A biparental Vicia faba mapping population was screened under glasshouse conditions for resistance to a mixture of Fusarium avenaceum and Fusarium oxysporum, revealing several families with moderate to high resistance. Using the Vfaba_v2 Axiom SNP array, a high-density linkage map of 6,755 SNPs was constructed, enabling the identification of a major QTL on linkage group 4 associated with partial resistance to foot and root rot.

The study demonstrates that the GIGANTEA (GI) protein is a core component of the wheat circadian clock, required for robust oscillations in chlorophyll fluorescence and clock gene expression. Loss of functional GI leads to delayed heading under both long and short photoperiods, indicating a photoperiod‑1‑dependent pathway distinct from Arabidopsis. These findings provide insight into photoperiodic regulation of flowering in wheat, informing breeding strategies for high‑yield cultivars.
