SASHA Brief 2016: Expanded and Sustained Uptake of the Accelerated Breeding Scheme (ABS) Approach

The most important constraints to sweetpotato production in Sub-Saharan Africa (SSA) are shortage of high quality planting material and lack of improved OFSP varieties. The conventional breeding approach followed for decades by breeding programs starts with population development (generation of genetic variation through production of botanical seed) and ends with …

Presentation: Key Advances in Breeding Methodologies during Phase 1

This presentation outlines important advances in breeding methodologies to achieve ‘‘the better variety’’ that is variety with overall good traits. A major challenge in sweetpotato breeding is to achieve high heterozygosity for desired traits. Selection of parents for new population by considering Poly-cross Vs controlled crosses breeding are time consuming. …
