The application of phenoxyacetic acidin rice anther culture in vitro

The regeneration peculiarities of four rice hybrids Oryza sativa L. subspecies japonica in the anther culture in vitro on the nutrient medium containing phenoxyacetic acid 10 mg/lare studied. The callus formation frequency on N 6 and М 8 mediums was equal (4,2% and 4,8%). In the two-step regeneration the albinoproportion after М 8 medium is two times higher than the after Nemedium (p - 0,01). In the one-step regeneration the green plants were not obtained. The possibility of inoculation of the aseptically clean rice anthers without sterilizing agents is shown.
