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 ... -
Genetic and economic value of a shuttle breeding programme for enhancing adaptability of tropical maize germplasm in South Africa.
(2013)Maize is the principal crop for food security and livestock feed in South Africa. It is also an industrial crop and the produce is exported to many countries in the world. Therefore there is high seed demand which prompts ... -
Genetic and environmental factors affecting rooting in Eucalyptus grandis X Eucalyptus longirostrata hybrid cuttings.
(2011)In clonal deployment programmes of plantation species, there is frequently the need to deploy Eucalyptus species and interspecific hybrids as rooted cuttings. However, the rooting ability of a particular species or hybrid ... -
Genetic characterization of pro-vitamin A and quality protein maize inbred lines and their derived hybrids.
Maize is one of the most important crop plant, valued both as cereal and forage crop because of high nutrition and palatability. Sub-Saharan Africa (SSA) countries are highly dependent on maize compared to other African ... -
Genetic variability, path coefficient and marker-trait association analysis for resistance to rosette disease in groundnut.
(2019-02)Several abiotic, biotic and socio-economic aspects constrain the production of groundnut (Arachis hypogea L.). Groundnut rosette disease (GRD) which can cause yield losses of up to 100% in susceptible cultivars, is among ... -
Genetic variation and associations among adaptive traits in a recombinant maize inbred line population.
(2012)Maize production in Africa is constrained by abiotic and biotic stresses. Breeders need to have information on the nature of combining ability of parents, their traits and performance in hybrid combination. This requires ... -
Genotypey by environment interaction, genetic variability and path analysis for grain yield in elite soybean [Glycine max (L.) Merrill] lines.
(2018)Soybean [Glycine max (L.) Merrill] is the world’s leading source of protein and vegetable oil. However, its productivity is still low in the region due to limited availability of stable and high yielding cultivars. Therefore, ... -
GGE-Biplot and genetic diversity analysis of maize hybrids and inbred lines from the breeding programme at UKZN.
