German researchers decoded the European maize genome. In comparison to North American maize lines, they discovered variations that underlie phenotypic differences and may also contribute to the heterosis effect. A better understanding of the effect could impact breeding for higher yields. For cultivation of maize in areas with low yields and for challenges imposed by the climate change these observations may be of particular importance.
