Abstract
Fusarium head blight (FHB), also called ear blight or scab is
economically one of the most serious fungal diseases of wheat in many
producing regions of the world. It is a serious threat for the quality of wheat
products. Also the production of mycotoxins can be harmful to human and
animal health. The aim of this study was to determine the effect of heading
date on grain yield due to Fusarium infection that could result in favourable
conditions of infection. The earliest heading date had genotype Srpanjka, and
the latest Osk.870/08. Grain yield in the treatment with artificial inoculation
and fungicide protection varied from 71.9 dt ha-1 (Olimpija) to 104.4 dt ha-1
(Vulkan), and in the treatment with natural conditions from 74.7 dt ha-1
(Divana) to 112.6 dt ha-1 (Osk.116/09). The highest AUDPC for the total
resistance had genotype Osk.110/09 and the lowest Divana. We conclude
that Fusarium infection is dependent on the heading date, depending on
weather conditions that could potentially cause strong or weak intensity of
infection between heading and flowering days. This research has not found
an association between relative grain yield and heading date.
