Effect of yellow maize testers with varying resistance reactions on assessing combining ability of striga resistant maize inbred lines

Research Description

Classifying inbred lines following phenotypic evaluation can provide valuably great information in the selection of parental lines for the development of heterotic group and gives an opportunity to introgress a desirable genes from diverse sources into the available genetic base. The focus this study is to determine an appropriate tester for evaluation of the variability in combining ability of Striga resistant maize inbred lines. As parental selection based on combining ability has been used for exploitation of heterosis in maize, testers are successfully employed to assess the combining ability of inbred lines for selecting promising maize inbred lines for further testing in hybrid combinations.

Effect of sequential planting and harvesting of two cassava varieties on soil structure and chemical properties of southwestern Nigerian soils

Research Description

Cassava is more productive than most other crops when grown on infertile soils. However, the crop is very responsive to better soil fertility and may require high levels of fertilization to reach its yield potential. Objectives To evaluate the comparative advantage of fertilizer application on cassava yield and growth parameters at different planting and harvesting periods. To determine the effect of different planting and harvesting periods of two cassava varieties on soil structure and some chemical properties.

Safety of Open Sun dried and Solar tent dried plantain chips

Research Description

Plantain is a tropical fruit that constitute a staple food crop in Central and West Africa. It is a popular dietary staple due to its versatility and good nutritional value. Mature unripe plantain is usually processed into dried plantain chips by local producers using the natural sun drying which as some limitations. However, as a result of these problems, food safety is a major concern. Therefore, this research work is aimed to establish safety open sun dried and solar tent dried plantain chips through measurement of parameters that of safety concern. Also, the current practice of drying of plantain by local processors will be assessed. This research work will provide rational basis for drying plantain with affordable and sustainable local dryer to produce chips that are safe for consumption and can meet up with international standards for export.

Molecular Characterization and Heterosis of Extra-Early Maturing Pro-Vitamin A Maize Inbred Lines under Striga and Drought Stress Environments.

Research Description

I work on maize improvement and my research work deals with the development of maize hybrids that combine Striga resistance and drought tolerance with elevated levels of provitamin A carotenoids in the kernels. This breeding effort aims to firstly, address Striga infestation and recurrent drought which are major maize production constraints in the savanna belt of sub-Saharan Africa and secondly to mitigate vitamin A deficiency especially among infants in the sub-region.

Morphological and Molecular Characterization of Cowpea (Vigna unguiculata L. Walp) Land Races

Research Description

In this research, 157 accessions of cowpea have been used. This research seeks to evaluate the performance of some cowpea landraces for promising lines by characterization, using improved varieties as check. It also seeks to access the genetic diversity of the selected accessions using DArTseq SNP Markers. Twenty-six qualitative and twenty-four quantitative traits were measured using the International Board for Plant Genetic Resources (IBPGR) cowpea descriptors. This will help guide future international research in cowpea breeding especially in developing crosses with promising landraces and farmer preferred cowpea.

Mechanism of Resistance of Selected Cowpea Accessions to Bruchid, Callosobrochus maculatus to

Research Description

Cowpea is an economically important annual grain legume in Sub-Saharan Africa. West Africa is the centre of domestication due to the occurrence of the most primitive form and a wide genetic variation among the wild Vigna. Research has shown that Nigeria is the largest producer and consumer of cowpea in Africa however, the overall production is relatively low. Huge loss in the quality and quantity of cowpea has been attributed to infestation by insect pests and diseases. Cowpea bruchid (Callosobrochus maculatus), commonly called bean weevil is a field-to-store pest of cowpea and it is capable of causing a total loss in the quality of seeds by laying of whitish eggs which later on develop into adult weevils. Controlling of bruchids by treating the seeds with recommended insecticides on the field prior to storage has posed a threat to human life to the the toxic effect of its residue on the seeds. as a result, breeding of insect pest-resistant cowpea varieties has been adopted. Recently, a breakdown in the level of resistance has been observed in some accession that were previously screened and kept in the genebanks for further breeding. My PhD Study is to identify new sources of resistant genes to bruchids and also determine the nature of genes controlling inheritance to the insect pest.
