Biochemical Composition Within Coffea arabica cv. Ruiru 11 and Its Relationship With Cup Quality
Gichimu, Bernard M.; Gichuru, E. K.; Mamati, George E.; Nyende, A.B. (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 ... -
Genetic diversity among commercial coffee varieties, advanced selections and museum collections in Kenya using molecular markers
Gichimu, Bernard M.; Kathurima, CW.; Kenji, GM.; Muhoho, SM.; Boulanger, R.; Gichuru, E. K. (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 ... -
Methods for early evaluation for resistance to bacterial blight of coffee
Gichimu, Benson M.; Cheserek, J. J; Gitonga, P. N.; Gichuru, E. K.; Ithiru, J. M. (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 ... -
Occurrence of Ck-1 gene conferring resistance to Coffee Berry Disease in Coffea arabica cv. Ruiru 11 and its parental genotypes
Gichimu, Bernard M.; Gichuru, E. K.; Mamati, George E.; Nyende, A.B. (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 ... -
Variation and Association of Cup Quality Attributes and Resistance to Coffee Berry Disease in Coffea Arabica L. Composite Cultivar, Ruiru 11
Gichimu, Bernard M.; Gichuru, E. K.; Mamati, George E.; Nyende, A.B. (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 ...
