Unlocking soybean potential: genetic resources and omics for breeding.

Abstract

Soybean (Glycine max) is a vital foundation of global food security, providing a primary source of high-quality protein and oil for human consumption and animal feed. The rising global population has significantly increased the demand for soybeans, emphasizing the urgency of developing high-yield, stress-tolerant, and nutritionally superior cultivars. The extensive collection of soybean germplasm resources-including wild relatives, landraces, and cultivars-represents a valuable reservoir of genetic diversity critical for breeding advancements. Recent breakthroughs in genomic technologies, particularly high-throughput sequencing and multi-omics approaches, have revolutionized the identification of key genes associated with essential agronomic traits within these resources. These innovations enable precise and strategic utilization of genetic diversity, empowering breeders to integrate traits that improve yield potential, resilience to biotic and abiotic stresses, and nutritional quality. This review highlights the critical role of genetic resources and omics-driven innovations in soybean breeding. It also offers insights into strategies for accelerating the development of elite soybean cultivars to meet the growing demands of global soybean production.
