Analysis of Characters and Germplasm of Significance to Improvement of Australian Native Waratahs (Telopea spp., family Proteaceae) for Cut Flower Production

Abstract

Waratahs (Telopea spp.) are cultivated for their blooms for the international cut flower market. A morphometric study was conducted on a range of cultivated waratah varieties to determine the variability of selected characters of horticultural importance and which parents might be of value in future breeding programs. Univariate analysis of characters of 13 cultivars revealed the greatest range of variation in number of flowers, bract dimensions, flower colour and leaf margin type. Differences were observed between number of flowers per inflorescence in the T. speciosissima (Sm.) R.Br. group of accessions and the other species cultivars; interspecific cultivars with T. mongaensis, Cheel and T. oreades F. Muell. were intermediate, with a similar pattern observed in bract length and width. Multivariate analysis (canonical variate analysis – CVA) discriminated between waratah cultivars on the basis of flower colour (first axis), then flower number, bract length, leaf width and leaf margin type (axis 2). The third axis also separated leaf width, the fourth leaf length and width, and the fifth leaf apex shape, CVA was also used to explore the genetic contribution of three parent T. speciosissima cultivars to hybrid populations. Hybrids with ‘Sunflare’, ‘Sunburst’ or ‘Wirrimbirra White’ as one parent were very dispersed indicating the range of inheritance of the observed phenotypic characters, leading to the possibility of selecting individuals with the required degree of character inheritance. It was demonstrated that the Telopea speciosissima type, which forms the basis of the waratah cut flower industry, may be improved by hybridising with other Telopea species. The application of the results to the development of waratah breeding programs is discussed.
