Maize breeding focuses at NQLD (high rainfall area) & South, central (drier) environments
As you know crop grow in various type of contrasting environments. Plant breeders target a certain population of environment which correspond to the set of env. that crops might experienced within a defined geographic area that they’re interesting in. Breeders usually target a certain population of environments which reflect/integrate/gather/correspond the different environments to which their released cultivar will be exposed to. Comstock gave a definition of the TPE in 1977, saying that they correspond to the complete set of environment types in which crop can be grown within a geographical ares.

Traits like ‘stay green’ may help with terminal stress Matching phenology may require developing quick maturing genotypes G-M for each target environment to enhance productivity and profitability of growing maize
