Investigation and a new evaluation method of the resistance of amize hybrids grown in hungary to Fusarium moulds.

Thirty maize hybrids grown in Hungary representing groups FAO 200 – 299, FAO 400 – 499 and FAO 500 were inoculated using the toothpick method with Fusarium graminearum and F.culmorum. After nine weeks, large differences among hybrids were observed for the mould covered area of the ear surface ( 2 – 39%), ZEA content (4.2 – 71.2 mg/kg) and T-2 toxin content (1.6-122.5 mg/kg). Relatively poor correlation was found between the area of mould covering the ear surface and mycotoxin content of maize. Although a decreasing tendency in resistance of hybrids with a longer growing vegetation period could be observed, resistant genotypes were found in every FAO group, confirming the views that in addition to the influence of duration of the vegetable period on the resistance, genetic factors may also play a significant role.
