摘要

Chickpea (Cicer arietinum L.), a grain legume for global nutritional security, has undergone a profound “orphan-to-pioneer” transformation primarily driven by the rapid advancements in Next-Generation Sequencing (NGS) and high-throughput multi-omics platforms. Following the assembly of the reference genome, the chickpea genomic resource toolkit has expanded immensely to include various molecular markers, high-density Single Nucleotide Polymorphism (SNP) arrays, high density genetic maps, comprehensive transcriptomes, non-coding RNA (ncRNA) profiles, methylomes, pangenomes and super-pangenomes, etc. These genomic resources provide unprecedented access to specific genes and genomic regions, regulating key agronomic traits in chickpea, enabling precision breeding. However, translating these resources into elite cultivars with higher yields and climate resilience remains a challenge. The persistent “genome-to-phenome” gap must be bridged by integrating contemporary genomic technologies with molecular breeding initiatives, in order to accelerate the development of climate-resilient varieties. This review succinctly synthesizes the present state of scientific advancements with regards to genomic resource development and utilization for trait improvement in chickpea. We also highlight the potential challenges which impede the translation of the vast amount of sequence data into practical breeding solutions. In doing so, we propose a roadmap for deploying CRISPR/Cas-mediated genome editing and Genomic Selection (GS) in active breeding pipelines, with the ultimate goal of developing high-yielding, climate-resilient chickpea cultivars for sustainable agriculture.
