Chromosomal Location of Pm12-A Novel Powdery Mildew Resistance Gene from Avena sterilis.

ABSTRACT: Identification of new, effective disease resistance genes is a very important aspect of plant breeding. Also important is the precise location of individual loci and tagging them with DNA markers for marker assisted selection. The aim of the present study was identification of the molecular markers linked with Pm12, a new effective resistance gene to powdery mildew, and their location in the oat genome. The analysis was performed on 167 F₂ individuals from a hybrid of Fuchs × CN67383, with the status of the locus in each individual verified by progeny test in F₃. Segregation ratios confirmed the monogenic nature of resistance. Making use of the sequence data of DNA markers and the oat OT3098 v2 genome reference assembly, Pm12 is located on chromosome 7C.
