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, ...
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 ...
Comparing the yield components of three most popular commercial watermelon cultivars in Kenya with one newly introduced cultivar and one landrace
(Academic Journals, 2009-06)
High yield is a major goal for watermelon (Citrullus lanatus) breeders. The objective of this study was to compare the yield components of some watermelon accessions available in Kenya and to identify high yielding ...
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 ...
Yield of three Commercial Watermelon Cultivars in Kenya as compared to a local landrace
(2010)
High yield is a major goal for watermelon (Citrullus lanatus) breeders. The
objective of this study was to measure the yield potential of some watermelon
accessions available in Kenya and identify high yielding ones for ...
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 ...
