Genetic analysis of Maize Streak Virus (MSV) resistance in dwarf maize
(2012-08-29)Maize Streak Virus (MSV) is the most widespread biotic constraint to maize (Zea mays L.) production in Africa and may lead to total crop loss in susceptible varieties. Use of resistant cultivars is the most efficient and ... -
Genetic characterisation and analysis for yield and quality related traits in the Zimbabwean flue-cured tobacco germplasm
(Unpublished, 2020-05-30)Tobacco (Nicotiana tabaccum L.) is a crop with commercial value in most countries of the world and not much work has been done to improve its performance. Information on availability of genetic diversity expressible in ... -
Genetic characterisation of Striga gesnerioides and its control strategies in tobacco (Nicotiana tabacum L).

Genetic Diversity Assessment of Sorghum [Sorghum bicolor (L.) Moench] and Pearl Millet (Pennisetum glaucum L.) Landraces Collected from Zimbabwe’s Communal Areas, based on Microsatellites and Isozymes.
(2012-08-29)Landraces of sorghum [Sorghum bicolor (L.) Moench] and pearl millet (Pennisetum glaucum L.) are grown throughout Zimbabwe and frequently given names describing important traits they possess or their origin. Little ... -
Genetic Resource Base, Phenotypic Characters and Herd Dynamics of Indigenous Pigs in a Semi-arid Smallholder Farming Area of Zimbabwe
(2012-07-11)The objective of the study was to determine the genetic resource base, phenotypic characters and breeding systems of local pigs in Chirumanzu district, Zimbabwe. A survey, measurement of phenotypic traits of local pigs and ... -
Genetic variability, host specificity and resistance in Striga Asiatica-host plant interactions
(2012-08-30)Genetic analyses were conducted on Striga asiatica populations collected from different host species and geographic areas throughout Zimbabwe. These collections had been suspected to differ in their virulence, leading to ... -
Genomic selection in rubber tree (Hevea brasiliensis) using single nucleotide polymorphisms (SNPS) marker data obtained from genotyping by sequencing (GBS).
(2019-06-01)Genomic selection (GS) in rubber tree (Hevea brasiliensis) has huge potential to meet future demands of rubber in an economically and environmentally sustainable way. In Hevea breeding programmes, genomic selection can ... -
Genotype X Environment Interaction Effects on the Developmental Time, Kernel Modification and Yield of Experimental Quality Protein Maize (Zea mays L.) hybrid Varieties
(2012-08-30)Genotype „e environment interactions occur in crops grown in more than one environment such that it is unusual for a single genotype to perform better than other genotypes at all the locations in which they are grown posing ... -
Greenhouse gas emissions from cultivated dambos from Central Zimbabwe
(2016-04)Nitrous oxide (N2O), carbon dioxide (CO2) and methane (CH4) are potent greenhouse gases (GHGs) which cause climate change. The major anthropogenic sources of these GHGs are industrial production, burning of fossil fuel and ... -
Hardening, Population and Fertilizer Effects on Paprika (Capsicum annuum L.) Establishment and Yield in Chinyika Resettlement Area, Zimbabwe.
(2012-08-30)On–farm trials on paprika (Capsicum annuum L.) agronomy were carried out in Chinyika Resettlement Area during the 2000/1 to 2002/3 cropping seasons. The effect of nursery seedling density and hardening treatment on seedling ... -
“ Heterosis, Combining ability and Tester Identification of CIMMYT maize (Zea Mays L) adapted to low N conditions
(2012-08-30)The production of high yielding single cross maize testers with good combining ability and the potential to discriminate materials under evaluation across diverse environments, is important in breeding programs. Testers ... -
Identification of Fungal Seed Borne Pathogens in Farm Saved and Certified Seed of Sorghum (Sorghum Bicolor (L.) Moench) and Evaluation of the Incidence and Severity of Seed Borne and Non-seed Borne Disease in the Field.
(2012-08-30)A study to identify fungal seed borne pathogens on sorghum seed samples and to assess seed to field transmission of these pathogens was carried out at the Crop Science Department in the 2003/04 season. Seed samples collected ... -
Identification of molecular markers for screening tobacco germplasm resistant to white mould
(2016-06)White mould is a fungal disease of tobacco and other crops and is caused by Golovinomyces cichoracearum. White mould resistance is introduced into commercial varieties by backcrossing followed by phenotypic selection which ... -
Identification of soft rot species found in the Harare area of Zimbabwe and an evaluation of the susceptibility of selected potato cultivars of the pathogens
(2016)Experiments were conducted at the University of Zimbabwe, Crop Science Department from 2012- 2014 with the overall aim of identifying soft rot pathogens in the peri-urban Harare area and to screen some of the locally ... -
Impact of a goat pass-on scheme on goat management and productivity in Chipinge district
(2016-08)A goat production intervention was implemented in Musikavanhu communal lands Chipinge district by Action Contre La Faim (ACF). This was done by means of a pass-on scheme, where does were passed from one beneficiary to the ... -
Impact of Nematode pest management strategies on Nematode communities in tomato production systems in Zimbabwe
(2014-05-23)An analysis of soil nematode communities can be a useful tool for assessing the quality of soils and for the development of biological monitoring systems due to their intimate relationship of nematodes with their surrounding ... -
Improving maize (Zea mays L.) growth and yield using Jatropha (Jatropha curcas L.) seed cake under Zimbabwean soil condition
