Background In spite of the essential role of cassava in ensuring household food security and employment for most rural farm households, postharvest physiological deterioration (PPD) of the roots which is serious abiotic stress in cassava renders the roots unmarketable, thereby reducing the economic value of the crop. This paper investigates farmers’ knowledge and perception of PPD in the storage roots...
Summary A participatory breeding programme involving farmers in two Ghanaian communities and scientists from CRI (Ghana) and NRI (UK) to develop superior cassava cultivars is described. Initial situation analyses of the communities indicated that cassava is increasing in importance both as a food and a cash crop. Most farmers utilised landraces of cassava; modern varieties were scarcely mentioned...
Summary The diversity of cassava was studied in 10 communities spanning a range of socio-economic circumstances and located in the four main agro-ecological zones in Ghana. On average, each farmer grew about two cultivars, mostly landraces, both for home consumption and sale of the storage roots. In total, 35 differently-named landraces were mentioned, 26 in only single communities. Most communities...
