These and other isolates of FOL were characterized for pathogenicity, race and vegetative compatibility group (VCG). Of the 39 California isolates, 22 were in VCG 0030, 11 in VCG 0031 and six in a newly described VCG 0035. Among isolates of VCG 0030, 13 were race 3 and nine were race 2. Of the isolates in VCG 0031 seven were race 2, one was race 1, and three were non-pathogenic to tomato. All six members of VCG 0035 were race 2. Restriction fragment length polymorphisms (RFLPs) and sequencing of the intergenic spacer (IGS) region of rDNA identified five IGS/RFLP haplotypes among 60 isolates of F. oxysporum from tomato that coincided with VCGs. Based on RFLP haplotypes of genomic DNA, five race 3 isolates from California shared the same haplotype with a race 2 isolate from the same location, and all 13 race 3 isolates clustered together into a subgroup in the neighbor joining tree. Collective evidence suggests that race 3 in California originated from the local race 2 population.} }
