Collaborative project: Marker assisted selection for the improvement of plant architecture and inflorescence size in chrysanthemum – Subproject 1
Project
Project code: 2814304007
Contract period: 01.06.2010
- 31.05.2013
Budget: 110,147 Euro
Purpose of research: Experimental development
The aims of this project were the development of molecular markers for complex ornamental traits (flower shape and size and shoot branching) and the optimization of the seed set in the chrysanthemum. Therefore, the phenotypic and genetic diversity was analysed in a collection of chrysanthemum cultivars. These results were used to establish three biparental populations, that were derived from crossings of paternal plants differing in the investigated traits. Data on these traits were obtained for these populations and a bulked segregant analysis for the flower size and the shoot branching was conducted. A total of 30.000 were screened and marker-trait associations were identified for both of the traits. However, these marker had only small effects on the found phenotypic variation. Thus, their use is costly and not applicable for marker assisted selection, yet. Currently, phenotypic selection should be preferred for the development of new chrysanthemum varieties.
