Abstract

Securing agricultural genetic resources has become increasingly difficult due to climate change, urbanization, Changes in food consumption patterns, and the expansion of large-scale agriculture, posing a threat to future food security. RDA Genebank in South Korea conserves 216,484 genetic resources, including foods, horticultural, and special-use crops such as rice, wheat, soybeans, peppers, sesame, and safflower. To evaluate its diversity globally, a comparison was conducted with Genesys, which holds 2,354,629 resources. RDA Genebank showed lower Shannon-Wiener, richness, evenness, and crop utilization indices compared to Genesys, primarily due to higher concentration of resources of food crops such as rice, wheat, and barley relative to fewer species. The diversity of agricultural genetic resources is closely linked to securing and preserving indigenous resources. An analysis of 41,998 Korean-origin resources in the RDA Genebank confirmed that a larger collection of species positively impacts biodiversity preservation efforts. To enhance biodiversity in agricultural genetic resources, it is crucial to establish cooperative systems for sharing genetic resource information among global institutions and ensure the stable acquisition of physical resources. Furthermore, ongoing efforts to investigate, secure, and utilize indigenous resources for breeding and crop improvement should be prioritized.
