Objective:
Identify the genetic regions underlying maize adaptation to highland growing conditions.
Approach:
We will conduct QTL mapping studies of one Mexican and one South American population, each derived by crossing a landrace adapted to lowland conditions with a landrace adapted to highland conditions. The populations were phenotyped for an array of agronomic, fitness, and elevation-related phenotypes at three field locations in Mexico: lowland, intermediate, and highland. The population will be genotyped with a custom SNP array. Several iterations of QTL analysis will be conducted: on individual traits, individual traits adjusted for covariates such as flowering time, and multiple traits simultaneously.
