Abstract
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.
Highlights
Mustard is grown on 120 hectares of land in Finland
The vegetation reached a height of 112—157 cm by the end of seed ripening
There were no differences between the varieties in sinalbine content
Summary
Mustard is grown on 120 hectares of land in Finland. That equals to a production of approximately 20 % of the self-sufficiency in mustard consumption (Hälvä 1985). Seven varieties of yellow mustard from different origins were cultivated. The eight brown mustard varieties tested were ‘Picra’ (France), ‘Domo’ and ‘Blaze’ (Canada), ‘Trowse’ (England), Sv 8341001 (Sweden) and common varieties in Europe ‘Pusa Bold’, ‘Prakash’ and ‘RLM 198’. In yellow mustard sinalbine e.g. p-hydroxybenzyl glucosinolate, and in black mustard sinigrine e.g. 2-propenyl glucosinolate were determined. The average yield of yellow mustard was 2220 kg/ha in Helsinki and 1860 kg/ha in Kangasala (Fig. 1).
