Sanitary quality of maize (corn) & Mycotoxins

Research Programmes

Selection of maize (corn)

The programmes aim to improve and guarantee good sanitary quality for maize (corn) and finished products.

Identifying fusariosis-tolerant lines

Since fungicides (offering chemical protection of a crop against contamination by a pathogenic fungus) are of only limited effect on Fusaria, hope is based particularly on genetics and the selection of lines which are more tolerant to fungal contaminations and the production of mycotoxins.

Maïsadour Semences' plant breeders have therefore included "tolerance to fusariosis", as a selection criterion alongside other criteria such as yield, starch levels, and so on.

Findings of the study on lines

 

... Using suitable tools

To carry out this work of selecting and creating a mycotoxin-resistant germplasm it was essential, given the lack of reliable methods, to develop and use new, effective tools for all the stages of maize (corn) selection :

Artificial contamination

Methods of analysis

 

... Creating new fusariosis-tolerant hybrids

Appraisers then take over to study tolerance to fusariosis and the production of toxins in the varieties being developed.
They have a vast experiment network: the varieties are tested throughout Europe (in over 60 different locations), where the effects of fusariosis, which are mainly dependant on the climate, are variable. Sanitary analyses of grains and dosage levels of toxins produced by Fusaria are carried out routinely every year on several hundred samples taken from the experiment network.

Organisation of the research programmes

The programmes are organised around criteria regulating the sanitary conditions in the field

REVIEWING THE BASICS

Which fungi are likely to synthesize mycotoxins in maize (corn) grains and which toxins are they likely to produce? Are there answers to these questions? Please consult the introductory section:
