Rye

Characterization of resistance donors against soil-borne cereal mosaic virus (SBCMV) and wheat spindle streak mosaic virus (WSSMV) in genetic ressources of rye and their use for breeding of virus resistant cultivars

Project description:

The aim of the project is to characterize pre-evaluated resistance donors against soil-born viruses in rye and to identify new donors for the development of elite breeding material. In 2008-2011 virus resistance will be analysed in segregating rye populations. After evaluation of new resistance donors, new segregating populations will be developed and crosses for allelism test will be made. The plant material will be evaluated in the growth chamber and in the field. The influence of different pathogen populations will be examined and the inheritance of virus resistance in the progenies will be studied. Through combined analysis of phenotypic and molecular marker data, genomic regions influencing virus resistance will be identified and molecular markers for the selection of resistant genotypes will be provided. The plant material and molecular markers developed in the project will be used in practical plant breeding. New insights in virus resistance in rye will be gained.
