| Abstract:
Proteaceae breeding has a history of about 25 years in South Africa. Within this time span, the need to apply certain basic principles of breeding have become evident. It is possible to divide the genera Protea, Leucospermum and Leucadendron, into well defined marketable products. Within each genus each of the marketable products defines a primary breeding aim. The likelihood of success of developing each of the product lines within the genera is dependent on the ease of hybridization within and between species. Improvement of the products within genera can be divided according to the probability of improvement by intraspecific hybridization. Within product lines, where improvement is limited if using only intraspecific hybridization, interspecific hybridization will have to be used. The latter can result in two types of progeny, namely, improved product line, or unique product unlike any currently on the market. Ultimately the rate of progress within each product line will depend on the ability to overcome inherent problems of low seed set and cross incompatibility between species. | |
