Popis: Vegetative compatibility among three isolates of Fusarium oxysporum f. sp. lupini and two isolates of F. oxysporum var. redolens from diseased lupins was investigated. Pairings between five mutants originated from each isolate revealed two compatibility groups. The first VCG comprised race 1 of F. oxysporum f. sp. lupini and one isolate of F. oxysporum var. redolens; the second VCG comprised race 2 of F. oxysporum f. sp. lupini and two isolates of F. oxysporum var. redolens. Heterokaryon formation was observed in many pairings involving mutants of both taxa. These findings provide evidence of the conspecificity of these two taxa and they support Gordon's classification (1952) according to which F. redolens is actually F. oxysporum.
