| Abstract: | Maize ear rot reduces yield and quality of the grain greatly.The contamination of the grain with mycotoxins produced by the ear rot fungal pathogens is hazardous to humans and animals.Resistance to maize ear rot and mycotoxin contamination has shown to be complex quantitative traits,which are controlled by several genes of small effects and greatly affected by the environment.This review briefly introduced the occurrence and distribution of maize ear rot and summarized the main mycotoxins produced by different causal fungi.Recent advances in locating quantitative trait loci and candidate genes on the maize genome associated with mycotoxin resistance was also presented.Application of genomic selection in resistance breeding against ear rot and mycotoxin contamination was reviewed.In addition,the challenges and solutions for gene identification and resistance breeding was discussed.The aim of this study was to provide theoretical guidance for prevention and control of ear rot and mycotoxin contamination in maize. |
