Summary A breeding programme is described, aimed at introducing resistance to Phialophora cinerescens in glasshouse carnations of both the standard and the spray type. Four resistant clones, selected from seed-grown garden cultivars, served as resistant parents; the susceptible parents included the major glasshouse cultivar William Sim and some of its mutants and a few other American, French and Italian cultivars. In three generations of breeding, with extensive screening of young seedling populations, an adequate level of resistance had been reached. Selection procedure was henceforth changed to allow for primary selection on quality and productivity, followed by clonal resistance tests. Inheritance of resistance appears to be mainly additive; at least two gene pairs are likely to be involved. Under prolonged high infection pressure a significant non-additive variance can be demonstrated.
