| Summary: | 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 F2 generation in crosses of parent 48 with twocommercial varieties, Atilla-12 and Basribey. The inheritance of parent 72 was digenic in crosses with the same commercialvarieties. 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. |
