The review discusses mining crop haplotypes for dissecting complex traits and enhancing genomics-assisted breeding, providing avenues for faster breeding of high-yielding cultivars to adapt to future climates. It highlights the vital role of genomics-assisted breeding in improving crop breeding efficiency and delivering better varieties.
In this Review, Bhat et al. highlight ways to mine crop haplotypes and apply them for dissecting complex traits and genomics-assisted breeding (GAB) approaches. This Review presents new avenues to discover superior haplotypes and assemble them in targeted manner in crop breeding for faster delivery of high-yielding cultivars with better adaptation to future climates. Climate change with altered pest-disease dynamics and rising abiotic stresses threatens resource-constrained agricultural production systems worldwide. Genomics-assisted breeding (GAB) approaches have greatly contributed to enhancing crop breeding efficiency and delivering better varieties. Fast-growing capacity and affordability of DNA sequencing has motivated large-scale germplasm sequencing projects, thus opening exciting avenues for mining haplotypes for breeding applications. This review article highlights ways to mine haplotypes and apply them for complex trait dissection and in GAB approaches including haplotype-GWAS, haplotype-based breeding, haplotype-assisted genomic selection. Improvement strategies that efficiently deploy superior haplotypes to hasten breeding progress will be key to safeguarding global food security.
