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. ... -
Phenotypic and genotypic characterisation of F₄ families derived from a temperate X tropical maize population.
(2016)Abstract available in PDF file. -
Phenotypic and SSR-based characterization of new sources of Fusarium head blight resistance in wheat.
(2016)Wheat (Triticum spp.) is one of the most important cereal crops produced worldwide. South Africa is the largest wheat producer in sub-Saharan Africa (SSA). However, wheat production in South Africa is affected by many ... -
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 ... -
The physiology of germination and dormancy in seeds of Gynandropsi gynandra L. Briq syn Cleome gynandra L. (Cleomaceae).
(2018)The “spider plant” Gynandropsis gynandra L. Briq,” is an important traditional leafy vegetable in many parts of Africa. The species is considered underutilized and has been mainly neglected by research systems. Yields are ... -
Pre-breeding of architectural traits related to direct harvesting in dry bean.
(2017)Dry bean (Phaseolus Vulgaris L.) is an important crop for direct human consumption worldwide. In South Africa, it is a major source of plant proteins and income among growers. The crop is mainly grown by commercial producers ... -
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 ... -
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 ... -
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 ... -
