Variability versus stability of traits and the influence of transposons in ornamental plants using the genus Angelonia as example
Project
Project code: JKI-ZGO-08-4163
Contract period: 01.07.2012
- 31.12.2019
Purpose of research: Basic research
Variability is a precondition for successful breeding and the development of new cultivars. Besides distinctness, uniformity and stability of traits are further obligatory criteria for 'Plant Breeders Rights'. New morphological traits of flower and habit, which are important in ornamental breeding, could result from the function of transposons within plant genomes. Such new traits are only valuable, if the transposons are stable integrated within the genome. The popular genus Angelonia, originated in Latin America, is known in European horticulture since the early nineteenth century and had a remarkable comeback as a 'New Ornamental' about 25 years ago. Angelonia could be used as flowering pot or bucket plant and has a great potential as cut flower. The allogamous Angelonia is propagated by seeds as well as by cuttings. Instabilities of morphological traits suggest the influence of transposons. The project aims at developing suitable Angelonia lines by crossing, self-fertilization and selection, which allows to evidence by molecular methods the transposons and their integration into different positions within the genome. Additionally, the potential of inbreeding and hybridization should be proved.
