Genetic diversity of cassava (Manihot esculenta Crantz) landraces and cultivars from southern, eastern and central Africa por Kawuki, Robert S., Herselman, L., Labuschagne, Maryke T., Nzuki, I., Ralimanana, I., Bidiaka, M., Kanyange, M.C., Gashaka, G., Masumba, E., Mkamilo, G.S., Gethi, J., Wanjala, Bramwel W., Zacarias, A., Madabula, F., Ferguson, Morag E.

“…This is likely to reflect original germplasm introductions, gene flow including farmer exchanges, disease pandemics, past breeding programmes and the introduction of cultivars from the International Institute of Tropical Agriculture – Nigeria. Information generated from this study will be useful to justify and guide a regional cassava genetic resource conservation strategy, to identify gaps in cassava diversity in the region and to guide breeding strategies.…”
