Actions and means involved

Working Collection

A working collection of 600 accessions of Avena genetic resources of different improvement status will be established. It will consist of wild species accessions, land races selected on the basis of the results of a preceding action, and modern cultivars. Multiplied seed of the working collection will be used in field experiments for quality, with artificial Fusarium inoculation and for the observation of cold tolerance.

 

Field experiments

Field experiemts targeted to the observation of quality traits will be set up in Sweden, Estonia, Poland, France, South Italy, Romania and Bulgaria on sites suited for the production of high quality oats. Observations on a limited set of descriptors with relevance to the build up of groat quality will be taken in the field. Criteria for technical quality (seed weight, test weight, hull content) will be observed on harvested material.

 

Fusarium and Mycotoxins

Field experiments artificially inoculated with Fusarium spp. will be set up in Germany, Czech Republic, North Italy and Romania. Descriptors with probable relevance for Fusarium infection in the field will be observed. Seed infection with Fusarium will be scored. Samples without visible symptoms will be checked for contamination by mycotoxins with analytics of increasing sensitivity.

 

Quality Analysis

Samples of harvested grain will be sent for quality analysis to partners with specialised labs. Backbone for the analytical activity will be the near infrared reflectance spectroscopy (NIRS). It will be applied for the bulk of samples harvested in field experiments. Chemical analysis will be applied to a limited number of samples, mainly for NIRS calibration in cases of protein and fat, where NIRS is well established. In cases of -glucan and phenols orthogonal sets of accessions will be analysed from respective field experiments in three environmentally contrasting regions in Europe (Nordic, Mediterranean, Balkans). Avenin patterns will be determined for all accessions, minerals and trace elements for a limited number of samples.

 

Cold tolerance

Cold tolerance will be observed in the field and under controlled conditions in climate chambers.

 

Documentation

All project activity will be supported by a project database and web portal. All results will be entered in the European Avena database and made accessible to the public in a Avena crop portal.
