Study of maize resistance to Gibberella Ear Rot

2006
Gibberella Ear Rot caused by the fungus Fusarium graminearum Schwabe is a serious disease of maize (Zea mays L) grain in Croatia.The two year trials consisted of screening 145 maize lines for resistance and testing 24 maize hybrids under conditions of artificial ear inoculation into the silk channel with F. graminearum.

Maize resistance to gibberella ear rot: symptoms, deoxynivalenol, and yield¹

Canadian Journal of Plant Pathology, 2001
To investigate the effect of different environments on maize resistance to gibberella ear rot, disease symptoms, deoxynivalenol (DON) concentration, and grain yield were measured in three maize (Zea mays L.) inbred lines and five hybrids, from 1994 to1996, at six locations in eastern Canada.

Crop rotation and nitrogen effects on maize susceptibility to gibberella (Fusarium graminearum) ear rot

Plant and Soil, 2001
An experiment was established in 1992 in eastern Ontario, Canada to determine the effects of crop rotation (continuous maize, soybean-maize and alfalfa-maize) and nitrogen (N) amendment [0, 100 and 200 kg N ha−1 of fertilizer (NH4NO3), and 50 and 100 Mg ha−1 (wet wt.) each of stockpiled and rotted dairy manure] on maize production and soil properties ...

Inheritance of resistance to Gibberella ear rot and deoxynivalenol contamination in five flint maize crosses

Plant Breeding, 2011
With 1 figure and 2 tablesAbstractGibberella ear rot (GER) of maize caused by Fusarium graminearum leads to contamination of grains with mycotoxins such as deoxynivalenol (DON), thus reducing the quality of food and feed. A generation means analysis was conducted to estimate gene effects influencing the resistance to GER and DON contamination in flint ...

A 4‐Year Study of the Association Between Gibberella Ear Rot Severity and Deoxynivalenol Concentration

Journal of Phytopathology, 1996
AbstractTo determine the association between visual disease severity and deoxynivalenol (DON) concentration in Fusarium graminearum silk‐inoculated maize ears, 23 Ontario hybrids were assessed in 1989, 1991, 1992, and 1993. The relationship was exponential and consistent between years.

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.).

Molecular mapping of QTLs for resistance toGibberellaear rot, in corn, caused byFusarium graminearum

Genome, 2005
Gibberella ear rot, caused by the fungus Fusarium graminearum Schwabe, is a serious disease of corn (Zea mays) grown in northern climates. Infected corn is lower yielding and contains toxins that are dangerous to livestock and humans. Resistance to ear rot in corn is quantitative, specific to the mode of fungal entry (silk channels or kernel wounds ...

A guanylyl cyclase-like gene is associated with Gibberella ear rot resistance in maize (Zea mays L.)

Theoretical and Applied Genetics, 2007
Gibberella ear rot, caused by the fungal pathogen Fusarium graminearum Schwabe, is a serious disease of maize (Zea mays L.) grown in northern climates. The infected maize grain contains toxins that are very harmful to livestock and humans. A maize gene that encodes a putative 267-amino acid guanylyl cyclase-like protein (ZmGC1) was characterized and ...

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 ...

Colocalization of QTL for Gibberella Ear Rot Resistance and Low Mycotoxin Contamination in Early European Maize

Crop Science, 2011
Gibberella ear rot (GER) of maize (Zea mays L.) caused by Fusarium graminearum Schwabe is a major disease in Europe that reduces grain yield and leads to contamination with deoxynivalenol (DON) and zearalenone (ZEA), two important mycotoxins. The objectives of our study were to (i) estimate quantitative‐genetic parameters for GER severity and DON and ...
