THE CHALLENGES OF BREEDING WILD FLOWER CULTIVARS FOR USE IN COMMERCIAL FLORICULTURE: AFRICAN PROTEACEAE |

| Keywords: | Protea, Leucadendron, Leucospermum, reproduction biology, interspecific hybridization, domestication, ornamental breeding. |
| Abstract:
The three economically important genera of African Proteaceae provide the background to discussing the phases marked by the extent of control over the genetic material. Six phases in the domestication process are outlined: wild harvesting, basic domestication, clonal selection, interspecific hybridization, complete domestication and control of single genes. Each of these phases are discussed, briefly outlining the plant material use, the levels of control over the genetic quality of the material, the supporting research required to fully exploit the opportunities within each phase and the advantages and limitations. | |
