title: Genetic analysis of durable powdery mildew resistance in a common wheat line.
abstract: Genetic studies using monosomic and hybridological analyses had confirmed that resistance of a common wheat line k-15560 to powdery mildew in seedling stage was conditioned by one dominant gene located on chromosome 7B, and resistance in adult stage was controlled by two dominant genes. Cytological analysis of meiosis in the F1 monosomic hybrids has revealed reciprocal translocation involving chromosomes 2A/7A. In the F1 monosomic hybrids genes, causing a decrease in pairing were found on chromosomes 3B and 4D, and genes enhancing pairing--on chromosomes 2A and 3A.
