maxRgain

maxRgain-package

<code>maxRgain</code> is a package that optimizes polyclonal selection using integer programming. The optimization aims to select groups of clones while maximizing genetic gains and simultaneously complying with user-defined constraints on several traits. This method is described in Surgy, S., Cadima, J. &amp; Gonçalves, E. (2025) Integer programming as a powerful tool for polyclonal selection in ancient grapevine varieties. Theor Appl Genet 138, 122 . tools:::Rd_expr_doi("10.1007/s00122-025-04885-0")
Some examples from the publication are included.

Implements an Integer Programming-based method for optimising genetic gain in polyclonal selection, where the goal is to select a group of genotypes that jointly meet multi-trait selection criteria. The method uses predictors of genotypic effects obtained from the fitting of mixed models. Its application is demonstrated with grapevine data, but is applicable to other species and breeding contexts. For more details see Surgy et al. (2025) <doi:10.1007/s00122-025-04885-0>.
