ChromaX: a fast and scalable breeding program simulator.

Abstract

ChromaX is a Python library that enables the simulation of genetic recombination, genomic estimated breeding value calculations, and selection processes. By utilizing GPU processing, it can perform these simulations up to two orders of magnitude faster than existing tools with standard hardware. This offers breeders and scientists new opportunities to simulate genetic gain and optimize breeding schemes. The documentation is available at https://chromax.readthedocs.io. The code is available at https://github.com/kora-labs/chromax.
