A generalized statistical framework to assess mixing ability from incomplete mixing designs using binary or higher order variety mixtures and application to wheat

•Statistical analyses for variety mixtures have made little progress in recent years.•Novel models are proposed to study mixing ability in incomplete designs.•The models account for inter and intra-genotypic interactions within mixtures.•The framework handles mixtures with any order and proportions of components.•This framework was shown to be relevant on wheat mixture trial analysis.
