Patent

CA 2180200

A method for producing plants of the Brassicaceae family that have reduced feeding by cruciferous insects is disclosed. The method comprises selecting for the heritable trait of altered total non-seed glucosinolate levels or for the heritable trait of increased myrosinase activity. Selection may be performed on Brassicaceae cultivars, mutagenized populations or wild populations, including the species Brassica napus, B. campestris and Arabidopsis thaliana. Plants having such altered levels show reduced feeding by cruciferous insects, including flea beetle, diamond back moth and cabbage butterfly. Plants selected for altered levels of both glucosinolates and myrosinase also show reduced feeding by cruciferous insects.
