The aim is to develop high-performance and yield-stable pea varieties using the speed-breeding approach, which allows a higher selection intensity per year and thus significantly accelerates breeding progress. Yield security should be significantly improved by resistance to Fusarium spp. For this purpose, a comprehensive characterization of the virulence spectrum of Fusarium spp. in the important cultivation areas is planned at the beginning of the project in order to be able to prepare inoculation solutions for resistance tests and to test plant material for races of Fusarium spp. as required. At the same time, wild accessions will be searched for in international gene banks to identify suitable resistances for the current virulence spectrum, which will be transferred into high-performance elite material. For the resistance test in the climate chamber, a phenotyping protocol is to be developed using already available inoculation solutions and plant material for a Fusarium spp. infestation, which allows efficient high-throughput phenotyping. Furthermore, the progeny of splitting populations will be phenotyped with respect to agronomic traits and, after the characterization of the virulence spectrum of Fusarium spp. has been completed, will be tested and selected for Fusarium resistance. Selected lines will finally be further developed up to F9 and tested in the field in the last year of the project in order to be able to identify final high-performing and resistant variety candidates there. In order to be able to do without the timeconsuming resistance tests in the future, markers for the identified resistances are to be developed. Subsequently, the results obtained with marker peas will be transferred to fodder and amylose peas. This will open up further breeding perspectives for the effective improvement of these crops, which are also economically important, and open up sales markets.
