Development of new, broad Fusarium resistances in wheat to meet the specific challenges of current bio-energy crop rotations
Project
Project code: JKI-A-08-1191
Contract period: 01.01.2013
- 30.06.2016
Purpose of research: Applied research
An important aim of the EU Directive 2009/28/EG ('Erneuerbare-Energien') is the marked increase of bioethanol as a petrol substitute by local plant production until 2020. For a balanced bio-energy crop rotation wheat is an interesting crop, because in addition to the bioethanol production the stillage is an important by-product that is used as high-protein animal feed. In addition to the loss of yield reduces the infestation of Fusarium-fermentable starch, and thus the ethanol yield / ha. Wheat is also interesting due to its dual purpose, for the production of ethanol stillage is as high quality animal feed. The heat-stable toxins from contaminated wheat, however, remain in the slurry and prevent their optimal use. Therefore, and due to the expanded range of fungi infestation (flower and root infection) a development of better protected wheat plants is urgently needed. This project is to link the genomic selection with in-depth diagnostic phenotyping of systemic disease development in a comprehensive and diverse range of wheat. This range of globally significant Fusarium hotspot regions is unique and can expect a rich, new resistance spectrum. This should be analyzed for efficient resistance against both main ways of infection, flower and root. End of the project is to develop new resistance, and wheat strains for bioethanol production, breeding and science to be available. As part of the subproject by JKI Braunschweig the phenotyping of the 460 wheat genotypes with artificial incoluation will be carried out. For this, the JKI will provide the Fusarium isolates, infectious materials and test methods for artificial infection for all poreject sites and analyze the toxin contamination in harvested grains. In the years 2012 to 2015 the resistance of the genotypes will be assessed and toxin analyzes (Deoxynivalenol, Zearalenon, T2/HT-2-Toxin) of selected samples from all harvest field locations should be conducted.
