Interpretive Summary: Maize is a remarkably diverse species, adapted to a wide range of climatic conditions and farming practices. In this chapter we review the phenotypic and DNA diversity of maize, how it is partitioned among and within geographic regions and ‘races’. We consider how modern sequencing and genomic technologies can be used to study this diversity and incorporate useful genes from diverse maize into temperate-adapted breeding programs.

Technical Abstract: Maize is a remarkably diverse species, adapted to a wide range of climatic conditions and farming practices. The latitudinal range of maize is immense, ranging from 54°N in Alberta, Canada, to 45°S in the province of Chubut, Argentina. In terms of altitude, maize is cultivated from sea level to 4000 m. In Mexico alone, maize is grown in arid regions receiving 400 mm of rain to tropical environments with 3555 mm of precipitation during their growing season. In this chapter we review the phenotypic and DNA diversity of maize, how it is partitioned among and within geographic regions and ‘races’. We consider how modern sequencing and genomic technologies can be used to study this diversity and incorporate useful genes from diverse maize into temperate-adapted breeding programs.
