Cowpea is a highly drought-adapted leguminous crop with great promise for improving agricultural sustainability and food security. Here, we report analyses derived from array-based genotyping of 2,021 accessions constituting a core subset of the world's largest cowpea collection, held at the International Institute of Tropical Agriculture (IITA) in Ibadan, Nigeria. We used this dataset to examine genetic variation and population structure in worldwide cowpea.

- Crop landraces are valuable for both their unique traits and contributions to plant breeding, leading to increased efforts to preserve them globally.
- A study assessed how well these landrace groups from various crops are represented in genebank collections, finding that about 63% of their distributions are preserved, though this varies by crop.
- Significant conservation gaps exist for certain crops and regions, particularly in South Asia, the Mediterranean, and sub-Saharan Africa, indicating opportunities for enhanced collection efforts to meet global conservation goals.
The international collections of plant genetic resources for food and agriculture (PGRFA) hosted by 11 CGIAR Centers are important components of the United Nations Food and Agriculture Organization's global system of conservation and use of PGRFA. They also play an important supportive role in realizing Target 2.5 of the Sustainable Development Goals.
