Molecular markers are needed for enhancing the development of elite sweetpotato (Ipomoea batatas (L.) Lam) cultivars with a wide range of commercially important traits in sub-Saharan Africa. This study was conducted to estimate the heritability and determine trait correlations of storage root yie...

Sweet potato (Ipomoea batatas L.) was not an important crop in Ghana, Burkina Faso and Nigeria, West Africa, in the past decades. An effort has been made to reposition the sweet potato crop in West Africa. Orange-Fleshed Sweet potato (OFSP) cultivar was used as an entry point while properly desig...

Research to evaluate the potential of sweet potato to alleviate iron deficiency in affected human populations in developing countries is scarce. To partly fill this gap, we evaluated the bioaccessibility of iron in six sweet potato clones grown in two Peruvian environments, Satipo and San Ramon, ...

Studies were undertaken to investigate host relationships of populations of Bemisiu tubuci taken from the major crop hosts in Uganda. B. tubuci adults taken from cotton and sweet potato did not colonize cassava. None survived for longer than two days and nymphs emerging from eggs laid on cassava ...

Antenatal clinics (ANCs) are critical for improving maternal nutrition and health knowledge. The Mama SASHA project in western Kenya delivers an orange flesh sweet potato intervention through ANC to improve the vitamin A status of women and children less than 2 years. A nested cohort study follow...

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...

Sweetpotato is usually propagated in Uganda by vine cuttings from mature crops, but sometimes sprouts from storage roots are used, especially in drought-prone areas. No information is available on whether the storage of roots of Ugandan cultivars are infected with the viruses and whether the spro...
