Description Faba bean (Vicia faba L.) is an important cool season food legurne grown worldwide. Heat is a major abiotic stress that reduces faba bean productivity. Heat stress is increasing in terms of intensity and frequency due to the climatic change and variability. This study aimed to evaluate faba bean accessions
under heat prone conditions. A set of I 76 accessions frorn 2 I countries were tested in alpha lattice design with two replications at ICARDA Terbol, Lebanon during the summer 2015. The maximum air
temperature varied from 32'C to 40.5 oC during the flowering time. The heat tolerance score varied from
2 to 5' Days to flowering, plant height and seeds per plant varied significantly among genotlpes. DFLR
varied from 35 to 120 days. About 36 accessions flowered at 35 days after sowing 1OASI and75 at 45 DAS. Plant height varied from 37 to 79 cm, and Seeds per pod rung.d from 0 to ni9.lin", 1rynn 20 seeds
per plant were considered heat tolerant. Twenty two accessions originating from Egypt, lran, kaq,
Turkey, Sudan, and Spain and TAICARDA improved lines were identified u,
"^t.u "urtyiin", while three accessions originating ffom Sudan and Egypt and 5 improved lines were considered as heat tolerant.
