Traditionally in northwestern Ethiopia, durum wheat landraces have been grown mainly on waterlogged soils (e.g., Vertisols). Due to poor drainage and associated yield limiting factors, the yield potential under these conditions is discouraging (<1 t ha-1). Some farmers are abandoning the crop and its in situ genetic diversity is under threat. Possibilities to stop this trend and increase productivity include improved soil drainage systems. Altenately, selection of durum wheat genotypes productive under well-drained conditions is possible. To identify such varieties, a yield trial was conducted at the Adet Agricultural Research Center in 1996 and 1997. Semi-dwarf and medium-tall durum wheat varieties were tested and all grew vigorously. Significant differences were observed in most traits. Some entries out-yielded all checks, with grain yields of 3.5 t ha-1 achieved.
