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.
(2006)The common bean (Phaseolus vulgaris L.) is an important crop grown widely in Uganda. It is also an important source of income for smallholder farmers particularly women. Despite its importance, production in the cool ... -
A study of heterotic grouping, gene action and genotype x environment interactions of mid-altitude and highland maize inbred lines in Rwanda.
(2016)Maize (Zea mays L.), is one of the staple crops in Rwanda that contributes to national economic growth. Furthermore, the genetic plasticity of maize permits its adaptation to a wide spectrum of environments ranging from ... -
Study of inheritance and identification of molecular markers for seed protein content in pigeonpea (Cajanus cajan (L.) Millsp.).
(2017)Abstract available in PDF file. -
A study of the diversity, adaptation and gene effects for blast resistance and yield traits in East African finger millet (Eleusine coracana (L.) Gaertn) landraces.
(2013)Finger millet (Eleusine coracana) productivity in East Africa has remained low in all production agro-ecologies for decades owing to the low yielding potential of existing that are susceptible to the blast disease caused ... -
Towards enhancement of B-carotene content of high dry mass sweetpotato genotypes in Zambia.
(2009)The enrichment of B-carotene, a precursor to vitamin A, in the local sweetpotato (Ipomoea batatas L.) cultivars is an attractive option in order to improve vitamin A intake in Zambia. The study was conducted to: 1) identify ...
