Mapping candidate genes for Fusarium ear rot resistance

摘要

Fusarium ear rot is one of the most important diseases of maize because Fusarium verticillioides produces mycotoxins fumonisins. Resistance to Fusarium ear rot is polygenic with nearly complete dominance or overdominance of resistance alleles. The availability of molecular markers associated to resistance genes could be a successful strategy to select lines resistant to F. verticillioides. Mapping of quantitative trait loci (QTLs) provides a powerful method to understand the genetic relationships between correlated traits.
