Abstract
Waxflower is one of Australia's major native cut flowers for the export market. A number of interspecific hybrid cultivars such as the ‘Pearl’ series bred by the Department of Agriculture and Food, Western Australia have increased the competitiveness of waxflower on world markets. To improve the breeding efficiency, resistance gene analog polymorphisms (RGAP) are investigated as molecular markers for the early identification of interspecific hybrids between Chamelaucium uncinatum and C. megalopetalum. The results show that RGAP can be effectively applied to generate DNA markers to identify true waxflower hybrids. The RGAP marker system provides a reliable, simple, fast and inexpensive approach for hybrid identification in waxflower breeding.
