The high demand for good quality planting materials of improved cassava (Manihot esculenta Crantz) cultivars by the farmers in sub-Saharan Africa are not fully met in a timely manner. Perishability, slow multiplication rate and bulkiness of planting materials, weak definition of multiplication re...
Background Maize yield potential is rarely maximized in sub-Saharan Africa (SSA) due to the devastating effects of drought stress and Striga hermonthica parasitism. This study was conducted to determine the gains in grain yield and associated changes in an early-maturing yellow bi-parental maize ...
One suspected mutant with the broad, thick and dark green leaves characteristic of tetraploid cassava was found from each of the cassava clones TMS 91934 and TMS 89/00037-17 planted out in the field. Cytological examination confirmed them as tetraploids with chromosomes number 2n=4x=72. The mutan...
Cassava has long been expected to play a key role in rural economic growth in Africa, but has it happened yet? Although research partnerships have produced elite cassava varieties with 50% more yield potential and have demonstrated technologies to improve processing and increase marketing of cass...
Yam (Dioscorea spp.) is a major food of cultural, economic and nutritional importance in Nigeria and throughout West Africa. In this sub-region, white yam (Dioscorea rotundata) is the most dominant and important species. This study is aimed at characterizing high yielding yam varieties of this sp...
Accurate and timely detection is vital for mitigation of tuber yield losses resulting from yam mosaic virus (YMV) infection on yam, a major food security crop in West Africa. The observation, from our previous studies, that the triple antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA...
Greater yam (Dioscorea alata L.), belonging to the family Dioscoreaceae, is a staple food crop of the tropics. It is cultivated for its edible, nutritious, underground tubers. Its productivity declined due to anthracnose disease. There was no sequence information for yam in the public database. T...
