Sažetak
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.
