Genotype-phenotype models (GPM) of crops represent a significant advancement in understanding the intricate relationship between genetic information and physiological processes in plants. These models are particularly valuable in the context of cropping systems, where they offer insights into how genetic variations influence plant growth and yield. Despite the progress made, there remain substantial gaps in our understanding of how to effectively integrate genetic data into predictive models of plant phenotypes. Recent studies have highlighted the potential of GPMs in plant breeding, especially under varying environmental conditions, yet the complexity of accurately simulating genetic interactions and their phenotypic outcomes continues to pose challenges. The advent of high-throughput phenotyping and advanced genomics tools has provided a wealth of data, but the need for more sophisticated models that can handle this data and predict phenotypic outcomes with higher accuracy is evident.

This research topic aims to showcase the latest developments in genotype-phenotype modeling of plants, with a particular focus on crop plants. The primary objective is to explore how emerging methodologies, such as high-throughput phenotyping, improved genomics tools, and functional-structural plant modeling, can enhance our understanding and application of GPMs. Specific questions to be addressed include how genetic information can be effectively integrated into models to predict phenotypic outcomes, and how these models can be used to accelerate plant breeding processes. Hypotheses to be tested may involve the accuracy of GPMs in simulating the performance of new genotypes under various environmental conditions and the potential of these models to predict ideotypes for future breeding programs.

To gather further insights into the boundaries of genotype-phenotype modeling, we welcome articles addressing, but not limited to, the following themes:

- Development and validation of metabolic network models regulated by genetic information.
- Advances in ecophysiological functional-structural plant models (FSPM) incorporating quantitative trait locus information.
- Population models enabling interactive simulation of genetic processes such as recombination and crossing-over.
- Novel methodologies in high-throughput phenotyping and their integration into GPMs.
- Case studies on the application of GPMs in plant breeding programs.
- Reviews and opinion papers on the current state and future directions of genotype-phenotype modeling
