Resistance of triticale hybrids with Pm4b and Pm6 genes to powdery mildew
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important foliar diseases of cereals.
Infection by this pathogen on triticale has intensified in Poland in the last few years. In this study we examined
resistance to powdery mildew in triticale hybrids possessing resistance genes Pm4b and Pm6 introduced
from common wheat. The materials tested were hybrids derived from triticale crosses with common wheat cultivars
carrying the desired resistance genes. The presence of the transferred genes was reflected in increased
field resistance and shown by the use of molecular markers. The paper discusses the potential introduction of
the genes to improve powdery mildew resistance
