Characterisation of cowpea accessions based on agro-morphological traits, nutritional quality and molecular markers.
(2017)Abstract available in PDF file. -
Characterisation of selected bread wheat (Triticum aestivum L.) genotypes for drought tolerance based on SSR markers, morpho-physiological traits and drought indices.
(2018)Bread wheat (Triticum aestivum L.) and durum wheat (T. turgidum L. var. durum) are staple cereal food crops worldwide. In South Africa, bread wheat is the second most economically important cereal after maize. Drought ... -
Characterisation of sweet sorghum germplasm based on agro-morphological traits, molecular markers and juice related traits.
(2018)There is rising interest for alternative energy sources because of the decline in fossil fuel production and concern over environmental pollution. Currently most biofuel is based on maize and sugar cane as raw materials. ... -
Combining ability analysis of maize inbred lines and genotype x environment interaction of hybrids for grain yield and maize streak virus resistance.
(2018)Abstract available in PDF file. -
Combining ability and genotype-by-environment Interaction analyses among early-to-medium maturing maize hybrids under drought and non-drought environments.
(2021)Developing high yielding early to medium maturing maize hybrids for Southern Africa represents an effective way to contribute to improving crop productivity in the face of climate change and unpredictable weather patterns. ... -
Combining ability, genetic gains and path coefficient analyses of maize hybrids developed from maize streak virus and downey mildew resistant recombinant inbred lines.
(2015)Farmers in SSA continue to obtain low yields (less than two tonnes per hectare) despite the high potential yield (about 14 tonnes per hectare) that can be achieved. The development of improved and high yielding hybrids can ... -
Effect of insect pollinator species deployment and interactions with parental inbred lines in hybrid carrot seed production.
(2021)Insect pollinator species are highly valued for their contribution towards cross-pollination in many vegetable crops for food and seed production. Honeybees (Apis mellifera) are a significant main pollinator not only in ... -
Efficacy of mon 89034 bt trait in conferring fall armyworm resistance in high yielding three-way and single-cross maize hybrids.
(2020)Maize production, especially in tropical sub-Saharan Africa, is hampered by the fall armyworm (FAW) posing a serious threat to food security and livelihoods. Many methods of control including pesticide use have been tried ... -
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 soybean (Glycine max L. Merr.) lines for grain yield and drought-tolerance.
(2021)Soybean (Glycine max L. Merr.) is ranked as the fourth-highest commercial agronomic seed crop in South Africa. An increase in animal feed demand has mainly driven the significant growth in demand for soybean oilcake and ... -
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 ... -
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 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 maize streak virus disease resistance on tropical maize.
(2021)Maize streak virus (MSV) disease, transmitted by leafhoppers (Cicadulina mbila) is a major contributing factor to low maize yields in Africa. The disease threatens maize production in Zimbabwe, thus the importance of ... -
Genetic analysis of stem rust resistance among Ethiopian grown wheat lines.
(2014)Wheat (Triticum aestivum L.) is one of the major food crops in the world. Ethiopia is the second largest wheat producer in sub-Saharan Africa. However, wheat production in Ethiopia is constrained by many biotic and abiotic ...
