Abstract:
Sandersonia is a mono-specific genus in the family Colchicaceae. In recent years it has become an important flower crop in New Zealand with both cut stems and tubers being exported. Considerable investment has been made in research on agronomy, tuber storage and post-harvest handling of this crop and much of this information has been published. A number of techniques have been employed to produce new forms of Sandersonia. They include inducing and identifying mutants, producing polyploid plants and performing wide crosses using in-ovulo embryo culture. Current work is aimed at characterising various mutants that have appeared. To date two new cultivars have been assigned plant variety rights in New Zealand. These are Santonia cv ‘Golden Lights’ and Sandersonia aurantiaca cv. ‘Phoenix’.
