Forage diversity Grasses  90% of cultivated genera originated in sub Saharan Africa  Over 1000 species used as feed Forage legumes and other herbaceous plants  Most important legumes species originated in the Americas or the Mediterranean regions  Food feed crops – Cowpea, Lablab are African Fodder shrubs and trees  Most commonly grown originated in Central America and sub Saharan Africa  Problems of anti-nutritional factors
Purpose of CIAT tropical forage collection to make tropical forage options available to small-holder farmers in lowland tropics as ground cover against drought as living fence against flooding

Activities to support forage use in ILRI • Diversity in Napier grass – Phenotyping for biomass under drought – Genotyping using SSRs • Diversity in Buffel grass • Phenotyping for biomass under drought and cold environments • Nutritional diversity – Improved diagnostics for forage diseases – Forage seed production of promising genotypes – Forage seed agribusiness development
Concluding remarks  the four genebanks keep large options in legumes unmatched elsewherer (tremendous assets in post CBD context, when N fertilizers are expensive)  the four genebanks do not distribute to the expected high levels  the distribution is regional and with a strong neighborhood effect  users have been shifting over time, with farmers and commercial sector gaining  purposes have shifted over time, with agronomy declining and breeding gaining  there is a need for another mindset in genebanks: not curators, but users!
