Abstract
Doubled haploid (DH) technology has become a powerful tool for basic and applied plant research. The main and routine use of DH technology is the production of pure lines in the breeding process to obtain hybrids. The success of such biotechnological approaches lies in the high level of efficiency of in vitro plant cell and tissue culture protocols . The processes of induction of embryogenesis and regeneration of plants from embryoids are fundamental for in vitro culture technology of isolated microspores. As a result, we have studied and modified the main factors affecting these processes to increase the embryoid yield in the studied genotypes of plants of the genus Brassica.
