Group A

 

 

Earliness: Early Maize (corn)
Tolerance of maize (corn) hybrids to F. Graminearum

Group B

 

 

NB: the occurrence of F. graminearum in the tests does not necessarily imply that mycotoxins were produced. The result for the intensity of attack on the ears at the time of harvesting (Ear Visual) is not sufficient evidence to draw conclusions on the sensitivity of a maize (corn) variety to the development of mycotoxins.

Few tests from the entire Northern European network show the development of F. graminearum. The fusariosis due to contamination by this parasite is therefore not very common. Amongst the test plots affected by disease, discrimination was used to show that Maïsadour Semences' varieties are very tolerant to Fusarium graminearum.

 

Earliness: Semi-early Maize (corn)
Tolerance of maize (corn) hybrids to F. Liseola

Group C

 

 

NB: the occurrence of F. Liseola in the tests does not necessarily imply that mycotoxins were produced. The result for the intensity of attack on the ears at the time of harvesting (Ear Visual) is not sufficient evidence to draw conclusions on the sensitivity of a maize (corn) variety to the development of mycotoxins.

In earliness group C, the effects of parasites due to F. Liseola remained low for all four years of the tests. Overall an excellent tolerance is observed for Maïsadour Semences' varieties. These results have not yet been confirmed in situations where the effects of F. Liseola are greater.

Earliness: Very Late Maize (corn)
Tolerance of maize (corn) hybrids to F. Liseola

Group G

 

 

NB: the occurrence of F. Liseola in the tests does not necessarily imply that mycotoxins were produced. The result for the intensity of attack on the ears at the time of harvesting (Ear Visual) is not sufficient evidence to draw conclusions on the sensitivity of a maize (corn) variety to the development of mycotoxins.

The later the varieties, the more the growing areas correspond to situations where the effects of European corn borer (pyrale) are high. A correlation is observed with the sensitivity of the genetic material to F. Liseola.
