| Abstract: | Field strains of Fusarium nygamai (Gibberella nygamai) are important producers of the fumonisin mycotoxins. Such strains were mated on carrot agar to obtain ascospore progeny. Field strains and ascospore progeny of F. nygamai produced differential levels of fumonisin B1 (FB1) and B2 (FB2) suitable for genetic analyses. Most of the strains produced higher levels of FB1 than FB2. Ascospore progeny from crosses segregated in 1:1 ratios for loci controlling FB1 production and mating type. These findings can be used as the basis to elucidate the genetics of fumonisin production by F. nygamai. |
