Many strains of Verticillium dahliae previously considered vegetatively incompatible based on microsclerotial color mutants were found to be compatible when reassessed using nitrate-nonutilizing (nit) mutants. Sixteen vegetative compatibility groups (VCGs) were found previously when strains of V. dahliae were assayed using microsclerotial color mutants. When 26 strains representing 16 VCGs were reassessed using nit mutants, only four VCGs were identified (...)
