Durum wheat (Triticum durum Desf ) is one of the most important cereal crops in Algeria. During the agricultural season 2021-2022, typical symptoms of Fusarium Head Blight were observed in wheat fields in the Setif region. One of the causal agents was identified on the basis of morphological characters and DNA sequences as Fusarium clavum J.W. Xia, L. Lombard, Sand.-Den., X.G. Zhang & Crous, a member of the Fusarium incarnatum-equiseti species complex. It was isolated from symptomatic wheat glumes. In vitro and in vivo pathogenicity tests were conducted on three Algerian durum wheat varieties to assess the effect of this isolate on the seedling and the mass of durum wheat kernels. The results showed that Fusarium clavum caused a significant reduction in the coleoptile (38.9 %) and root length (42 %) and decreased kernels mass by 20.8 %. This study further confirms the presence of Fusarium clavum as an agent causing Fusarium Head Blight on wheat in Algeria.

• Title: Ocena patogenosti glive Fusarium clavum, kot povzročiteljice pšeničnega ožiga v Alžiriji

Abstract

Trda pšenica (Triticum durum Desf ) je eno izmed najpomembnejših žit v Alžiriji. V pridelovalnih sezonah 2021-2022 so bili na pšeničnih poljih na območju Setifa opaženi značilni simptomi pšeničnega ožiga, ki ga povzroča gliva iz rodu Fusarium. Kot povzročitelj je bila na osnovi morfoloških znakov in DNK zaporedij prepoznana gliva Fusarium clavum J.W. Xia, L. Lombard, Sand.-Den., X.G. Zhang & Crous, predstavnica iz kompleksa vrst Fusarium incarnatum-equiseti. Izolirana je bila iz simptomatičnih pčeničnih plev. In vitro in in vivo testi patogenosti so bili narejeni na treh alžirskih sortah trde pšenice za oceno učinka tega izolata na sejanke in maso pšeničnih zrn. Rezultati so pokazali, da je gliva Fusarium clavum povzročila značilno zmanjšanje dolžine koleoptile (38,9 %) in dolžine korenin (42 %) ter zmanjšala maso zrn za 20,8 %. Raziskava potrjuje prisotnost glive Fusarium clavum kot fuzarijskega povzročitelja pšeničnega ožiga v Alžiriji.
