Heterosis is prevalent for multiple traits in diverse maize germplasm.

<h4>Background</h4>Heterosis describes the superior phenotypes observed in hybrids relative to their inbred parents. Maize is a model system for studying heterosis due to the high levels of yield heterosis and commercial use of hybrids.<h4>Methods</h4>The inbred lines from an...
