ABSTRACT = {Fusarium head blight (FHB) is a disease caused by several <i>Fusarium</i> species, notably, <i>F. culmorum</i> and <i>F. graminearum</i>. These pathogens adversely affect the technological and sanitary qualities of cereal grains, particularly durum wheat. Under favorable environmental conditions and in susceptible varieties, these <i>Fusarium</i> species can significantly reduce both the quantity and quality of crops. This study evaluated the pathogenicity of the two <i>Fusarium</i> species (FC2006 and FG2008) in the growth of durum wheat coleoptiles. The plant material included four commercially grown parental varieties (G9, G10, G11, G12) and eight breeding lines (G1, G2, G3, G4, G5, G6, G7, G8). <i>In vitro</i> tests revealed that both <i>Fusarium</i> species significantly reduced the coleoptile growth across the studied varieties and lines (<i>p</i> ≤ 0.001). The control test had an average coleoptile length of 37.87 mm. In contrast, seeds inoculated with FC2006 had an average length of 0.62 mm, and those inoculated with FG2008 had only 0.064 mm. Although there was a slight difference in aggressiveness between the two species, it was not statistically significant (<i>p</i> > 0.05). Some variability was also noted in the responses of the durum wheat varieties and lines. The G8 genotype showed remarkable behavior in both isolates, with an average length of 1.83 mm for FC2006 and 0.4 mm for FG2008. The other genotypes showed total inhibition of coleoptile growth (0 mm). These findings highlight the importance of conducting further research on the defense mechanisms of durum wheat against <i>Fusarium</i> and assessing the local varieties’ pathogenicity to better explore the interactions between these pathogens and durum wheat genotypes under <i>in vitro</i> conditions.},
