Evaluation and identification of single-cross maize hybrids for use in tester development.
(2018)Development of testers from new inbred lines that are high yielding and high discriminating abilities in diverse environments, and in stress conditions is very important in maize breeding in southern and eastern Africa. ... -
Evaluation of advanced sorghum lines for use as possible parents in breeding for bio-ethanol production.
(2017)Abstract available in PDF file. -
Evaluation of early maturing maize (zea mays L.) hybrids for multiple-stress tolerance.
(2018)Maize (Zea mays L.) is the most important cereal in Africa, but a number of constraints including biotic, abiotic and socio-economic factors affect its production. The abiotic factors such as drought, low nitrogen (N) and ... -
Evaluation of maize hybrids for low-nitrogen stress tolerance, yield stability and genetic purity.
(2019)Nitrogen stress is among the major abiotic constraints that impede maize production in Africa. Therefore, development of maize varieties that are tolerant to low N stress conditions and stable across environments is needed. ... -
Evaluation of rice genotypes for grain yield and resistance to bacterial leaf blight (Xanthomonas oryzae pv.oryzae) disease.
(2018)Rice (Oryza sativa L.) is a staple food crop in many African countries including Tanzania. However, both regional and national rice production have failed to meet demand due to several constraints, among which is the ... -
Evaluation of selected free-living diazotrophic bacteria for plant growth promotion and biological control of damping-off fungi.
(2013)Inoculation with free-living diazotrophic bacteria is well documented to enhance vegetative growth and yield increases of various crops coupled with suppression of sublethal pathogens. The use of microbial inoculants has ... -
Evaluation of soybean [Glycine max (L.) Merrill] genotypes for grain yield and associated agronomic traits under low and high phosphorus environments.
(2018)Phosphorus is an important element for growth, development and seed formation in soybean and other plant species. This element is less available for plants. The capacity of absorbing phosphorus in the soil varies from one ... -
Evaluation of the performance of groundnut genotypes and their resistance to groundnut rosette virus.
(2017)The groundnut or peanut is one of the important legume crops of tropical and semi-arid tropical countries, where it provides a major source of edible oil and vegetable protein. The crop is mainly grown by smallholder farmers ... -
Farmer perceptions and genetic studies of rosette disease in groundnut (Arachis hypogaea L.) in northern Mozambique.
(2011)Groundnut (Arachis hypogaea L.) is an important food and cash crop in Mozambique and production has been constrained by lack of high-yielding cultivars and disease infection. Objectives of this study were: 1) to identify ... -
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 groundnut (Arachis hypgaea L.) for drought tolerance and seed yield in Malawi.
(2018)Groundnut (Arachis hypogaea L,) is one of the major sources of food and income for smallholder farmers in Malawi. It is a valuable food security crop that supplies fats and proteins to the predominantly maize–based Malawian ... -
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 agronomic and quality traits in popcorn hybrids.
(2012)Popcorn is increasingly becoming popular as a snack and is consumed widely all over the world. It is a high value crop, with possible multiplier effects like income generation for the under-resourced communities in the ... -
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 ...
