Assessment of maize germplasm lines for genetic diversity, cultivar superiority and combining ability.
(2012)Maize (Zea mays L.) is an important crop in the world; however, its yield is compromised by new production challenges leading to poor yield in sub-Saharan Africa. This calls for a need to enhance maize adaptation to changing ... -
Breeding investigations for development of specialty green maize hybrids.
(2011)Green maize (Zea mays L.) provides food security and cash income to rural households in Sub-Saharan Africa (SSA). However, research on green maize varieties is scarcely reported in the literature. Consequently there is ... -
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, 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 ... -
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 ... -
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 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 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 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 ... -
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 ... -
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 ... -
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. ... -
Phenotypic and genotypic characterisation of F₄ families derived from a temperate X tropical maize population.
(2016)Abstract available in PDF file. -
Phenotypic characterization of mycotoxins resistant maize inbred families and regional hybrids under Aspergillus flavus and Fusarium verticillioides infestation.
(2015)Most South African households depend on maize as source of their staple food and daily calories intake, especially the rural communities which depend on the crop to maintain their livelihood. Despite the importance of ... -
Why SR52 is such a great maize hybrid.
(2013)Maize is Africa’s most important food crop. Unfortunately a yield gap currently exists in Africa which can be attributed to the use of inferior maize varieties such as open-pollinated varieties, double and three-way cross ...
