The most desirable control strategy for Fusarium ear rot and fumonisin contamination is the use of resistant corn genotypes. Results from projects previously funded by the Corn Growers of NC showed that genotypes differ in their resistance, but that none has sufficient resistance to control the disease, and that heritability of resistance is high enough for breeding to be effective. A previously funded proposal screened demonstrated the potential use of genomic selection for the improvement of ear rot and fumonisin resistance in corn. In this current proposal, we propose to build on previous results by developing a protocol to obtain high throughput genotyping data in a rapid and relatively inexpensive way. Once this protocol is established, we can implement genomic selection two seasons per year instead of one season every two years, as we currently do with phenotypic selection. Although one cycle of genomic selection is not better than one cycle of selection based on field evaluations, four cycles of genomic selection are expected to be better than the one cycle of phenotypic selection that can be conducted in the same time frame. Also, if we can develop a sufficiently inexpensive genotyping protocol, we can reduce costs, allowing more lines to be evaluated using genomic selection.

The project funded will involve the selection of backcross inbred lines of corn containing resistance to Fusarium ear rot and fumonisin contamination combined with superior combining ability for grain yield. The research will also include fine-mapping a photoperiod response gene from tropical corn. Results from this research will provide superior genetic material for corn breeders and geneticists.
