Ministero dell'Istruzione, dell'Università e della Ricerca Comisión Interministerial de Ciencia y Tecnología, CICYT (España) Durum wheat Leaf rust Resistance gene Marker-assisted selection Marone, Daniela et al. The Italian durum wheat cultivar Creso possesses a high level of durable resistance to leaf rust based on both hypersensitive and non-hypersensitive components. In order to investigate the genetic basis of this resistance, a segregating population composed of 123 recombinant inbred lines (RILs) derived from the cross Creso × Pedroso, was evaluated for disease severity in adult plants under field conditions. Furthermore, the resistance of parents and RILs was evaluated by assessing macroscopically the latency period and microscopically the number and type of pathogen colonies formed following artificial inoculation with a specific isolate. This experiment was performed at controlled conditions at two developmental stages. Besides some minor QTLs, one major QTL explaining both reduction of disease severity in the field and increased latency period was found on the long arm of chromosome 7B, and closely associated PCR-based and DArT markers were identified. This work was supported by Ministero dell’Università e della Ricerca (MiUR) of Italy special grant AGROGEN, by Spanish Comisión Interministerial de Ciencia y Tecnología (CICYT) grant PET2007-0492, and by COST860–SUSVAR.
