| Abstract:
The Leucospermum breeding program at the University of Hawaii emphasizes improved horticultural characteristics, such as extended flowering season, vertical plant growth habit with long, straight, and lightweight stems having small leaves. The program also emphasizes genetic resistance to root and foliar diseases. The program relies on the heritability and combining ability of the genes for these desired characteristics from selected species and hybrid stud plants. Seven new hybrids were introduced in 1999 and 19 will be introduced late in 2000, including the first-time release of L. reflexum hybrids. Seven of the new cultivars are in flower by November, while eight extend the late season, normally over in May, into June or July. | |
