Abstract only

The International Maize and Wheat Improvement Center (CIMMYT) has a global mandate to improve maize and wheat production in developing countries. To help prioritize breeding objectives, 'mega environments' (ME) were defined as areas of similar crop adaptation and grain types. The concept has since proven useful to agronomy, entomology, pathology, and economics. Previously, ME's were mapped primarily by using variables indirectly related to plant response to the environment (e.g., latitude, elevation). Current GIS tools and spatial databases allow use of diagnostic variables estimated from interpolated climate data. We present a preliminary classification based on cluster analysis of planting date dependent day length, and growing season temperature and precipitation from over 240 maize production locations
