Abstract

Two species of rape, Brassica campestris L. (turnip rape) and Brassica naplis L. (swede rape), are grown for seed. Turnip rape is mainly grown in Asia, North and South America and Australia, with a little also in Northern Europe. Most of the rape grown for seed in Europe is swede rape. It can be sown either in autumn (winter rape) or spring (spring rape), but recently winter rape cultivars have been favoured because they give heavier yields. Winter swede rape flowers from late April to early June and is harvested in late July; spring swede rape flowers from mid-June to mid July and is harvested in September.
