The responses of 92 barley genotypes to selected Puccinia hordei pathotypes were assessed in greenhouse tests at seedling growth stages and in the field at adult plant growth stages to identify known and/or unknown resistances. On the basis of multipathotype tests, 35 genotypes were postulated to carry Rph1, Rph2, Rph4, Rph5, Rph12, RphCantala, alone or in combination (Rph2 + Rph4 and Rph1 + Rph2), whereas 52 genotypes lacked seedling resistance to P. hordei to the pathotypes used. Five genotypes carried seedling resistance that was effective to all pathotypes, of which four were believed to carry uncharacterised resistance based on pedigree information. Field tests at adult plant growth stages indicated that while 28 genotypes were susceptible, 57 carried uncharacterised APR to P. hordei. Pedigree analysis indicated that APR in the test genotypes could have been derived from three different sources. The resistant responses of seven cultivars at adult plant growth stages were believed to be due to the presence of seedling resistance effective against the field pathotypes.
