ABSTRACT

Abiotic stresses are responsible for significant yield losses in durum wheat worldwide. Durum wheat is traditionally grown in the Mediterranean basin, an environment where poor soil, high and low temperature, and drought represent the main limiting factors. Breeding for stress tolerance is an important task to increase durum wheat productivity. Traditional phenotype-based selection has not been completely successful. Stress tolerance is a polygenic trait characterized by low heritability and high “genotype environment” interaction.
