Abstract

Barley yellow dwarf virus (BYDV) is the most important virus affecting grain crops. Over 40% of barley grown in Tunisia may be contaminated in some regions. Selection of resistant genotypes is the best way to fight BYDV. Ten F2 barley populations with some parents carrying the resistance gene Yd2 provided by ICARDA have been the subject of a breeding program. In total 198 F2 to F5 advanced lines were selected for their resistance. The lines’ resistance was evaluated at the symptomatic, serological, and molecular levels with the Ylp (CAPS) marker linked to the target gene (Yd2). The lines’ agronomic performance was evaluated during the 2006–2007 crop year in Béja (a subhumid region) and Kef (a semi-dry region). Twenty-five lines were selected for their grain yield and all were superior to the susceptible cultivar “Rihane”, but only eight lines did better than the susceptible cultivar “Manel”. Sixteen of those lines could be grown for both grain and straw production, and two lines present adaptation capability to semi-dry and subhumid growing conditions. [Journal translation].<br/>
