Cassava community of practice (G7010.01.05, G4008.26)

The cassava community of pracitce (CoP) primarily aims to facilitate the routine application of marker-assisted selection (MAS) in breeding programmes and to develop relevant schemes that effectively integrates MAS with field-based strategies.

The CoP organises training and workshops for members, facilitates breeder-to-breeder visits and supports postgraduate students. Among other areas, CoP members have benefitted from workshops on data analysis of genotypic and phenotypic data through GCP’s support.
