Molecular Basis of Resistance to Fusarium Ear Rot in Maize
The impact of climate change has been identified as an emerging issue for food security and safety, and the increased incidence of mycotoxin contamination in maize over the last two decades is considered a potential emerging hazard. Disease control by chemical and agronomic approaches is often ineffective and increases the cost of production; for this reason the exploitation of genetic resistan...
متن کاملGenetic of resistance to ear rot causal agent (Fusarium moniliforme) in quality protein maize (QPM) using line×tester analysis
Breeding for QPM ear rot resistant cultivars could offer a reliable environmental and economic control of mycotoxins especially for the resource-poor communities that require inexpensive protein diets. This research aims at evaluating a testcross of QPM inbreds with ear rot resistant cultivars to develop resistant topcrosses with high grain protein quality and yield. Seven QPM inbreds (lines) a...
متن کاملDiallel Analysis of Resistance to Fusarium Ear Rot and Fumonisin Contamination in Maize
The fungus Fusarium verticillioides infects maize (Zea mays L.) ears and kernels, resulting in Fusarium ear rot disease, reduced grain yields, and contamination of grain with the mycotoxin fumonisin. Hybrid maize breeding programs involve selection for both inbred and hybrid performance; the emphasis placed on inbred versus hybrid selection depends on heritability of and the genetic correlation...
متن کاملRhamnolipid Biosurfactant against Fusarium verticillioides to Control Stalk and Ear Rot Disease of Maize
Antifungal activity of rhamnolipids (RLs) has been widely studied against many plant pathogenic fungi, but not against Fusarium verticillioides, a major pathogen of maize (Zea mays L.). F. verticillioides causes stalk and ear rot of maize or asymptomatically colonizes the plant and ears resulting in moderate to heavy crop loss throughout the world. F. verticillioides produces fumonisin mycotoxi...
متن کاملEvaluation of ear rot (Fusarium verticillioides) resistance and fumonisin accumulation in Italian maize inbred lines
Mycotoxin contamination of maize (Zea mays L.) grain is a global threat to the safety of both human food and animal feed. Hence, the development of maize genotypes with reduced mycotoxin accumulation in grain is of major importance. In order to find maize germplasm sources of resistance to Fusarium ear rot, 34 Italian and six public inbred lines were evaluated by means of artificial inoculation...
متن کاملIdentification of Pathogenic Fusarium spp. Causing Maize Ear Rot and Potential Mycotoxin Production in China
Ear rot is a serious disease that affects maize yield and grain quality worldwide. The mycotoxins are often hazardous to humans and livestock. In samples collected in China between 2009 and 2014, Fusarium verticillioides and F. graminearum species complex were the dominant fungi causing ear rot. According to the TEF-1α gene sequence, F. graminearum species complex in China included three indepe...
