Legg, J.P.Whyte, J.Kapinga, R.Teri, J.Anderson, P.Morales, Francisco José[Management of the cassava mosaic disease pandemic in East Africa]Management of the cassava mosaic disease pandemic in East Africa

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...

Manual.]Procedures for the evaluation of sweetpotato trials. Manual.

African dry and starchy (DS) orange-fleshed sweetpotato [Ipomoea batatas (L.) Lam] (OFSP) cultivars, distinct from American moist or medium dry and sweet OFSP, have potential to fight vitamin A deficiency (VAD) in the world. This study assessed the genotype × environment (G × E) interactions in m...

In sub-Saharan Africa region, most sweetpotato are produced from diverse landraces that have constant turnover. The preference for high dry matter is between 28 to 35%. CIP breeding strategy for the past 15 years has been to collect, characterize, and conserve farmers' varieties; evaluate and dis...

Several cassava genotypes were observed although there were few bred varieties. The wide diversity in the cassava landraces was a consequence of the action of the farmers in continuously abandoning and introducing cultivars into their system as they tried to select those cultivars that met their ...

Cassava sweet potato intercropping experiments were carried out at Ukiriguru (semiarid zone), Tanzania during the period from 1989-91. Four cassava varieties used were, Msitu Zanzibar, Alpim valenca, Mzimbirala and Liongo control. The second experiment tested four cassava planting densities, 6666...

Sweetpotato is a major staple and co-staple root crop for millions of the rural people in Africa. Recently, it has been demonstrated to be of human health importance by combating vitamin A deficiency. This paper is a summary review of recent findings on the orange-fleshed sweetpotato (OFSP) farme...
