Interpretive Summary:

Technical Abstract: For most traits, genetic and biochemical information on metabolic pathways is extremely limited, and therefore, it is difficult to interpret quantitative trait locus results in terms of regulatory and structural genes, duplicate function loci, feedback inhibition, branched pathways, or or other phenomena affecting trait expression. We have exploited a unique research system to analyze the genetic control of a quantitative trait of economic importance (antibiosis to the corn earworm) and to interpret the results in terms of the well-characterized flavonoid and phenylpropanoid pathways. From these studies, we have documented a number of fundamental genetic mechanisms for the genetic control ofquantitative traits.
