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.
(2016)Maize (Zea mays L.) is the most important cereal crop in southern Africa. It is classified as a major staple food for human consumption. It is also used for animal feed in the livestock industry. Therefore, maize plays a ... -
Heterosis, genetic distance and path coefficient analysis in dent, flint and popcorn hybrids.
(2013)Maize (Zea mays L.) is one of the most important food crops in sub-Saharan Africa (SSA); however its production is constrained by many factors. Grain yield is compromised by poor genetic performance and poor agronomic ... -
Identification and development of cassava brown streak disease resistant and early storage root bulking varieties in Malawi.
(2016)Cassava (Manihot esculenta Crantz) production in Malawi, like in most of the East African countries, has suffered from cassava brown streak disease (CBSD), a disease that affects both the quality and yield of storage roots. ... -
Introgression of aflatoxin and fumonisin contamination resistance genes in maize hybrids.
(2014)Maize is the principal crop in Africa, particularly in southern Africa. However, food security in the region is constantly threatened by the contamination of maize grain through mycotoxins, such as aflatoxins and fumonisins ... -
Investigation of growth potential of alternative eucalyptus species for mid and high altitude sites in the summer rainfall region in South Africa.
(2008)A study was undertaken to compare growth potential of three Eucalyptus species of natural origin in South Eastern Australia, with commercially grown species on mid and high altitude temperate sites in the summer rainfall ... -
An investigative study of the drought tolerance of F1 maize (Zea mays L.) single crosses derived from PANNAR and CIMMYT inbred lines.
(2015)Drought is the most devastating abiotic stress limiting the production of maize (Zea mays L.) worldwide. The effect of drought stress is greatest in sub-Saharan Africa (SSA) where most small scale farmers rely on open ... -
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 ... -
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 ... -
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. ... -
