Led by Jana Obsteter and Thiago P. Oliveira Summary Software that implements a method for partitioning genetic trends to quantify the sources of genetic gain in breeding programmes. The partitioning method is described in Garcia-Cortes et al. (2008) and AlphaPart implementation in Obsteter et al. (2021). The R implementation is available on CRAN and its development is hosted on GitHub. https://CRAN.R-project.org/package=AlphaPart https://github.com/AlphaGenes/AlphaPart Garcia-Cortes et al.
