Assessment of Four Commercial Watermelon Cultivars and one Local Landrace for Their Response to Naturally Occurring Diseases Pests and Non-Pathogenic Disorders in Sub-Humid Tropical Conditions
(Asian Research Publishing Network (ARPN), 2008-09)Four commercial watermelon cultivars available in Kenya and one local landrace were evaluated for their susceptibility/resistance to naturally occurring diseases, pests and non-pathogenic disorders. The accessions included ... -
Effect of Different Watering Regimes on Agromorphology of Selected Coffee Genotypes
(SCIENCEDOMAIN international, 2014-01-27)Aims: The aim of this study was to determine the effect of different watering regimes on selected coffee genotypes and to evaluate drought tolerance among selected coffee genotypes. The study also aimed at determining ... -
Selection within Coffea arabica cv. Ruiru 11 for high cup quality
(Academic Journals, 2012-09-26)In recent years, consumer awareness about the quality of different coffees has increased and therefore production and supply of coffee with excellent quality attach more significance. As a result, many coffee producing ... -
Selection of Ruiru 11 hybrid sibs on raw coffee quality
(2012-06)The economic value of Arabica coffee (Coffea arabica L.) is determined mainly by the yield potential, the size and shape of raw beans and beverage quality. Bean quality reportedly differ depending on the variety, environmental ... -
Variation and Association of Cup Quality Attributes and Resistance to Coffee Berry Disease in Coffea Arabica L. Composite Cultivar, Ruiru 11
(2013-12)Majority of reported work on coffee breeding primarily concerns agronomic improvement that directly impinges on coffee quality. However, it is crucial that coffee breeding programmes for disease resistance also include ... -
Occurrence of Ck-1 gene conferring resistance to Coffee Berry Disease in Coffea arabica cv. Ruiru 11 and its parental genotypes
(Scienceweb Publishing, 2014-03)Resistance to Coffee Berry Disease (CBD) in Coffea arabica cv. Ruiru 11 is known to be controlled by among others, the T (Ck-1) gene from Robusta coffee (Coffea canephora Pierre). The cultivar reportedly presents significant ... -
Morphological characterization of Kenyan native wood ear mushroom [Auricularia auricula (L. ex Hook.) Underw.] and the effect of supplemented millet and sorghum grains in spawn production
(2011)Utilization of mushrooms collected from the wild requires adequate description of useful phenetic features and domestication protocols. This study investigated morphological characters and spawn production procedures of ... -
Growth and nutrient uptake among three wetland plant species occurring in Lake Victoria basin in Kenya.
(2010)Nutrient enrichment is one of the most serious threats to wetland ecosystems. Information is lacking, particularly concerning the response of wetland plants species in Kenya in regard to nutrient enrichment of wetlands. ... -
Genetic diversity among commercial coffee varieties, advanced selections and museum collections in Kenya using molecular markers
(Academic Journals, 2012-02)Molecular markers have effectively been applied to study genetic diversity and as markers of particular traits. This study assessed the diversity of twenty four (24) coffee genotypes using 10 Random Amplified Polymorphic ... -
Field Screening of Selected Coffea arabica L. Genotypes Against Coffee Leaf Rust
(2012-06)Coffee Leaf Rust (CLR) is a fungal disease caused by Hemileia vastatrix Berk et Br. and is one of the major diseases of coffee. It causes premature leaf fall, yield loss and even death of the tree in severe cases. Coffee ... -
Evaluation of beverage quality and green bean physical characteristics of selected Arabica coffee genotypes in Kenya
(Academic Journals, 2009-10)Physical characteristics of green coffee bean have been reported to affect beverage quality to some extent. The objective of this study was to assess the beverage quality and green bean physical characteristics of forty ... -
Early performance of five newly developed lines of Arabica Coffee under varying environment and spacing in Kenya
(2010)Knowledge of the effects of environment and genotype by environment (GxE) interaction is important to breeders in making decisions regarding the release of new cultivars. Five Coffea arabica lines coded CR8, CR22, CR23, ... -
Early Assessment of Growth and Yield Characters of five newly developed lines of Arabica Coffee in two environments and spacings in Kenya
(2010)Knowledge of the effects of environment and genotype by environment (GxE) interaction is important to breeders in making decisions regarding the release of new cultivars. Five Coffea arabica lines coded CR8, CR22, CR23, ... -
Drought and heat tolerance in coffee: a review
(2012-12)Climatic variability is the main factor responsible for the fluctuations in the coffee yield in the world. The relationships between the climatic parameters and the agricultural production are quite complex, because ... -
Morphological Characterization of Some Wild and Cultivated Watermelon (Citrullus Sp.) Accessions in Kenya
(2009-03)Genetic diversity and relatedness were assessed among three most common commercial watermelon cultivars in Kenya; one newly introduced commercial cultivar from the U.S., one Kenyan landrace and one wild (Citrullus colocynthis) ... -
Biochemical Composition Within Coffea arabica cv. Ruiru 11 and Its Relationship With Cup Quality
(Canadian Center of Science and Education, 2014-01-14)Biochemical composition appears to be influenced by both genetic factors and plant growth conditions. The main objective of this study was to evaluate the biochemical composition of selected Ruiru 11 sibs and its relationship ... -
Methods for early evaluation for resistance to bacterial blight of coffee
(Academic Journals, 2013)Bacterial Blight of Coffee (BBC) caused by Pseudomonas syringae pv garcae has become of major concern in Kenya due to its increasing incidence and severity. For decades, the disease was confined within and to the west of ... -
Metal Status of Nairobi Riverwaters and Their Bioaccumulation in Labeo Cylindricus
(Springer, 2005-03-03)This study focused on the analysis of metals in water and fish from Nairobi River. Water from Kikuyu, Kawangware, Chiromo, Eastleigh, Njiru and Fourteen Falls along the Nairobi River was analyzed for the presence of metals. ... -
Isolation, Characterization and Identification of Enterobacteriaceae from well water in Juja Town in Kenya
(2009)Water for docmestic use is increasingly becoming a scarce resource forcing communities to resort to underground water sources. However, increasing wells and boreholes are facing threats of pullution from sewage. Water ... -
