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 ...
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 ...
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 ...
Combining CBD Resistance with High Yields and Good Cup Quality: Success case in Ruiru 11 Cultivar
(2015)
Coffea arabica cv. Ruiru 11 is a composite of sixty six (66) F1 hybrid sibs each derived from a
cross between a specific female and male population. The pedigree of Ruiru 11 consist of CBD
resistance donors, Rume Sudan ...
Early Agronomic Performance of Some New and Existing Arabica Coffee Varieties in Kenya
(2015)
The primary goal of plant breeding is to improve yield, quality and disease resistance.
However, majority of reported work on coffee breeding primarily concerns agronomical
improvement that directly impinges on either ...
Coffee Breeding in Kenya: Achievements, Challenges and Current Focus
(2015)
Coffee production in Kenya is seriously constrained by two fungal diseases namely Coffee Berry Disease (CBD) caused by Colletotrichum kahawae (Waller & Bridge) and Coffee Leaf Rust (CLR) caused by Hemileia vastatrix (Berk. ...

(Asian Network for Scientific Information, 2012)
The objective of this study was to evaluate the effect of intra-row spacing on growth of French bean (Phaseolus vulgaris L.) in Maseno Division, Kenya. The study was carried out at Maseno University Horticultural Farm. ...
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 Characterization of Arabusta Coffee Hybrids and their Parental Genotypes using Molecular Markers
(2015)
Twenty coffee genotypes were characterized comprising of eleven F1 interspecific Arabusta hybrids,
three induced tetraploid Robusta parental genotypes, four Arabica parental genotypes, one diploid
Robusta accession and ...
Morphological Characterization of Five Newly Developed Lines of Arabica Coffee as Compared to Commercial Cultivars in Kenya
(ACADEMIC JOURNALS, 2010)
Five new lines of Arabica coffee and two existing commercial cultivars planted in the field were characterized morphologically. The objective of this study was to determine the level of morphological variation within and ...
