Abstract

Different formae speciales of Fusarium oxysporum are the main causal agent of Fusarium wilts. In 2008 and 2009 we collected F. oxysporum samples from symptomless Abutilon theophrasti, Xanthium strumarium, Chenopodium album, Matricaria perforata, Ambrosia artemisiifolia, Polygonum lapathifolium, Sonchus arvensis, Amaranthus blitoides, Amaranthus retroflexus, Datura stramonium, Sorghum halepense and Hibiscus trionum. Only 16 out of 41 isolates of F. oxysporum yielded nit mutants. The frequency of nit3 mutants was higher (43%) than the frequency of nit1 (35%) and NitM (22%) mutants. Two vegetative compatibility groups (VCGs) of F. oxysporum were determined in the complementation tests. These results stress out the problem with isolation of nit mutants and show a high genetic diversity of F. oxysporum isolated from weeds.
