Claim:
A method for providing Brassica varieties with elevated levels of anticarcinogenic glucosinolates, comprising: a) crossing a cultivated Brassica oleracea plant with a second Brassica oleracea plant; and b) identifying a progeny Brassica oleracea plant that has at least 100 micromol gluboiberin (3-methylsulphinylpropyl glucosinolate (3MSPG)) per 100 gram of fresh weight of the edible part, wherein the cultivated Brassica oleracea plant is sprouting broccoli ( Brassica oleracea convar. botrytis var. asparagoides ) variety Bordeaux or savoy cabbage ( Brassica oleracea convar. capitata var. sabauda ) variety Wirosa, wherein, in the cultivated Brassica oleracea plant, the anticarcinogenic glucosinolates include at least 3MSPG and glucoraphanin (4-methylsulphinylbutyl glucosinolate (4MSBG)), and wherein, in the cultivated Brassica oleracea plant, the concentration of 3MSPG per 100 gram of fresh weight of the edible part is greater than 280 micromol.
