Overview

Review outlines genomic prediction and mate allocation strategies in sugarcane breeding, highlighting integrated mixed models to accelerate genetic gain across complex polyploid genomes.

Key Points

To review the biological, statistical, and genomic challenges constraining sugarcane improvement and propose an integrated genomic prediction framework for early-stage selection and cross allocation.
Examined multi-stage sugarcane selection schemes, focusing on progeny, clonal, and final assessment trials in the Australian breeding system.
Evaluated statistical hurdles, including family plot means, spatial heterogeneity, genotype-by-environment interactions, non-additive variation, and allele-dosage estimation in polyploid and aneuploid genomes.
Synthesized methods for genomic prediction of cross performance, constrained mate allocation algorithms, and stage-integrated mixed models.
Identified that genomic selection is currently underutilized at critical early decision stages, including family selection and parent crossing, due to complex polyploid genetics and trial design limitations.
Demonstrated that combining genomic cross-performance predictions with constrained mate allocation accounts for non-additive effects while controlling inbreeding and coancestry.
Proposed a decision-centered, single-step mixed-model framework that connects early progeny testing with clonal assessment to optimize parent recycling and selection accuracy.
