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. ... -
Phenotypic and genotypic characterisation of F₄ families derived from a temperate X tropical maize population.
(2016)Abstract available in PDF file. -
Phenotypic and SSR-based characterization of new sources of Fusarium head blight resistance in wheat.
(2016)Wheat (Triticum spp.) is one of the most important cereal crops produced worldwide. South Africa is the largest wheat producer in sub-Saharan Africa (SSA). However, wheat production in South Africa is affected by many ... -
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. -
Phenotypic characterization of mycotoxins resistant maize inbred families and regional hybrids under Aspergillus flavus and Fusarium verticillioides infestation.
(2015)Most South African households depend on maize as source of their staple food and daily calories intake, especially the rural communities which depend on the crop to maintain their livelihood. Despite the importance of ... -
The physiology of germination and dormancy in seeds of gynandropsi gynandra L. Briq syn Cleome gynandra L. (Cleomaceae).
(2018)The “spider plant” Gynandropsis gynandra L. Briq,” is an important traditional leafy vegetable in many parts of Africa. The species is considered underutilized and has been mainly neglected by research systems. Yields are ... -
Pre-breeding of architectural traits related to direct harvesting in dry bean.
(2017)Dry bean (Phaseolus Vulgaris L.) is an important crop for direct human consumption worldwide. In South Africa, it is a major source of plant proteins and income among growers. The crop is mainly grown by commercial producers ... -
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. ... -
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 ... -
