Unravelling novel genetic variation by studying the interactions between wheat and rust diseases for a pesticide-reduced wheat production
The five interactive scientific work packages examine the existing resistance of 200 wheat lines from genetic resources and 50 elite wheat cultivars at a total of nine locations, including Australia. Natural and artificial inoculation will be done...
Term: 2022-10-01 bis 2025-09-30Floristic biodiversity in organic farming
The JKI carries out various investigations into organic farming on a long-term test area south of Braunschweig. Since the beginning in 1995, the weed flora has been recorded and evaluated at irregular intervals. To describe the biodiversity, the...
Term: 1996-03-01 bis 2026-12-31Development of digital forecasting models and decision support systems in plant protection for the assessment of infestations of insect pests in oil seed rape, sugar beet and maize
As part of the “EntoProg” project, JKI-A is investigating the population-ecological fundamentals of harmful organisms required to create the forecast and decision-making models. Oilseed rape: Existing damage thresholds are checked for the...
Term: 2021-11-01 bis 2026-10-31Trap cropping to control insect pests in oilseed rape
Treatment index of insectidides in oilseed rape in 2011 to 2017 was 2,75. Nevertheless yield and cropping area in Germany is decreasing. Beside some physiological symptoms and low precipitation insect pests are an important factor. Insecticide...
Term: 2021-07-01 bis 2024-12-31Determination of the resistance of potato genotypes to the potato cyst nematode Globodera pallida
The potato genotypes are tested for resistance in growthchamber and greenhouse experiments. For this purpose, experiments with tissue culture plants are carried out under semi-sterile conditions. Furthermore, the same genotypes are made available as...
Term: 2022-01-01 bis 2024-12-31Development and testing of practicable procedures for inactivation and detection of potato wart disease causing fungus Synchytrium endobioticum in solid and liquid soil) residues (SYNergie)
- Microscopic analyzes winter sporangia (Synchytrium endobioticum) to identify their vitality - Conducting of bioassays to determine vitality of winter sporangia - Methodical development of infection experiments on meristem cultures - Creation...
Term: 2021-06-15 bis 2024-08-14Genetic analysis and modeling of the wheat-rust interaction to develop stable, multi-resistant wheat varieties
The aim of RustHealth is, on the one hand, a deeper understanding of the plant-pathogen interactions for yellow rust and brown rust in wheat enabling to use resistances sustainably for stable wheat production with reduced crop protection...
Term: 2023-09-01 bis 2028-08-31RNAi-based epigenetic disease resistance in wheat
While epigenetic processes are well-known to regulate different aspects in plant development, their importance for plant disease protection has just started to be recognised. Plant pathogens release small RNAs (sRNAs) to manipulate mRNAs and gene...
Term: 2022-07-01 bis 2025-06-30Development of sustainable control strategies against virus yellows in sugar beet based on RNA-spray
To achieve the project goals, in a first step essential RNAi target genes in M. persicae and yellowing viruses have to be identified In the following, appropriate pathogen-specific dsRNA molecules are designed, the RNA interference induction in the...
Term: 2021-10-01 bis 2024-09-30Securing the supply of raw materials by establishing permanent potato wart resistance
The main goal of this project is the identification of new resistance mechanisms against S. endobioticum as well as pyramiding different resistance mechanisms to provide stable resistance against higher S. endobioticum pathotypes. An in vitro...
