Italics depict significant effects. Seeds originated from three populations (pop effect), WIN, KIM and OH, in Dorset, England. GSLs were classified as aliphatic with variable change length (C3 or C4) or indolic. For the full names of the GSL compounds, see Fig. 1 and the “Glucosinolate analysis” section
