars exceed wheat in absolute weight but fall behind in hectoliter weight.
