Diversity of Rhynchosporium secalis (Oud.) J. J. Davis strains in morphological and cultural peculiarities

Abstract

Biological peculiarities of the rye scald fungus Rhynchosporium secalis (Oud.) J. J. Davis, in one population of North-West region were examined. Seventy-eight isolates, the causal agent of scald, were taken from infected rye plants. This isolates were analalysed on rate of growth on artificial test medium, structure and color and temperature dependence. Single-spore strains were obtained from each natural isolate. Color and structure of some single-spore isolates remained stable through repeated transfers to fresh PDA medium.
