Title : New locus of barley resistance gene to powdery mildew

Abstract:

Blumeria graminis f. sp. hordei is one of the most ecomicaly important pathogen of barley. This windborne fungus causes powdery mildew foliar disease and yield looses due this pathogen may rich up to 20-30%. In addition to yield losses it is observed lowering of grain quality, particularly disadvantageous for malting barley. Resistence for powdery mildew is the aim of numerous breeding programmes. Searching for new resistance genes can be based on barley landraces.  

Barley landrace Bgh255-3-3 resistant to broad spectrum powdery mildew isolates was investigated. Analyses of mapping population with microsatellite markers lead to define new resistance locus on 2H barley chromosome. Genetic association map of 2H chromosome with resistance gene origin from Bgh255-3-3 was obtained.

Broadening available barley gene pool has practical application. Introducing and pyramiding new resistance genes to new cultivars reduce impact of disease on yield.

This work was supported by programme: “Creation of scientific basis for biological improvement and plant genetic resources protection as source of innovation and support of sustainable agriculture and national food security” funded by Ministry of Agriculture and Rural Development (Poland). Project No. 3-2-00-0-02 (WP 2.2): “Broadening of barley gene pool.”
