Susceptible cv. Yandee and resistant breeding lines CE2:435 and 75A:258 were grown in solution culture at varying levels of Ca supply. Epidermal Ca concentration increased with increased Ca supply in both resistant and susceptible lupins. There was an inverse relationship between the concentration of epidermal Ca and the frequency of infection by the fungus.
