Effect of variety, different cultivation systems and environmental factors on the metabolite profile of winter wheat grains (AWECOS)
Project
Project code: JKI-ÖPV-08-1372
Contract period: 01.02.2016
- 31.12.2018
Purpose of research: Applied research
To develop sustainable and efficient cereal cropping systems and to assess different breeding strategies 3-years field trials were conducted in winter wheat at five different locations in Germany within the frame of the AWECOS project (SF-1172). Eight winter wheat cultivars with different yield potential and disease resistance are cultivated using three cropping systems with different fungicide application strategies. In addition to ecological and economical analyses of the field trials and the assessment of costs and benefits accruing to society as a whole this working package aims at a comprehensive analysis of metabolites in winter wheat grains obtained from the field trials of the AWECOS project. Using non-targeted metabolite profiling on basis of ultra-high performance liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry (UHPLC/ESI-QTOFMS) the effect of variety, cultivation system and environment on the metabolome of winter wheat grains will be investigated. Because of the general structural diversity of plant metabolites three analytical methods targeting the polar, the semi-polar and the apolar fraction of the wheat grain metabolome will be established and validated. The resulting metabolite profiles will be additionally analyzed in a targeted manner for metabolites known to increase or decrease the nutritional value of wheat grains in order to finally assess grain quality of cultivars in dependence of the applied cropping system.
