Poster summary
- This poster presents an innovative approach to enhancing crop model (CM) calibration for wheat breeding programs. It addresses challenges in wheat production and current breeding limitations by integrating proximal and remote sensing (PRS) data with field measurements. The study, conducted at CIMMYT's CENEB in Mexico, compared 14 wheat genotypes under various environmental conditions. Using DSSAT's GLUE tool, the research evaluated two parameterization scenarios: integrated PRS-field data and field-based measurements alone. Results show that the integrated approach improves CM accuracy, with lower RMSE and higher R² values in most conditions. The poster highlights the importance of time-series data for improving crop growth simulations and suggests implementing PEST software for future calibration of PRS time-series data. This research demonstrates the potential of integrating PRS data and CMs to enhance wheat breeding efficiency and expand crop performance predictions across diverse environments.
