Analysis Of Clinal Variation In Maize: Implementation OfAn Experimental Framework For Studying Crop Adaptation

http://www.maizeatlas.org 2011-67003-30342

Objective

Approach

Create knowledge, approaches and resources for adapting crops to new environments

Develop an integrated experimental framework to study barriers to adaptationElucidate the genetic basis

of selection response for environmental adaptationProduce new genetic and

genomic resources and analytical methods for plant

breeding

ImpactEnhance the ability to harness untapped gene diversity for the

development ofclimate-resilient germplasm
