Phytotoxic effect of deoxynivalenol and gibberella ear rot resistance of com

Natural Toxins, 1995
AbstractThe Fusarium graminearum mycotoxin deoxynivalenol was shown to be more phytotoxic to com senotypes susceptible to gibberella ear rot than resistant genotypes. The toxin caused greater damage to the membranes of the susceptible genotypes, as evidenced by the release of Na and K ions into solution.

Genome-wide association study and molecular marker development for susceptibility to Gibberella ear rot in maize

Theoretical and Applied Genetics
Sixty-nine quantitative trait nucleotides conferring maize resistance to Gibberella ear rot were detected, including eighteen novel loci. Four candidate genes were predicted, and four kompetitive allele-specific PCR markers were developed. Maize Gibberella ear rot (GER), caused by Fusarium graminearum, is one of the most devastating diseases in maize ...

Relationship between kernel drydown rate and resistance to gibberella ear rot in maize

Euphytica, 2014
Development of gibberella ear rot (GER) resistant genotypes in maize is important to reduce yield loss and most importantly to avoid mycotoxin contamination of food and feed. The objective of the current study was to investigate the effect of kernel drydown rate (KDD) on GER disease development and to test whether using KDD as an indirect selection ...

Low validation rate of quantitative trait loci for Gibberella ear rot resistance in European maize

Theoretical and Applied Genetics, 2016
Six quantitative trait loci (QTL) for Gibberella ear rot resistance in maize were tested in two different genetic backgrounds; three QTL displayed an effect in few near isogenic line pairs. Few quantitative trait loci (QTL) mapping studies for Gibberella ear rot (GER) have been conducted, but no QTL have been verified so far.

Fusarium meridionale is more aggressive and competitive than F. graminearum as a causal agent of Gibberella Ear Rot of maize in Brazil

, 2020
In Brazil, Gibberella ear rot (GER) of maize is caused mainly by Fusarium meridionale (Fmer), while F. graminearum (Fgra) is a minor contributor. To test the hypothesis that Fmer is more aggressive than Fgra on maize, three experiments were conducted in ...

Larval western bean cutworm feeding damage encourages the development of Gibberella ear rot on field corn

Pest Management Science, 2016
AbstractBACKGROUNDA 2 year study was conducted to determine whether western bean cutworm (Striacosta albicosta Smith) (WBC) larval feeding damage increases severity of the fungal disease Gibberella ear rot [Fusarium graminearum (Schwein.) Petch] in field corn (Zea mays L.).

A combination of QTL mapping and GradedPool-Seq to dissect genetic complexity for Gibberella ear rot resistance in maize using an IBM Syn10 DH population.

Plant Disease, 2022
Gibberella ear rot (GER) caused by Fusarium graminearum (teleomorph Gibberella zeae) is one of the most devastating maize diseases that reducing grain yield and quality worldwide. Utilization of host genetic resistance has become one of the most suitable

Effect of pydiflumetofen on Gibberella ear rot and Fusarium mycotoxin accumulation in maize grain

, 2021
In Ontario, Canada, Fusarium graminearum Schwabe causes Gibberella ear rot (GER) in maize, resulting in the accumulation of mycotoxins, mainly deoxynivalenol (DON), DON-3-glucoside (DON-3G) and zea...

Evaluating commercial maize hybrids for resistance to gibberella ear rot

European Journal of Plant Pathology, 1997
An integral component of breeding maize for resistance to Fusarium graminearum ear rot is the identification of resistant genotypes. Since natural infection is not consistent from year to year, maize researchers must use manual techniques to inoculate the plant material with fungal spores.
