Pathogenic and genetic characterisation of Fusarium sporotrichioides

Abstract

Pathogenicity of eight F. sporotrichioides isolates, originated from wheat were studied under greenhouse conditions. Based on different parameters of the pathogenicity estimate it was determined that four, two and two F. sporotrichioides isolates expressed none, very low and low degree of pathogenicity, respectively. Three types of nit mutants, nitl (25.6%), NitM (6.9%) and nit3 (0.7%), were obtained by the use of the VCG method. A total of eight VCGs of F. sporotrichioides were established in the complementation tests.
