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. ... -
Pre-breeding sesame (Sesamum indicum L.) for improved yield, and oil quality and quantity in Ethiopia. Ukuzalanisa kwangaphambili i-Sesame (Sesamum indicum L.) ukuze kuvunwe u-oyela okuthuthukisiwe, oyikhwalithi nomningi e-Ethiopia.
(2022)ABSTRACT Pre-breeding Sesame (Sesamum indicum L.) for Improved Yield, and Oil Quality and Quantity in Ethiopia Sesame (Sesamum indicum L.; 2n = 2x = 26) is a multi-purpose industrial oilseed crop serving the food, ... -
Quantitative genetic analysis of agronomic and kernel endosperm traits in quality protein maize (QPM) and investigations of the putative nutritional value of contaminated QPM crops.
(2008)The importance of maize in sub-Saharan Africa and the potential of quality protein maize (QPM) to alleviate the nutritional gap caused by lack of access to adequate protein rich foods were highlighted. Frustrations from ... -
Recurrent selection for drought tolerance in Maize (Zea mays L. and study of heterotic patterns of maize populations from Eastern Kenya.
(2007)There are few maize varieties that are drought tolerant in semi-arid eastern Kenya and farmer perceptions of drought tolerant maize cultivars have not been studied in this region. Farmers in this region use maize landraces ... -
Recurrent selection for gray leaf spot (GLS) and phaeosphaeria leaf spot (PLS) resistance in four maize populations and heterotic classification of maize germplasm from western Kenya.
(2007)Maize (Zea mays L.) production is constrained by a number of stresses, amongst the most important are gray leaf spot (GLS) caused by a fungus Cercospora zeaemaydis Tehon and E.Y. Daniels and Phaeosphaeria leaf spot (PLS) ... -
Response to selection for downy mildew (Peronosclerospora sorghi) and maize streak virus resistance in three quality protein maize populations in Mozambique.
(2007)Quality protein maize (QPM) has high nutritional value, but production is threatened by downy mildew (DM) and maize streak virus disease (MSVD) among other constraints. There are few studies of DM and MSVD resistance in ... -
Studies of drought tolerance in interspecific progenies of Oryza glaberrima (Steud) and O. Sativa (L) and an appraisal of the use of male gametocides in rice hybridisation.
(2006)Rice production in Sub-Sahara Africa is hampered by drought stress, low farmer adoption of improved varieties, un-adapted germplasm, problems of crossability between species and problems of efficient emasculation. This ... -
Study of anthracnose (Colletotrichum lindemuthianum) resistance and its inheritance in Ugandan dry bean germplasm.
