At the beginning of the project a comprehensive characterization of the virulence spectra to Fusarium spp. in the significant growing regions is proposed, to prepare an infection suspension for the biotests, in order that evaluate the plant material adequate to races of Fusarium spp. At the same time, in international genebanks should be searched for wild accessions, to identify suitable resistance to the current virulence spectra, which should be introgressed in highly efficient elite breeding lines. A Phenotyping-protocol should be developed for biotest's in a climate chamber based on the available infection suspension and plant material to get a sure Fusarium spp. infection, which allows a high throughput phenotypisation. Furthermore the offspring’s of segregating populations should be phenotyped regarding to agronomic traits and after finalization of the characterization of the virulence spectra tested and selected for resistance to Fusarium. Selected lines should be advanced up to F9 and tested in field, to identify there the final highly efficient and resistant cultivar candidates. In order to be able to dispense with the costly resistance tests, in the future markers should be developed for the identified resistances. Following this, the acquired infection suspension based of the characterization of the virulence spectra to Fusarium spp., phenotyping protocol and marker developed for wrinkled pea, should be transferred to amylose- and partridge pea. This opens up further breeding perspectives for the effective improvement of these also economically important crops, whereby further sales markets can be opened up in the future.
