These studies were carried out simultaneously with the study carried out on lines begun in 2001. The maize (corn) hybrids being developed and varieties marketed by Maïsadour Semences were analysed in each test series in order to determine whether or not tolerance to Fusarium is hereditary, and to determine the characteristics of the different varieties. A network of experiments throughout EuropeThe study concerned 96 hybrids, both early and late varieties tested in the extensive experiment network (comprising over 60 locations) in a wide variety of situations.

The effects of fusariosis depend largely on the climate. The occurrence of F. graminearum is therefore observed mostly on early hybrids and F. Liseola mostly on late hybrids. To characterise the tolerance of the different varieties, three types of analysis were routinely carried out each year on several hundred samples from the network (1205 analyses carried out over four series of studies): results for attacks on ears (Ear Visual), sanitary analyses of grains and dosages of toxins produced by Fusaria |

Tolerance of maize (corn) hybrids to F. Liseola
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.
