abstract: Crop populations derived from experimental crosses enable the genetic dissection of complex traits and support modern plant
breeding. Among these, multi-parent populations now play a central role. By mixing and recombining the genomes of multiple
founders, multi-parent populations combine many commonly sought beneficial properties of genetic mapping populations. For
example, they have high power and resolution for mapping quantitative trait loci, high genetic diversity and minimal population
structure. Many multi-parent populations have been constructed in crop species, and their inbred germplasm and associated phenotypic
and genotypic data serve as enduring resources. Their utility has grown from being a tool for mapping quantitative trait loci to a means
of providing germplasm for breeding programmes. Genomics approaches, including de novo genome assemblies and gene
annotations for the population founders, have allowed the imputation of rich sequence information into the descendent population,
expanding the breadth of research and breeding applications of multi-parent populations. Here, we report recent successes from crop
multi-parent populations in crops. We also propose an ideal genotypic, phenotypic and germplasm ‘package’ that multi-parent
populations should feature to optimise their use as powerful community resources for crop research, development and breeding.
