Molecular characterization of genetic potato resources with regard to abiotic stress tolerance or associated traits (association mapping in potatoes) (Project)
Drought stress like other stress factors induces diverse changes in the metabolism of plants. Its impact depends on the time, duration and intensity of the stress phases. Among others, plants respond to drought stress with the accumulation of different substances in the leaves, which may be used as indicators for drought tolerance. At the Institute of Abiotic Stress Tolerance the evaluation of...

Phenotyping of potato genotypes with regard to drought stress (Project)
In Central Europe drought limits the growth and the development of many cultivated plants to an increasing degree. In view of the prognosticated climate changes and the following complex consequences for an economic and at the same time environmentally friendly agriculture the importance of drought tolerance will increase considerably. It is known that also the potato reacts sensitively to water...

Analytical and molecular chararacterization of volatiles in apple fruits (Project)
Plant volatiles are important secondary metabolites of the apple fruit. These chemical compounds produce typical aroma patterns in different apple cultivars and are responsible for the sensorial fruit quality of apple fruits. The trait is known to underlie complex biochemical and genetic interactions and is often negatively influenced in resistance breeding programmes by the apple progenitors...

Genetic and molecular characterization of fungal resistance genes in apple (Project)
Durable disease resistance against apple scab and powdery mildew is one of the main objectives in apple breeding. The knowledge about the existence of mildew races, and the occurrence of new scab races that are able to overcome the Vf resistance widely used in the past in apple breeding have forced the search for new resistance sources as well as the development of efficient molecular breeding...

Resistance Evaluation of Asian Fragaria species to Verticillium-wilt (Project)
One of the most dangerous diseases in strawberry cultivation is caused by the soil-borne pathogen Verticillium dahliae. Susceptibility to Verticillium-wilt occurs throughout the entire modern collection of strawberry cultivars. It is a demand in strawberry breeding to find resistance in the gene pool of the genus Fragaria for later use in breeding programmes. The goal of this project is the...

Evaluation of varieties and plant genetic resources of rye for bioenergy use (Project)
Biomass from rye is a carbon neutral renewable resource that can be produced in large quantities for the conversion into bioenergy. Rye suits both as a winter catch crop followed by maize and as a main crop harvested for total plants silage when the grain is in the milky stage. The focal points of this investigation are to examine the suitability of different rye forms (varieties, tetraploid rye,...

Investigations on the suitability of sorghum for energy recovery (Project)
Use of biomass for energy production is predicted to increase in Germany's agriculture. Especially on light and dry soils, rye offers an alternative to maize for biomass production. Due to their water efficiency, sorghum as well as sorghum x Sudan grass hybrids appear attractive as catch crops in crop rotations with rye as a preceding crop. The present project investigates the agronomic...

Development and evaluation of sweet cherry clones resistant to leaf spot, Blumeriella jaapii (Project)
Cherry leaf spot, caused by fungus Blumeriella jaapii, is one of the most serious fungal diseases of sweet cherry. The objective of the investigations is to evaluate and to describe the resistance of diploid interspecific cross population to leaf spot. In result of these investigations resistant genotypes will be used in breeding and the inheritance of resistance should be studied.

Investigation of nitrogen efficiency in Solanum tuberosum (Project)
The release of nitrogen from fertilizers applied to areas used by agriculture accounts for an increasingly negative impact on ecosystems. Therefore there is increasing demand for cultivars with optimized nitrogen efficiency. Four different components are differentiated in respect to nitrogen utilization of plants: (1) absorption, (2) assimilation, (3) translocation, and (4) remobilization. The...

Development of an in vitro system for characterization of potato genotypes in respect to nitrogen efficiency (Project)
The release of nitrogen from fertilizers applied to areas used by agriculture accounts for an increasingly negative impact on ecosystems. The ability for efficient nutrient uptake and utilisation differs between plant species due to specific morphological and physiological characteristics. Furthermore, genetically based differences have been demonstrated within one species. This indicates the...
