Abstract
Genera from the Hyacinthaceae family have been utilized in breeding programs at the Agricultural Research Council for many years with the aim to develop new products for the international floriculture market.
Through conventional breeding, several Lachenalia and Ornithogalum cultivars were released.
The Lachenalia breeding program was the only active breeding program during the past 5 years and several potential new lines (comprising of different colour combinations and flower forms) are available for commercial evaluation.
Besides conventional breeding, a project on the use of mutation technology has also resulted in the availability of new lines.
Members of the Hyacinthaceae are particularly suitable for mutation breeding because two of the positive circumstances for mutation breeding can be combined: vegetative propagation and single cell origin of adventitious buds on leaf tissue.
A method combining irradiation and tissue culture was developed to induce mutations in four genera, namely Lachenalia, Ornithogalum, Eucomis and Veltheimia. To date at least four potential new varieties have been identified from three of the four genera.
These lines have been initiated in tissue culture for multiplication purposes.
When large quantities of material are available, application for Plant Breeders Rights and commercial establishment will take place.
