Qualitative Resistance to Exserohilum Turcicum Race 2 in Maize (Corn, Genetics)
The fungus Exserohilum turcicum causes northern leaf blight of maize (Zea mays L.) and it is found in most maize growing areas of the world. This disease has been controlled effectively for over 15 years by qualitative and quantitative resistance. In 1979 a new race of the fungus (race 2) was found …

Evaluation of race population distribution, fungicide sensitivity, and fungicide control of Exserohilum turcicum, the causal agent of northern leaf blight of corn
Northern leaf blight (NLB) of corn, caused by Exserohilum turcicum, is a yield reducing foliar disease common across the north central U.S. Previous race population distribution studies identified five physiological races present in the U.S., prior to 1995. For this study, 156 E. turcicum isolates …

Status of Northen Leaf Blight, Phaeosphaeria maydis Leaf Spot, Southern Leaf Blight, Rust, Maize Streak Virus and Physiologic Specialization of Exserohilum turcicum in Kenya
Exserohilum turcicum, Phaeosphaeria maydis, Bipolaris maydis, Puccinia polysora, Puccinia sorghi and maize streak virus were the most serious maize pathogens found in Kenya during a 1995/96 survey of 65 farms representing all the agro-ecological zones. Exserohilum turcicum - induced blight was …

Effect of Resistance Type on the Development of and Yield Losses Due to Northern Corn Leaf Blight
… of northern leaf blight (NLB), caused by Exserohilum turcicum, was studied on three dent corn (Zea mays L.) hybrids: A619 x A632, B73 x Oh545 and Mo17 x B73. Two nearly isogenic versions of each hybrid were used, one version carrying the resistance gene Ht1 and the second carrying the …

Epidemiological Studies of Northern Corn Leaf Blight on Corn Inbreds: Loss Assessment and Disease Modeling
… Northern corn left blight (NCLB), caused by Exserohilum turcicum, an important disease of maize, has provided a model system for evaluating the relationships between disease and components of yields of inbreds. The effects on yields of two detasseling methods and the efficacy of a new …

The Genetic Architecture Of Quantitative Disease Resistance In Maize
… (NLB, caused by Setosphaeria turcica L. anamorph Exserohilum turcicum). The maize nested association mapping (NAM) population, a reference design population consisting of 4,630 recombinant inbred lines, was evaluated over three environments for quantitative resistance to NLB, giving highly …

Interactions between oxidative stresses in corn
… spot (Physoderma maydis), northern leaf blight (Exserohilum turcicum), and gray leaf spot (Cercospora zeae-maydis). Within a growing season disease severity was highly genotype-dependent; however, there were modest genotype-independent ozone effects, mostly significant under high-disease pressure …

Identifying loci conferring quantitative disease resistance in sorghum and maize against fungal foliar pathogens
… are both caused by the hemibiotrophic fungus Exserohilum turcicum. Both qualitative and quantitative resistance against E. turcicum have been described in maize. In contrast, the genetic architecture of resistance against E. turcicum in sorghum is poorly understood. Maize and sorghum are …
