ABSTRACT - Three commercial varieties susceptible to powdery mildew and five high-yielding genotypes with resistance topowdery mildew from the CIMMYT were used in this study to estimate the general combining ability of parents, to detect geneactions of resistance against powdery mildew and identify the most suitable genotype for transferring resistance genes to thecommercial varieties. In conclusion, monogenic inheritance was detected in the F 2 generation in crosses of parent 48 with twocommer cial varieties, Atilla-12 and Basribey . The inheritance of par ent 72 was digenic in cr osses with the same commer cialvarieties. Parent 48 can be recommended as a parent for powdery mildew resistance and improvement of varieties towardshigher spike length, spikelet and kernel numbers per spike and plant height. Parent 72 may also be used for powdery mildewresistance to develop varieties with greater plant height.Key words: wheat, powdery mildew , inheritance, combining ability . 1 Ege University, Faculty of Agriculture, Department of Field Crops, 35100, Izmir, Turkey. *E-mail: emre.ilker@ege.edu.tr
