Chapter synopsis:

This chapter describes the Decision Support System for Agrotechnology Transfer (DSSAT) Crop Modeling ecosystem, its origin, advancements in model capabilities, addition of models for new crops, examples of model simulations of genetic improvement, and tools for data entry, calibration, analysis, and applications. Examples of model applications are given with emphasis on genetic improvement especially under the impacts of climate change.
