Maize Aflatoxin Accumulation Segregates with Early Maturing Selections from an S2 Breeding Cross Population
Maize breeders continue to seek new sources of aflatoxin resistance, but most lines identified as resistance sources are late maturing. The vast difference in flowering time makes it hard to cross these lines with proprietary commercial lines that mature much earlier and often subjects the reproductive phase of these resistant lines to the hottest and driest portion of the summer, making silkin...
متن کاملAflatoxin Accumulation in a Maize Diallel Cross
Aflatoxins, produced by the fungus Aspergillus flavus, occur naturally in maize. Contamination of maize grain with aflatoxin is a major food and feed safety problem and greatly reduces the value of the grain. Plant resistance is generally considered a highly desirable approach to reduction or elimination of aflatoxin in maize grain. In this investigation, a diallel cross was produced by crossin...
متن کاملEvaluation of Maize Germplasm for Resistance to Aflatoxin Accumulation
Aflatoxin contamination of maize grain threatens human food and animal feed safety. Breeding for reduced grain aflatoxin accumulation is one of the best strategies presently available to lower grain aflatoxin accumulation. Previously identified sources of germplasm with reduced grain aflatoxin accumulation are excessively tall and late maturing. The objective of this research was to screen germ...
متن کاملMaize (Zea mays L.) yield and aflatoxin accumulation responses to exogenous glycinebetaine application
Exogenously applied glycinebetaine (GB) accumulates at high levels in maize (Zea mays L.). Under water deficit and high temperature conditions GB application produces yield benefits. These sub-optimum conditions often result in high levels of aflatoxin accumulation which reduces grain quality. A 3-year (2008, 2009 and 2010) field experiment was conducted to determine the effects of GB on ma...
متن کاملAflatoxin in Maize: An African Perspective
Preand postharvest contamination of aflatoxin in maize is a major health deterrent for people in Africa where maize production has increased dramatically. This chapter highlights management options for preand postharvest toxin contamination in maize. Sound crop management practices are an effective way of avoiding, or at least diminishing, infection by Aspergillus jlavus and subsequent aflatoxi...
