Abstract:Summary Leaf and root tissues of clubroot-resistant cabbage line 8–41 and cultivar Badger Shipper, and clubroot-susceptible cultivars Penn State Ballhead and Golden Acre were analysed for free amino acid content. There was no relationship between total free amino acid content and susceptibility to the disease. Alanine and asparagine contents were higher in the leaf tissue in resistant cabbage. Tyrosine content appeared to be higher in the root tissue of the resistant plants than that of susceptible ones.
