Bestimmung der genetischen Variabilität und Auswahl interessanter Genotypen einer wirtschaftlich bedeutenden Wildobstart, der Kornelkirsche
Abstract
Since C. mas is a long-lived species with a long generation cycle (> 10 years), breeding efforts are very time-consuming. That is why the right choice of parents is crucial. Decisions about the choice of parent individuals must be underpinned by modern molecular technologies and directed directly at the genes that are of interest to the features. Techniques such as ISSRs and Eco-Tilling will be used to identify the individuals with the best properties from the perspective of human health. In the Pielach Valley, the first selections were first cataloged according to morphological characteristics and selected as potential candidate parents for breeding. Since this region is extended to the neighboring Traisental, where cornelian cherries have been cultivated for a long time, additional mapping of plants (using GPS / GIS) is required. A future sustainable production of cornelian cherries requires a gene pool adapted to the local conditions, which could change under changing environmental and climatic conditions. For example, the pressure from disease pathogens (pathogen pressure) could rise. The main objective of the project is to assess the available genetic diversity of the cornelian cherries and to develop breeding strategies for the following specific questions on health aspects. The specific objectives are: • Assessment of the genetic variation according to morphological parameters of the cornelian cherry • Planting a collection of cornelian cherries (Cornetum) from different regions of their distribution area • Establishment of an in-vitro collection of C. mas from different regions • Establishment of a defined methodology (molecular toolset) to identify interesting parent lines for future breeding programs using ISSR and ECO-Tilling • Characterization of C. mas sources with regard to health-relevant ingredients; Development of metabolic profiles of selected genotypes and determination of antioxidative capacity • Clarify whether there is a link between fruit color and health-related ingredients • Identification and selection of the most valuable genotypes for future breeding This project proposal therefore has the following long-term objectives: a) to ensure and expand the future production of cornelian cherries in the Dirndl Valley b) to strengthen the profitability of farms by expanding the product range c) to make the most of the health-relevant ingredients.
