  • a Individual RPP1-Ws genes are sufficient to provide resistance to the H. parasitica isolates shown (Botella et al., 1998). NT, not tested.

  • b RPP1 locus resistance specified by a single gene, RPP1-Nd (Gordon, 2002).

  • c Noks1 was derived from an oospore of Noco2 (used in Botella et al., 1998), and its interaction phenotype matches that of Noco2 (Holub et al., 1994).
