Nutzung pflanzengenetischer Ressourcen für den ökologischen Landbau am Beispiel von Wintererbsen

Summary

Winter peas were cultivated in Germany in the first half of the 20th century for green manure, green forage or as a threshing crop. So far they are mainly used in field ex-periments, e.g. at the University of Kassel. But winter peas are very interesting for or-ganic farming, because of their high N-fixation rate and their ability to suppress weeds effectively. In the vegetation period 2002/2003 twelve genotypes of winter peas from the German genebank in Gatersleben were examined in field trials. In the long and cold winter of 2002/2003 eight different genotypes from Germany, Hungary and the Balkan survived. The yield of the eight accessions as green forage and as a threshing crop (yield between 3 – 4 t/ha) are promising.
