Polima cytoplasm male sterlity Brassica napus was as maternal plant to cross with Brassica oleracea var. botrytis. The embryo rescue technique was applied to obtain interspecific hybrids. Ovaries of interspecific hybrid with different days after pollination were cultured in different culture media. It is showed that ovaries taken 12 says after pollination appeared most efficient for seed and plantlet production. Altogether 15 seeds were obtained in experiment and eleven of them germinated on MS medium and grew into plants. Of the medium studied, a half MS medium gave the most satisfactory results for ovary culture and the more plantlet were obtained.
