Agricultural heterosis was observed nearly 100 years ago when hybrid plants out yielded their inbred parents and today this "hybrid vigor" is a major provider for global food production.The genetic basis of heterosis has been debated with respect to the relative importance of dominant,overdominance and epistasis where one of the problems has been the use of whole genome segregating populations where interactions often mask the effects of individual quantitative trait loci (QTL).
