Gene-based modeling

With the rapidly increasing availability of data on DNA sequences of individual cultivars or breeding lines, there is growing interest in using this incredible data resource to improve crop model development and applications. Similarly, advances in understanding of the control of plant processes at the molecular level suggests opportunities to strengthen how mechanisms are represented in crop models. These interests have given rise to a broad area of activities termed “gene-based modeling.” Topics of interest to DSSAT users and system modelers can pertain to four activities:

  • Estimation of genotype-specific model parameters (GSPs)
  • Improved representation of crop processes
  • Guiding genetic dissection of crop processes through analysis of GSPs as phenotypes
  • Use of genetic data for genetically realistic sensitivity analyses

A more extensive treatment of these topics is given here.
