| Innovation Title | Cassava population improvement through genomic selection |
| Innovation description | Traditional cassava breeding cycles using phenotype-based selection can take more than five years, limiting the rate of genetic gain and breeders’ ability to respond to new challenges. Shifting to genotype-based selection (Genomic Selection, GS) has the potential to overcome this limitation. Breeders can select superior clones using Genomic Estimated Breeding Values (GEBV) after only two years, which more than doubles the number of breeding cycles feasible. |

Stage reached
| Stage of Innovation | Stage 4: uptake by next user |
| Year (Stage) | 2020 |
| Stage Description | Released varieties have been handed over to seed systems partners for rapid multiplication and dissemination. Two early generation seed companies in Nigeria are partnering with the breeding program to ensure the production and commercialization of breeders and foundation seeds in a sustainable manner and to guarantee constant access. |
