Interpretive Summary:

Technical Abstract: Using a quantitative locus (QTL) methodology in two segregating maize populations, we identified chromosome regions controlling concentration of maysin, a C-glycosyl flavone, in silks and antibiosis to the corn earworm in dried silk bioassays. Results were interpreted in terms of known loci of the flavonoid metabolic pathway.
