Information is rare about mustard (Sinapis alba, Brassica nigra, B. juncea) varieties and their characteristics for a suitable performance under organic conditions. 30 accessions were grown at the organic Research Station Kleinhohenheim in SW Germany in the year 2011. Highest grain yield was obtained by S. alba (10.5 g/plant) which was about four times the yield of B. nigra, and ten times the yield of B. juncea, mainly because of higher thousand kernel mass and high number of pods. B nigra and B. juncea were heavily damaged by pests so that only S. alba seems a suitable mustard species for German organic farming at the moment
