Aim. Triticale is one of the main grain crops of the Republic of Belarus. Further progress in the selection of this culture involves the accelerated creation of highly productive early ripening varieties resistant to abiotic and biotic factors. The method of induced androgenesis in vitro makes it possible to obtain stable homozygous lines in a short period of time and to eliminate the lengthy process of inbreeding used in classical breeding to fix the desired traits. Methods. The tissue and cell culture methods for plants was used in the study. Results. The influence of the induction medium composition on the efficiency of in vitro induced androgenesis in varieties and lines of hexaploid triticale is assessed. The influence of three types of induction culture medium, the type of phytohormones and the presence or absence of cefotaxime in the medium are analyzed. Results. It has been shown that using the C-17 culture medium supplemented with 2.0 mg/l 2,4-D and 0.5 mg/l kinetin without adding cefotaxime is most effective for the anther triticale cultivation. Keywords: triticale, anther culture, induction nutrient medium, embryoids, calli, regenerant plants, cefotaxime.
