Tropical maize can be used to diversify the genetic base of temperate germplasm and help
create climate-adapted cultivars. However, tropical maize is unadapted to temperate …

Crop species exhibit an astounding capacity for environmental adaptation, but genetic
bottlenecks resulting from intense selection for adaptation and productivity can lead to a …

Tropical strains of maize (Zea mays subsp. mays L.) flower very late in temperate
environments. This is a barrier to maize diversification and improvement in regions where a …

Maize (Zea mays L.) is one of few crops that can offer significant genetic gains with the
utilization of genetic diversity. Genetically broad-based germplasm has the potential to …

The geographical distribution of many crop species spans far beyond their centers of origin
and the native range of their wild ancestors. Maize is exemplary of this adaptability, which …

Context Tropical maize lines are known to have extended flowering times when grown in
northern temperate environments, a response largely due to the prolonged day length. This …

Maize (Zea mays L.), the third most widely cultivated cereal crop in the world, plays a critical
role in global food security. To improve the efficiency of selecting superior genotypes in …

Genomic selection studies usually use few environmental models to predict progenies from
biparental crosses. However, in a maize breeding program, numerous crosses need to be …

Background Success in any genomic prediction platform is directly dependent on
establishing a representative training set. This is a complex task, even in single-trait single …

Maize cultivars with broad thermal adaptation may be useful in areas where the crop
experiences large fluctuations in temperature, or when a cultivar is targeted for several …
