Breeding durum wheat for biotic stresses in the Mediterranean region
Durum wheat has evolved into a cereal speciality crop with numerous end uses characteristic to the Mediterranean region. In this region however, numerous biotic and abiotic stresses limit the profitability from this crop. Different fungal and viral diseases as well as insects and aphid pests are causing losses in yield and quality of durum wheat crops in the Mediterranean countries. Breeding for resistance or tolerance to biotic stresses has helped in the past and will permit to improve and stabilise yield without heavy use of chemicals. This paper is a review of breeding efforts of southern Mediterranean region NARs in concert with the CIMMYT-ICARDA program as supported by the West Asia And North Africa Dryland Durum Improvement Network (WANADDIN) IFAD project. Results of research on breeding for resistance to leaf rust, yellow rust, septoria, root rot, powdery mildew, hessian fly, smuts and bunts, saw fly and barley yellow dwarf virus are evaluated.
