Sažetak
Fusaria of the Liseola section were isolated from 1996 to 1998 corn survey samples (162, 104 and 111 samples respectively) and tested for mating. The incidence of isolates belonging to mating population A (F. verticillioides) ranged from 70.2 percent to 89.5 percent. In the 1996 to 1998 samples, from 63 percent to 91 percent, were contaminated with fumonisins, from 0.1 microg/g to 33.3 microg/g. Pearl millet samples were collected from 1996 to 1998. 119 isolates were paired with mating population A (F. verticillioides), D (F. proliferatum) and F (F. thapsinum) tester strains. No successful crosses were obtained with mating population F, 50.4 percent were fertile with mating population A and 10.1 percent crossed with mating population D. 39.5 percent did not form any perithecia. We isolated Fusarium pseudonygamai from Pearl millet for the first time in the United States, and believe that many of the isolates that were infertile belong to this species. This finding was confirmed by DNA sequence comparisons with known isolates from Nigeria. Fumonisins FB(1) and FB(2) were not detected in any of the 81 analyzed grain samples.
