Summary: Diseases are among the most significant maize production constraints. Grey leaf spot (GLS) disease caused by Cercospora zeae-maydis is recognised as one of the most significant yield-limiting maize diseases worldwide (Ward and Nowell1998; Nutter and Jenco 1992). Recently, it has become the principal maize disease in Ethiopia (Dagne et al. 2001). Most varieties grown by farmers are highly susceptible to GLS. Ethiopia's national maize research project initiated a series of experiments to evaluate and select maize genotypes from local and exotic sources. We identified resistant entries, using artificial inoculation with Cercospora zeae-maydis. Some of the advanced and commercial inbreds with good agronomic performance exhibited highly susceptible reactions to GLS. To date, no studies have been conducted to determine the genetics of resistance to GLS in the lines identified in this program. Thus, this study was undertaken to determine the inheritance of resistance to GLS in the resistant lines identified under Ethiopian conditions.
