Yield and glucosinolates in mustard seeds and volatile oils in caraway seeds and coriander fruit. I: Yield and glucosinolate contents of mustard (Sinapis sp., Brassica sp.) seeds

Different varieties of yellow mustard (Sinapis alba L.), brown mustard (Brassica juncea (L.) Czern.) and black mustard (Brassica nigra (L.) W.D.J. Koch) were tested in 1983—1985 at three locations in Finland. The average seed yield of yellow mustard was 2220 kg/ha, it’s sinalbine content being 2.2—5.2 g/100g. There were no major differences between the tested varieties. Varieties ‘Kirby’ and ‘Gisilba’ produced the largest yields. ‘Gisilba’ and ‘Ochre’ had the shortest growth periods. The sinalbine content in yellow mustard seeds varied more between the years than between the varieties. The average yield of brown mustard was 1620 kg/ha. The variety ‘Picra’ was slightly better than the other varieties with respect to yield and early ripening. The sinigrine content in brown mustard seeds were approximately from traces to 4.4 g/100 g those of ‘Dome’, ‘Blaze’, ‘Sv 8341001’ and ‘Trowse’ being highest. Black mustard yielded less than 700 kg/ha, the sinigrine content of the seeds being 1.8—4.5 g/100g.
