<p>Durum wheat is a crucial crop in the Mediterranean Rim, deeply rooted in the region’s history and traditions. Unlike bread wheat, which shows partial resistance to Fusarium foot and root rot (FFRR), an important soil borne disease, many modern durum wheat varieties remain susceptible, highlighting the need for reliable resistance sources. This study screened 100 Tunisian durum wheat landraces for resistance to FFRR at both maturity over two successive years (2021 and 2022) and seedling stages, comparing them against modern durum wheat cultivars and a resistant bread wheat check. Results indicated that 55% of accessions exhibited resistance in 2021, with this percentage increasing to 80% in 2022. The stability of resistance classifications across years emphasizes the robustness of certain landraces, which performed better under stressful conditions compared to modern cultivars. Notably, the research found no strong correlation between disease severity at seedling and mature stages, suggesting that seedling-stage screenings cannot effectively replace adult-stage evaluations. Additionally, while whitehead incidence is correlated with disease severity, the present study demonstrated that its reliability as an indicator can be considered under high disease pressure. The study further explored the relationship between heading date, plant height, and resistance, finding no consistent correlation and suggesting a need for further research into traits like root architecture that may influence both drought tolerance and FFRR resistance. Overall, these findings enhance our understanding of the genetic potential of durum wheat landraces and highlight the importance of exploring diverse genetic resources to improve the resilience of this vital crop.</p>
