Infection types are based on Brown and Wolfe (1990): 0, fully resistant, no visible symptoms; 1, necrotic flecks, no sporulation; 2, heavy necrotic flecks, scarce sporulation; 3, light necrotic flecks, moderate sporulation; and 4, fully susceptible, no necrosis or chlorosis.
b
R gene designations as in Jørgensen (1994).
c
P and S series of near-isogenic lines derived from Pallas and Siri, respectively (Kølster et al., 1986; Kølster and Stølen, 1987).
