Identification and development of cassava brown streak disease resistant and early storage root bulking varieties in Malawi.
(2016)Cassava (Manihot esculenta Crantz) production in Malawi, like in most of the East African countries, has suffered from cassava brown streak disease (CBSD), a disease that affects both the quality and yield of storage roots. ... -
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. -
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 ... -
Introgression of aflatoxin and fumonisin contamination resistance genes in maize hybrids.
(2014)Maize is the principal crop in Africa, particularly in southern Africa. However, food security in the region is constantly threatened by the contamination of maize grain through mycotoxins, such as aflatoxins and fumonisins ... -
Investigation of growth potential of alternative eucalyptus species for mid and high altitude sites in the summer rainfall region in South Africa.
(2008)A study was undertaken to compare growth potential of three Eucalyptus species of natural origin in South Eastern Australia, with commercially grown species on mid and high altitude temperate sites in the summer rainfall ... -
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 ... -
An investigative study of the drought tolerance of F1 maize (Zea mays L.) single crosses derived from PANNAR and CIMMYT inbred lines.
(2015)Drought is the most devastating abiotic stress limiting the production of maize (Zea mays L.) worldwide. The effect of drought stress is greatest in sub-Saharan Africa (SSA) where most small scale farmers rely on open ... -
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 ... -
Morphological and cytological diversity of some yams (Dioscorea spp.) in Sierra Leone.
(2010)Yam (Dioscorea spp.) is a major source of income and a food security crop for many households in Sierra Leone. Despite the economic importance of the yam crop its improvement has suffered from the lack of knowledge of ... -
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 ... -
The mutagenesis of Sorghum bicolour (L.) Moench towards improved nutrition and agronomic performance.
(2009)In the breeding of grain sorghum (Sorghum bicolour L. Moench) towards improved nutrition and agronomic performance, new methodologies are required to increase genetic diversity and lower the inputs required to track and ... -
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 ... -
Path coefficient analysis and combining ability between quality protein and pro-vitamin - a maize lines for yield and secondary traits.
(2016)In most countries, white maize varieties are more preferred than the yellow/orange maize. Unfortunately, normal yellow and white maize lacks vitamin A which is crucial mainly for sight as well as growth and immunity. ... -
