CIAT's genebank in Cali, Colombia, lists almost 68,000 accessions in Genesys. The vast majority are seed crops, mainly beans, but CIAT also has a mandate to conserve cassava and tropical forages, and those too are held in the genebank. Almost 2000 of the accessions are wild relatives. The CIAT bean collection is the world's largest and most diverse, with more than 44,000 accessions.

Since the collection started in 1978, CIAT has distributed more than 187,000 samples of 37,368 accession to recipients in 164 countries. Accessions are contributing to the breeding of more nutritious and more resilient varieties, not least by CIAT's own breeders.

Cassava is represented by 6592 accessions (883 of which are provided by 33 of the 98 wild relative species of Manihot) stored as microplants in tissue culture. This collection too is considered a global leader because of the number of accessions, their diversity and the geographic range they represent. More than 41,000 samples have been distributed to 69 countries, guaranteed free of the three major viruses thanks to the work of the germplasm health laboratory at CIAT. The laboratory also ensures that seeds of beans and tropical forages are free of pests and diseases.

The tropical forage collection is also a world leader, with more than 23,000 accessions of about 740 species. CIAT and ILRI created the Tropical Forages Database, an online version of an interactive selection tool that helps researchers, farmers and their advisers to find the most appropriate forages.

Safety duplicates of 84% of the bean accessions and 78% of the forages have been placed in the Svalbard Global Seed Vault.

PDCI:护照数据完整性指数
Genesys 会使用 PDCI 作为已发布护照数据的完整性指标。PDCI 使用基因库种质文档中存在或缺失的数据点,以便考虑其他数据点的存在或价值(van Hintum 等人,2011 年)例如,野生种质应具有定义明确的采集站点,但没有品种名称。PDCI 的范围从 0 到 10,其中最低分数 0 表示相当不完整的护照记录,而最高分数 10 则表示非常完整的护照记录。种质的任何类型,野生、地方品种、育种材料或现代变体,都可以达到 PDCI 的最高分。
