Six mutants of Penicillium expansum resistant to sodium ortho ‐phenylphenate (SOPP) and four mutants resistant to sodium dehydroacetate (DHAS) were characterized with respect to their levels of resistance, cross‐resistance, virulence, and morphology. The SOPP‐resistant mutants were recessive and the DHAS‐resistant mutants, dominant. The mutants resistant to 50 mg/liter SOPP were avirulent; the mutants resistant to 300 mg/liter DHAS were atypically virulent. Three SOPP‐resistant mutants and two DHAS‐resistant mutants were shown to be nonallelic in each case. By means of the parasexual cycle four linkage groups were proposed to account for the segregants from 14 diploids involving 16 markers.
