摘要

Although leucadendrons are traditionally marketed as greens/foliage-type flowers, a high market demand potentially exists for superior quality Leucadendron single stem cut flowers as a separate product. A problem with Leucadendron is that the desirable cut flower combination of attractive large flower heads, long flowering branches and high yield is almost impossible to find within a single species. Therefore, interspecific crosses must be used to combine good qualities from different species. A three-phase programme was launched to breed such leucadendrons: (1) testing for cross compatibility amongst species; (2) an interspecific hybridization programme; and (3) selection and evaluation of the programme. The test study showed that Leucadendron species hybridize comparatively well within the subgenus Alatosperma. In the hybridization programme, vigorous, high yielding, F1 hybrids with exceptionally long stems and attractive, large flower heads were found. In addition, these selections have a relatively wide seasonal flowering/marketable period.
