A review of the Amplified Fragment Length Polymorphism (AFLP) technique in genotyping and DNA fingerprinting studies
(Department of Plant Science and Crop Protection, University of Nairobi, 2008)Amplified fragment length polymorphism (AFLP) is a marker based on polymerase chain reaction amplification of restricted fragments ligated to synthetic adaptors and amplified using primers which carry selective nucleotides ... -
Evaluation of Antibiotic Metabolites from Actinomycete Isolates for the Control of Late Blight of Tomatoes under Greenhouse Conditions
(Department of Plant Science and Crop Protection, University of Nairobi, 2008)Antibiotic metabolites from two antagonistic actinomycete isolates coded 28P and CS35 were evaluated for the control of late blight of tomatoes in the greenhouse. Five concentrations namely; half strength, quarter strength, ... -
Distribution of Turcicum leaf blight of maize in Kenya and cultural variability of its causal agent, Exserohilum turcicum
(Department of Plant Science and Crop Protection, University of Nairobi, 2008)The causal agent of Turcicum leaf blight Exserohilum turcicum was isolated from infected maize samples collected during a survey in seven districts representing the main maize growing areas of Kenya. The cultural variability ... -
Infectious structures and response of maize plants to invasion by Exserohilum turcicum (Pass). in compatible and incompatible host pathogen systems.
(Department of Plant Science and Crop Protection, University of Nairobi, 2008)Objective: To study the differential response of corn leaves to invasion by Exserohilum turcicum comparing compatible and incompatible host-pathogen systems. Methodology and results: Maize leaves excised from 14 day-old ... -
The occurrence of Fusarium species and mycotoxins in Kenyan wheat
(Department of Plant Science and Crop Protection, University of Nairobi, 2008)presence of head blight-causing Fusarium species. Fungal contaminationwas determined by isolation on agar media, while mycotoxin analysis was by direct competitive enzyme-linked immunosorbent assay (ELISA). The wheat ... -
Suitability of Locally Available Substrates for Oyster Mushroom (Pleurotus ostreatus) Cultivation in Kenya
(Department of Plant Science and Crop Protection, University of Nairobi, 2009)This study aimed at evaluating the suitability of selected substrates for mushroom production. Ten different substrates namely water hyacinth ( Eichhornia crassipes ), maize cobs ( Zea mays ), coconut fibre ( Cocos nucifera ... -
Similarities in functional attributes and nutritional effects of magadi soda and bean debris-ash used incooking African traditional dishes
(Department of Plant Science and Crop Protection, 2011)Magadi soda and bean debris-ash have been used as condiments for a long time by various ethnic groups in East and Central Africa in cooking traditional dishes. The aim of the study was to investigate whether magadi soda ... -
Resistance and inheritance of common bacterial blight in yellow bean
(Department of Plant Science and Crop Protection, 2011)Common bean (Phaseolus vulgaris L.) is the most important food legume among the pulses. It is a cheap source of protein, especially in Sub-Saharan Africa. However, bean production is constrained by bacterial diseases, of ... -
Reaction of selected common bean genotypes to physiological races
(Department of Plant Science and Crop Protection, 2011)The wide pathogenic variability occurring in Phaeoisariopsis griseola, the causal agent of angular leaf spot of common bean (Phaseolus vulgaris L.), dictates that new sources of resistance be continuously identified. This ... -
Multiple disease resistance in snap bean genotypes in Kenya
(Department of Plant Science and Crop Protection, 2011)Snap bean (Phaseolus vulgaris L.) is an important export vegetable crop, produced mainly by small to medium scale farmers under various disease constraints. Disease resistant varieties can reduce reliance on fungicides, ... -
Inheritance of resistance to angular leaf spot in yellow beans
(Department of Crop Science, 2011)Angular leaf spot (Phaeoisariopsis griseola (Sacc) is an important disease of common bean (Phaseolus vulgaris L.) in most parts of Africa, causing yield losses of 40-80%. This study was carried out to determine the inheritance ... -
Inheritance of fusarium wilts (Fusarium oxysporum F. sp. phaseoli) resistance in climbing beans
(Department of Crop Science, 2010)Fusarium wilt, caused by Fusarium oxysporum F. sp. phaseoli caused growers to abandon the most popular climbing bean cultivar, Umubano (G2333) in Rwanda. The present objective was to determine the nature of inheritance of ... -
Genetic variation for tolerance to low soil nitrogen (N) in common beans (Phaseolus vulgaries L.)
(Department of Crop Science, 2003)Low soil nitrogen is an important biophysical constraint to common bean (Phaseolus vulgaris L.) production in East and Central Africa. An average of 660 kg N ha-1 has been lost during the last 30 years from about 200 million ... -
Genetic diversity, inter-gene pool introgression and nutritional quality of common beans (Phaseolus vulgaris L.) from Central Africa
(Department of Crop Science, 2010)The Great Lakes region of Central Africa is a major producer of common beans in Africa. The region is known for high population density and small average farm size. The common bean represents the most important legume ... -
Bean Improvement for Low Soil Fertility Adaptation in Eastern and Central Africa
(Department of Crop Science, 2007)Low soil fertility is one of the most important common bean (Phaseolus vulgaris L) productivity yield limiting factors in Eastern and Central Africa and cause substantial production losses. As a component of integrated ... -
Diversity of Fungal Species Associated with Peanuts in Storage and the Levels of Aflatoxins in Infected Samples
(Department of Plant Science and Crop Protection, University of Nairobi, 2004)The threat of aflatoxin contamination in food commodities and its association with health risks in both animals and humans continues to raise increasing concern over years. In this report, fungal species found in association ... -
Aspergillus species and Aflatoxin b1 in soil, maize grain and flour samples from semi-arid and humid regions of Kenya
(Department of Plant Science and Crop Protection, University of Nairobi, 2012)Recurrent outbreaks of Aflatoxin (AF) poisoning in maize continue to exacerbate the food security crisis in Sub-Saharan Africa. This study determined the distribution and contamination levels of Aspergillus spp. and Aflatoxin ... -
