The cultivation of strawberries is associated with a high production risk: On the one hand, commercial strawberry varieties are infested by various harmful organisms, on the other hand, strawberry cultivation requires additional irrigation due to the susceptibility of the crop to drought stress.
The use of resistant varieties with improved site adaptation reduces the use of pesticides and conserves water resources. The cultivars which are genetically impoverished due to the funnel effect can benefit greatly from the use of manifold genetic resources of wild species. To this end, the genetic potential of native Fragaria vesca acessions will be evaluated.
It is known that resistance to Colletotrichum acutatum in F. vesca is present. There are also experience reports pointing to the potential of F. vesca for drought tolerance. In the context of the doctorate, resistant genotypes will be identified and developed with mutation breeding methods for variety breeding at octoploid crossing level.

The PhD project is supervised by Prof. Dr. Drewes-Alvarez (HTW Dresden, Faculty Agriculture/Environment/Chemistry) and Prof. Dr. Geilfus (Humboldt-Universität zu Berlin, Department Controlled Environment Horticulture). The project is financially supported by a PhD scholarship of the Deutsche Bundesstiftung Umwelt. The valuable genetics are made available by seeds from the WEL Gene Database.

Gene bank for Pelargonium acessions

In the field of ornamental horticulture, a collection of geraniums will be preserved to serve as a research object and to support teaching. The Pelargonium collection comes from Prof. Dr. Frank Pohlheim (former Humboldt-Universität zu Berlin). Before his emeritus status, he handed over the collection to the HTW Dresden in 2018. Since 01.04.2018, the HTW has been a genus-specific partner of the subnetwork Pelargonium of the gene bank for vegetatively propagated ornamental plants. The collection consists of approximately 50 Pelargonium acessions, including mutations of Pelargonium x hortorum 'Kleiner Liebling'. There is material with different ploidy levels and different flower and leaf forms.

Field of expertise: Fruit growing and tree nursery

Research work, including in the context of final theses:

  • Growing and quality of trees and woody plants via seeds under different conditions (cooperation with the forest tree nursery Graupa)

  • Growing of woody plants via cuttings / cut woods

  • Experiments on the generative propagation of Populus tremula L.

  • Sprouting and shoot growth behaviour of woody plants as a function of the harvest time

  • Increase of drought tolerance of young trees by early adaptation during cultivation (completed PhD project with TU Dresden - possible follow-up work)

  • Investigation of the earthworm population in orchards

  • Resistance tests in the system Fragaria sp. – Verticillium dahliae
