Phytotoxic effect of deoxynivalenol and gibberella ear rot resistance of com
Natural Toxins, 1995AbstractThe 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.

Incidence of maize ear rot in western Kenya
International Journal of Pest Management, 1994Abstract Twenty‐five maize genotypes were planted at Kitale and Kakamega, western Kenya, in 1987, 1988, and 1989. Estimates of percent diseased ears, expressed as a disease index (DI), were made 8, 14, and 20 weeks after midsilk. There were no differences (P=0.05) among years nor between locations.

Inoculation of Maize Ears with Fusarium graminearum to Study Gibberella Ear Rot
Cold Spring Harbor ProtocolsMaize is an important food and fuel crop globally. Ear rots, caused by fungal pathogens, are some of the most detrimental maize diseases, due to reduced grain yield and the production of harmful mycotoxins. Mycotoxins are naturally occurring toxins produced by certain fungal species that can cause acute and chronic health issues in

Maize Kernel Antioxidants and Their Potential Involvement in Fusarium Ear Rot Resistance
Journal of Agricultural and Food Chemistry, 2013The potential involvement of antioxidants (α-tocopherol, lutein, zeaxanthin, β-carotene, and ferulic acid) in the resistance of maize varieties to Fusarium ear rot was the focus of this study. These antioxidants were present in all maize kernel stages, indicating that the fumonisin-producing fungi (mainly Fusarium verticillioides and Fusarium ...

QTL mapping of resistance to Gibberella ear rot in maize
Molecular Breeding, 2020Gibberella ear rot (GER), caused by the fungal pathogen Fusarium graminearum, is becoming one of the most prominent pathogens responsible for ear rot in maize. In this study three F2 populations, F2-C, F2-D, and F2-J, and their corresponding F2:3 families, were constructed by crossing three highly GER-resistant inbred lines—Cheng351, Dan598, and JiV203—

Pedigree selection for Gibberella ear rot resistance in maize
Euphytica, 2005The pedigree method is often used for developing inbred lines in maize (Zea mays L.). This study was conducted to assess the effectiveness of pedigree selection for improving resistance to Gibberella ear rot in four maize populations. Selection was based on the severity of ear rot symptoms after inoculation with macroconidial suspensions of Fusarium ...

An improved understanding of Diplodia ear rot in Kentucky corn
2022Stenocarpella maydis and Stenocarpella macrospora are both causal agents of Diplodia ear rot (DER) of corn in the U.S. The current prevalence and distribution of each is unknown worldwide. Signs and symptoms of DER include white mold on and between kernels, bleached husks, and pycnidia visible in the cob pith. The term hidden Diplodia describes when no

Study of maize resistance to Gibberella Ear Rot
2006Gibberella 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.
