Interspecific and intergeneric hybridization

This project aims to increase present understanding on reproduction biology aiming in development, application and evaluation of methods to overcome interspecific and intergeneric fertilization barriers. The gained knowledge will make it possible to combine traits from different gene pools, providing the breeder the possibility to develop novel plant species and to add a new type of characteristics to current cultivars e.g. increased disease resistance, improved quality or cold tolerance. 

Several techniques can be developed to overcome problems after fertilization and during seed set. If the barrier inhibiting successful embryo development lies after fertilization, in vitro embryo rescue techniques are applied, e.g. ovule culture. Presently, the project comprises studies on pre- and postfertilization barriers in several ornamental plant species comprising Hibiscus, Kalanchoe, Campanula and Hydrangea.
