Breeding programs involve large investments of time and money, but can pay very large returns on investment in the form of improved varieties that benefit farmers, societies and the environment. International breeding efforts involving multiple partners and targeting regionally important constrai...

Procedures for the evaluation of sweetpotato trials. Manual.
A major objective of breeding at the Sweetpotato Support Platform for West Africa in Ghana, is the development of non-sweet cultivars suitable for use as staple foods, or in fried and other processed products. This priority was set during stakeholder consultations when establishing the program, a...

Potato and sweetpotato in Africa: transforming the value chains for food and nutrition security.
Sweetpotato breeding requires at least 5 years to obtain an advanced breeding clone for further testing with the goal of cultivar release. An accelerated breeding scheme (ABS) can be feasible if the genotype × year interaction is low. The objectives of the present study were to describe an ABS fo...

Release of orange-fleshed sweetpotato (Ipomoea batatas [l.] Lam.) cultivars in Mozambique through an accelerated breeding scheme.
The current study was aimed at identifying mega‐environments in Ghana and evaluating adaptability of superior sweetpotato [Ipomoea batatas (L.) Lam.] genotypes from a targeted breeding effort. Three sets of genotypes were evaluated in multi‐environment trials (MET). Twelve sweetpotato varieties w...
