Abstract: To assess performance of genotypes, crop improvement programs require evaluation of materials under different environmental conditions. Testing programs have an opportunity to be more efficient by carefully selecting testing sites that permit evaluation over a broad range of environments. What methods and tools can be used to guide evaluation of genotypes? This project demonstrates the use of agronomic and environmental modeling of possible locations for assessing genotypes within a phenotyping network. Conditions of more than fifty candidate testing sites were evaluated using data on climate, soils, crop production and other variables. For each candidate site, climate information was developed to get a sense of the water balance and the seasonal variation in rainfall, evapotranspiration, temperature and length of the growing season. Crop production, soil and climatic conditions surrounding each candidate site were derived from digital maps using overlay techniques. A set of existing climate analysis tools and a research atlas have been adapted and modified for use by GCP researchers. The information derived from this study will be used to support decisions on the deployment and testing of genotypes in crop improvement programs.
