Abstract: Three Bulgarian rice varieties were study regarding some sowing qualities and phytosanitary status of the seeds. The experiment was conducted in two variants – control and treatment with 3.0% hydrogen peroxide (Н2О2). Variety Mizia was with the best sowing qualities among the studied varieties. A presence of fungi from genus Fusarium, Alternaria, Penicillium was established as a result of the phytopathological analyses. In strongly infestation of the seeds, the treatment with hydrogen peroxide gives a positive effect on the germination, while in seeds with smaller infestation this treatment has no significant effect on their germination.
