Subject(s): In: Proceedings Borlaug Global Rust Initiative Technical Workshop : Poster Abstracts. Theme 5: Rust Surveillance; Beijing (China); 1-4 Sep. 2012 p. 109Summary: Local landraces, as potential donors of valuable traits such as resistance to rusts, can broaden genetic variability in crop plants. In this study we evaluated Moroccan durum landraces and improved cultivars for stem rust response at Njoro, Kenya, during 2010-11 and for stripe rust response at Annoceur (2009-10) and Meknès (2010-11). One hundred and seventy three landraces collected from different regions of Morocco and 18 improved cultivars were tested at Annoceur during 2009-2010 where were stripe rust and leaf rust were prevalent; 21 and 76 landraces were immune to yellow rust and leaf rust, respectively. A subset of 62 landraces and 18 cultivars were tested at Meknès and Njoro during 2010-2011; 31 landraces exhibited resistance to stem rust (<20MR). Amongst them, 4 accessions were almost immune to stem rust (5R) and two of them were highly resistant to stripe rust. Among the improved durums, stem rust severities ranged from 20MR to 70S, Stripe rust on durum cultivars was not a real threat since the most susceptible one exhibited a severity of 30S.
