Genetic diversity of pumpkin accessions in Kenya revealed using morphological characters, diversity index, CATPCA and factor analysis
(2018-02)Pumpkin is one of the most morphologically variable genera in the entire plant kingdom. In Kenya, its genetic diversity is undocumented and distribution is haphazard. An expedition was done in Kakamega and Nyeri regions ... -
Food and income provision influence production of pumpkins in Kakamega and Nyeri in Kenya
(2018)Pumpkin is an emerging important fruit-vegetable, although its potential remains unexploited in Kenya. This study aimed at enhancing conservation, preservation and production of naturalized pumpkins through characterisation ... -
Evaluation of endogenous phytocomponents and amino acids associated with direct somatic embryogenesis of coffee (Coffea arabica L.).
(Khalsa Publications, Punjab, India, 2018-03-01)Coffee is one of the most important crops cultivated in the world for use in beverages and confectionaries. Embryogenesis is a complex process that begins with a single cell and ends with the formation of mature embryos. ... -
Relationships of Selected Endogenous Factors Associated with Direct Somatic Embryogenesis of Coffee (Coffea arabica L.)
(2018-05-30)Coffee is one of the most important cash crops produced in the world with great economic returns to growers and national gross domestic product. Somatic embryogenesis is a morphogenetic processes leading to plantlet ... -
Determination of Factors Influencing Cultivation and Utilisation of Pumpkins Among Smallholders in Kakamega and Nyeri Counties, Kenya
(Taylor and Francis, 2019-06-27)Pumpkin is becoming an important fruit-vegetable, although its potential remains unexploited in Kenya. This study aimed at enhancing conservation, preservation and production of naturalized pumpkins through the cataloguing ... -
Coffea arabica cultivar Ruiru 11 sibs exhibit significant variation in plant regeneration through direct somatic embryogenesis.
(ISDS LLC, Japan, 2018)This experiment evaluated the response of 11 selected recalcitrant coffee ‘Ruiru 11’ sibs to plantlet regeneration through direct somatic embryogenesis. Third leaf pair explants from field-grown mother plants were ... -
Shelf-life of pumpkin-blended products, flour and fruit slices of different presentation formats
(Science Publishing Group, 2019-04-10)Pumpkin has high potential of generating income and overcoming food insecurity. Today’s consumer looks upon the food industry to provide healthy, attractive convenience products that remain wholesome for long. However, ... -
Marketability of value-added pumpkin (Cucurbita moschata Duch.) fruit in selected Kenyan markets.
(Science Publishing Group, 2019-03-19)Abstract Pumpkin (C. moschata Duch.) fruit is a highly nutritious horticultural crop with great potential for commercialization. However, in Kenya many households do not buy and utilize pumpkins regularly, leading to low ... -
Variation of micronutrients in pumpkin fruit varieties grown by smallholder farmers within Lake Victoria Basin.
(2013)Food shortage is a common occurrence in the developing countries. The shortage is emancipated in both low quantity and poor quality resulting in deficiency based diseases. The fact that pumpkins have an easy production ... -
Evaluation of micronutrients in seeds of Pumpkin varieties grown by smallholder farmers in the Lake Victoria Basin.
(2013-12)This study shows micronutrients malnutrition and its devastating effects taking toll of the world, affecting over two billion of its population. Measures have been put in place that includes supplementation, fortification ... -
Mechanisms and Sources of Resistance in Tropical Maize Inbred Lines to Chilo partellus Stem Borers
(2013)Developing maize with durable resistance to maize stem borers could be enhanced by identifying genotypes with different mechanisms of resistance and pyramiding the resistances into high yielding genotypes. This study was ... -
Responses of tropical maize landraces to Spotted stem borer damage in Kenya
(2013-03)The potential to manage insect pests using host-plant resistance exists, but has not been exploited adequately. The objective of this study was to determine the resistance of 75 tropical maize landraces ... -
Resistance to spotted stem borer in commercial maize hybrids and open pollinated varieties in Kenya. Contributions from the 3rd Africa-Wide Women and Young Professionals in Science Competitions.
(2014)ABSTRACT Lepidoptera stem borers are major maize insectpests estimated to be responsible for annual losses of around 15% in sub-Saharan Africa and 13.5% in Kenya. The spotted stem borer (Chilo partellus Swinhoe, ... -
Genetic Diversity Analysis in Tropical Maize Germplasm for Stem Borer and Storage Pest Resistance using Molecular Markers and Phenotypic traits
(2015)One hundred maize inbred lines and eighty four hybrids were characterized for resistance to maize stem borer and post-harvest insect pests. This was achieved using genetic distance and population structure based on simple ... -
Towards a Graph-Theoretic Approach to Hybrid Performance Prediction from Large-Scale Phenotypic Data.
(2015-09)High-throughput biological data analysis has received a large amount of interest in the last decade due to pioneering technologies that are able to automatically generate large-scale datasets by performing millions of ... -
Optimizing experimental procedures for quantitative evaluation of crop plant performance in high throughput phenotyping systems
(2015-01)Abstract Detailed and standardized protocols for plant cultivation in environmentally controlled conditions are an essential prerequisite to conduct reproducible experiments with precisely defined treatments. Setting up ... -
Targeted sequencing reveals largscale sequence polymorphism in maize candidate genes for biomass production and composition PLoS ONE 10(7)
(2015-07-07)Abstract A major goal of maize genomic research is to identify sequence polymorphisms responsible for phenotypic variation in traits of economic importance. Large-scale detection of sequence variation is critical for ... -
Phenomic prediction of maize hybrids.
(Elsevier Ireland Ltd, 2016-08)Phenomic experiments are carried out in large-scale plant phenotyping facilities that acquire a large number of pictures of hundreds of plants simultaneously. With the aid of automated image processing, the data are converted ... -
Genetic variation of growth dynamics in maize (Zea mays L.) revealed through automated non-invasive phenotyping.
(John Wiley & Sons Ltd, 2017)Hitherto, most quantitative trait loci of maize growth and biomass yield have been identified for a single time point, usually the final harvest stage. Through this approach cumulative effects are detected, without considering ... -
