Cabbage, kale, turnip, mustard, broccoli, cauliflower and pak choy are among the most widely cultivated vegetables in the world.

They all belong to a family known as Brassica crops.

There are around 40 species in the Brassica genus, but only six varieties are cultivated on a large scale worldwide.

Given the wide variety of forms, Brassica species have many uses. Some varieties are grown as vegetables, fodder crops or for use in cosmetics and medicine. Rapeseed is the second most used source for producing vegetable oil for food and biofuel.

But the diversity of Brassica plants and their wild relatives is in decline.

A global crop conservation strategy developed by the Crop Trust and our partners ensures that the widest variety of Brassica is safely conserved so that future generations can enjoy them forever.
