Researchers develop new software to simulate breeding programs

A team of researchers at the University of Göttingen has developed an innovative software program for the simulation of breeding programs.

The "Modular Breeding Program Simulator" (MoBPS) enables the simulation of highly complex breeding programmes in animal and plant breeding and is designed to assist breeders in their everyday decisions.

Furthermore, the program is intended to be a cornerstone for further studies in breeding research in Göttingen. In addition to purely economic criteria in breeding, the research team is striving for goals such as sustainability, conservation of genetic diversity and improved animal welfare. The software was presented in the journal G3 Genes, Genomes, Genetics.

By simulating breeding programmes, conclusions can be drawn about genetic improvements. In fact, potentially problematic issues such as inbreeding or adverse effects on the health of the animals can also be identified at an early stage."

Pook is the main developer of MoBPS. The software offers opportunities to realistically model common processes in breeding such as selection, reproduction and data-collection (eg DNA information, trait observations). At the same time, it can simulate millions of matings of animals with certain features in just a few minutes.

"From the simulation of simple maize-breeding programmes, to increased consideration of bone stability in horse breeding, to the simulated development of red deer populations in Baden-Württemberg over the last 200 years, everything has been done," said Pook.

The next goal of the research team is to develop an additional module for MoBPS that can automatically optimise breeding programmes with a large number of variables and under given constraints.
