Sub-imbibed storage of recalcitrant seeds of four species.
(2007)The seeds of Trichilia dregeana, Trichilia emetica, Podocarpus henkelii and Syzygium cuminii display the characteristics typical of recalcitrant seeds. It is the phenomena of ongoing metabolic activity and desiccation ... -
A quantitative study on growth, basic wood density and pulp yield in a breeding population of Eucalyptus urophylla S.T. Blake, grown in KwaZulu-Natal.
(2008)The first objective of this study was to evaluate Eucalyptus urophylla S.T. Blake provenances in terms of their growth, basic wood density and pulp yield properties. The second objective was to determine the genetic and ... -
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 ... -
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 ... -
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 ... -
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 ... -
Screening sweetpotato (Ipomoea batatas L.) for drought tolerance and high β-carotene content in Mozambique.
(2011)Sweetpotato (Ipomoea batatas, L.) is one of the important sources of carbohydrates and economic income in Mozambique. As with most of the food crops in Mozambique, it is usually produced by small-scale farmers under ... -
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 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 ... -
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 ... -
Responses of ten soybean [ glycine max (L.) merrill] genotypes for yield and nodulation to trichoderma and silicon applications.
(2012)A study was conducted to determine the responses of 10 selected soybean (Glycine max L.) genotypes to potassium silicate (KSi) and Trichoderma harzianum (Eco-T®) applications. Preliminary studies involving two independent ... -
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 ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
An investigative study of the drought tolerance of F1 maize (Zea mays L.) single crosses derived from PANNAR and CIMMYT inbred lines.
