Genetic study of cowpea (Vigna unguiculata (L.) Walp) resistance to Striga gesnerioides (Willd.) vatke in Burkina Faso.
(2010)In Burkina Faso, the existence of different races of Striga gesnerioides (Willd.) Vatke, with apparent variable aggressiveness on cowpea (Vigna unguiculata (L.) Walp) renders the breeding task very complex. Therefore, a ... -
Genetic, agro-morphological diversity and genome- wide association studies in sweetpotato (ipomoea batatas (L) lam.) accessions from Zimbabwe.
(2021)Abstract available in PDF. -
Improving resistance to Fusarium root rot [Fusarium solani (Mart.) Sacc. f. sp. phaseoli (Burkholder) W.C. Snyder & H.N. Hans] in common bean (Phaseolus vulgaris L.)
(2008)Fusarium root rot (FRR) disease, caused by the fungus Fusarium solani f. sp. phaseoli (FSP), is an important soil-borne disease reducing common bean (Phaseolus vulgaris L.) yields, and hence food security, in Uganda and ... -
Increasing the resilience of elite rice cultivars to sheath rot (Sarocladium oryzae [(Sawada) W. Gams & D. Hawksw]) in Rwanda through breeding for resistance.
(2016)Abstract available in PDF file. -
Inheritance of post-harvest pest resistance and genetic analysis of combining drought, maize lethal necrosis and maize weevil resistance in tropical maize germplasm.
(2020)Drought stress, maize lethal necrosis (MLN) and storage pests, mainly maize weevil (Sitophilus zeamais Motschulsky) and larger grain borer (Prostephanus truncatus Horn), are among the most important maize production ... -
Integrated Striga management in Sorghum through resistance breeding and biocontrol in the semi-arid regions of Tanzania.
(2017)Abstract available in PDF file. -
Integrating genetic resistance with biocontrol against rice blast and drought.
(2015)Annual demand for rice in Liberia far outstrips local production, mainly as a result of rice blast and drought. The use of resistant cultivars has been widely considered as the most economical means of controlling the ... -
Integrating sorghum [sorghum bicolor (L.) Moench) breeding and biological control using fusarium oxysporum against striga hermonthica in Ethiopia.
(2013)Sorghum [Sorghum bicolor (L.) Moench] is a major food security crop for millions of people in sub-Saharan Africa and the fourth most important crop in Africa. The potential sorghum yields are limited due to a number of ... -
Investigation of heterotic patterns and genetic analysis of Downy mildew resistance in Mozambican lowland maize (Zea mays L.) germplasm.
(2010)In Southern Africa and Mozambique, tropical lowland accounts for 22% and 65%, respectively, of area under maize production, but grain yield is compromised by downy mildew disease (DM, which is caused by Peronosclerospora ... -
Manipulating morphological traits of cassava to enhance host plant resistance and biological control of cassava green mite in Zambia.
(2013)Understanding direct and indirect defense mechanisms that enhance host plant resistance (HPR) and biological control is critical for successful development of an integrated pest management (IPM) approach. Cassava green ... -
Mutagenesis and development of herbicide resistance in sorghum for protection against Striga.
(2009)Sorghum (Sorghum bicolor) is an important cereal crop in sub-Saharan Africa. The parasitic weed Striga hermonthica is a major biotic constraint to sorghum production. A novel technology where planting seeds are coated with ... -
Occurrence of cowpea aphid-borne mosaic virus and prospects of improving resistance in local cowpea landraces in Uganda.
(2007)Viral diseases are a major limiting factor to cowpea production in many countries of Africa. In Uganda, studies indicated that the cowpea aphid-borne mosaic virus (CABMV) is common and a potential threat to cowpea ... -
Participatory cassava (Manihot esculenta Crantz) breeding for improved total carotenoids content and delayed postharvest physiological deterioration in Rwanda.
(2017)Abstract available in PDF file. -
Participatory-based development of early bulking cassava varieties for the semi-arid areas of Eastern Kenya.
(2006)Cassava (Manihot esculenta Crantz) is an important food security crop in the semi-arid areas of Eastern Kenya. It provides food for more days in a calendar year than any other crop grown. Kenya has relied on varieties ... -
Phenotypic characterisation and QTL mapping of adult plant resistance to leaf rust and stem rust of wheat (Triticum aestivum L.).
(2016)Abstract available in PDF file. -
Pre-breeding of Bambara groundnut (Vigna subterranea [L.] Verdc.)
(2014)Bambara groundnut (Vigna subterranea [L.] Verdc.) is an under-utilized indigenous African legume crop which has substantial potential to contribute to food security in sub-Saharan Africa. The crop is well adapted to severe ... -
Pre-breeding of tef [Eragrostic tef (Zucc.) trotter] for tolerance to aluminium toxicity.
(2015)Tef [Eragrostis tef (Zucc.) Trotter] is the most widely grown cereal crop in Ethiopia. Its grain is used for human consumption and the straw is an important and highly valued livestock feed. Soil acidity and Al toxicity ... -
Pre-breeding of wheat (Triticum aestivum L.) for Biomass allocation and drought tolerance.
(2018)Bread wheat (Triticum aestivum L., 2n=6x=42) is the third most important cereal crop globally after maize and rice. However, its production and productivity is affected by recurrent drought and declining soil fertility. ... -
