Genetic analyses for resistance to soybean rust (Phakopsora pachyrhiz) and yield stability among soybean genotypes in Kenya.
(2012)Soybean (Glycine max (L.) Merr.) occupies an important position in the world economy of the feedstock of high quality protein and vegetable oils. However, its production is threatened by, Asian soybean rust (ASR), caused ... -
Genetic analyses of drought tolerance and resistance to late blight among potato genotypes.
(2015)Potato is one of the valuable crops in Ethiopia serving as a source of food and income for smallholder farmers. About 70% of the country’s arable land is suitable for potato production. Despite the rapid growth of the total ... -
Genetic analysis and characterization of faba bean (vicia faba) for resistance to chocolate spot (Botrytis fabae) disease and yield in the Ethiopian highlands.
(2014)Faba bean (Vicia faba L.) is one of the most important food legumes cultivated in Ethiopia. However, its production has been limited by several factors, among which include chocolate spot (CS) disease caused by the fungus ... -
Genetic analysis and improvement of pearl millet for rust resistance and grain yield in Uganda.
(2014)Pearl millet is a sustainable food security crop for people living in areas with extreme drought and heat conditions. Like in many countries where it is grown, in Uganda the crop grows in semi-arid zones characterised by ... -
Genetic analysis and response to selection for resistance to two stem borers, Busseola fusca and Chilo partellus, in tropical maize germplasm.
(2014)Maize is the principal staple food in sub-Saharan Africa (SSA), but production lags behind population growth. The African stem borer, Busseola fusca, Fuller (Lepidoptera, Noctuidae), and the spotted stem borer, Chilo ... -
Genetic analysis and selection for maize weevil resistance in maize.
(2013)The maize weevil (Sitophilus zeamais Motschulsky) is one of the most destructive storage insect pest of maize (Zea mays L.) in tropical Africa and worldwide, especially when susceptible varieties are grown. Therefore, grain ... -
Genetic analysis for drought tolerance and yield stability in interspecific and oryza sativa L. rice germplasm.
(2015)Rice is currently an important staple food crop in Kenya. However, consumption continues to outstrip production. In spite of this, the country is endowed with untapped virgin land for rice production under rainfed upland ... -
Genetic analysis of common bean (Phaseolus vulgaris L.) genotypes for tolerance to drought and heat stress in Zambia.
(2015)Common bean (Phaseolus vulgaris L.) is widely grown and consumed in Zambia but its production is limited by drought and high temperature stresses. In the country there is limited information on farmers’ preferences and the ... -
Genetic analysis of drought tolerance in selected bread wheat (Triticum aestivum L.) genotypes.
(2016)Abstract available in PDF file. -
Genetic analysis of maize hybrids derived from temperate by tropical germplasm under low and high plant population density stress.
(2016)Maize is a major staple food crop in Sub-Saharan Africa and it plays a vital role in the livelihoods of small-scale and resource-limited farmers. The demand for maize is high and is also expected to increase due to the ... -
Genetic analysis of quantitative traits in soybean (Glycine max L. Merril) under low and high phosphorus conditions.
(2012)Soybean is emerging as a very important food, market and oil crop in Ethiopia. However, its productivity in Western Ethiopia is constrained by several production constraints, of which soil acidity is one of the most important ... -
Genetic analysis of Striga hermonthica resistance in Sorghum (Sorghum bicolor) genotypes in Eastern Uganda.
(2011)Sorghum (Sorghum bicolor) is the third most important cereal food crop in Uganda. However, the parasitic weed Striga hermonthica severely constraints its production. The use of Striga resistant sorghum varieties may be ... -
Genetic analysis of upland rice for grain yield and some agronomic traits under Striga hermonthica infestation in Uganda.
(2018)Abstract available in PDF file. -
Genetic analysis, combining ability and yield stability of maize genotypes under maize streak virus prone environments.
(2014)Maize (Zea mays L.) is one of the most important food security crops in Tanzania. It is annually cultivated in an area of 2 million hectares representing 45% of the total area allocated to crop production. However, maize ... -
Genetic and path coefficient analyses and heterotic orientation of maize germplasm under combined heat and drought stress in sub-tropical lowland environments.
(2016)Crop failures due to simultaneous occurrence of drought spells and heat waves have become a common phenomenon in tropical and subtropical environments as a consequence of climate change. This phenomenon has raised lots of ... -
Genetic diversity analysis of lowland sorghum [Sorghum bicolor (L.) Moench] landraces under moisture stress conditions and breeding for drought tolerance in North Eastern Ethiopia.
(2012)Sorghum [Sorghum bicolor (L.) Moench] is one of the most important cereal crops grown in arid and semi-arid regions of the world. The North Eastern regions of Ethiopia are known for its high sorghum production and genetic ... -
Genetic diversity and combining ability analyses of provitamin A maize (zea mays L.) inbred lines for drought stress tolerance.
(2018)Abstract available in pdf. -
Genetic diversity and combining ability of selected quality protein maize (QPM) inbred lines adapted to the highland agro-ecology of Ethiopia.
(2014)The high altitude sub-humid agro-ecology in Ethiopia is estimated to cover 20% of the land devoted to annual maize cultivation. More than 30% of small-scale farmers in this agro-ecology depend on maize production for ... -
Genetic diversity of proprietary inbred lines of sunflower, determined by mapped SSR markers and total protein analysis.
