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 ...
Mathematical Modelling of Thin Layer Drying Kinetics of Onion Slices Hot-air Convection, Infrared Radiation and Combined Infrared- Convection Drying
(AENSI Publisher, 2014)
Onion slices were dried in convection hot-air, infrared radiation and combined infraredconvection
hot air dryers. A systematic experimental design was applied to analyse
drying kinetics due to the effect of type of dryer, ...
Diallel analysis of Snap bean (Phaseolus vulgaris l.) varieties for important traits
(Academic Journals, 2010-08-04)
The breeding programmes of many crops use diallel analyses because of the genetic information they offer to breeders. Six morphological and agronomic traits of Snap bean (Phaseolus vulgaris L.) were studied to investigate ...
Genetic Diversity of Cassava Mutants, Hybrids and Landraces Using Simple Sequence Repeat Markers
(SCIENCEDOMAIN international, 2014-10-11)
Aims: Cassava (Manihot esculenta Crantz) is a crop with largely unexplored and unexplained potentially valuable genetic variability. The knowledge and understanding of the extent of genetic variation of cassava germplasm ...
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. ...
Comparison of a gas fired hot-air dryer with an electrically heated hot-air dryer in terms of drying process, energy consumption and quality of dried onion slices
(Academic Journals, 2012-08-14)
Onion slices were dried in either a gas-fired hot air dryer or an electrically heated hot air dryer at air temperatures of 50, 60 or 70°C, and at air flow velocities of 0.5, 1.0 or 2.0 m/s. Records of the drying rates and ...
Alternative methods of harvesting and storage of grass biomass in a semi-arid region
(Academic Journals, 2012-04-12)
Biomass is considered a potential feedstock for many renewable energy production systems and interest especially in grass production has increased markedly in the last two decades. The present work focuses on grass biomass ...
Response of French Bean {Phaseolus vulgaris L.) to Intra-row Spacing in Maseno Division, Kenya
(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. ...
