| Abstract:
Fusarium resistance has recently been introduced as a major selection criterion in a long-term breeding programme originally intended to incorporate resistance to Phialophora in glass-house carnations. The decision to alter the priorities in this current programme, rather than starting a separate programme for Fusarium resistance, was based on the results of several preliminary investigations. These showed that most conditions for success in Fusarium resistance breeding were met: (a) A reliable screening technique; (b) a wide variation in Fusarium resistance in the available breeding material; (c) levels of resistance, adequate to provide protection under commercial conditions in both standard large-flowered and spray clones and, finally (d) resistance readily transmitted from parents to progenies. The high proportion of the available breeding material that is resistant to Fusarium is explained by a partly common genetic basis for Phialophora and Fusarium resistance. | |
