The role of Kenya in the trans-african spread of maize streak virus strain a
(Elsevier, 2017-03-15)Maize streak virus (MSV), the causal agent of maize streak disease (MSD), is the most important viral pathogen of Africa’s staple food crop, maize. Previous phylogeographic analyses have revealed that the most widely-distributed ... -
UGbS-Flex, a novel bioinformatics pipeline for imputation-free SNP discovery in polyploids without a reference genome: finger millet as a case study
(BioMed Central, 2018-12-01)Research on orphan crops is often hindered by a lack of genomic resources. With the advent of affordable sequencing technologies, genotyping an entire genome or, for large-genome species, a representative fraction of the ... -
Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 1. Morpho-physiological and biochemical responses
(CSIRO PUBLISHING, 2019-01-21)Iron (Fe) is a fundamental element involved in various plant metabolic processes. However, when Fe uptake is excessive, it becomes toxic to the plant and disrupts cellular homeostasis. The aim of this study was to determine ... -
Mechanistic understanding of iron toxicity tolerance in contrasting rice varieties from Africa: 2. Root oxidation ability and oxidative stress control
(CSIRO PUBLISHING, 2020-02-03)To enhance breeding efficiency for iron (Fe) toxicity tolerance and boost lowland rice production in sub-Saharan Africa, we have characterised the morphological, physiological and biochemical responses of contrasting rice ... -
Screening Of a Selected Tomato Varieties for Response to RalstoniasolanacearumINMASENO, Western Kenya
(Journal of Agriculture and Veterinary Science, 2020-06-08)Tomato (Solanumlycopersicum) is an important horticultural vegetable crop among small and large scale farmers in Kenya, grown for its nutritional and commercial purposes. However, gains from its production is limited by ... -
Finger millet
(Springer, Berlin, Heidelberg, 2006)Finger millet, Eleusine coracana Gaertn L., is a cereal grown for food in Africa and Southern Asia, mainly India (the states of Uttar Pradesh, Bilhar, Tamil Nadu, Karnataka, and Andhra Pradesh) and Nepal. In Africa, the ... -
The genetic map of finger millet, Eleusine coracana
(Springer-Verlag, 2007-01-01)Abstract Restriction fragment length polymorphism (RFLP), ampliWed fragment length polymorphism (AFLP), expressed-sequenced tag (EST), and simple sequence repeat (SSR) markers were used to generate a genetic map of the ... -
Comparative analyses reveal high levels of conserved colinearity between the finger millet and rice genomes
(Springer-Verlag, 2007-08-01)Finger millet is an allotetraploid (2n = 4x = 36) grass that belongs to the Chloridoideae subfamily. A comparative analysis has been carried out to determine the relationship of the finger millet genome with that of rice. ... -
Assessment of four commercial watermelon cultivars and one local landrace for their response to naturally occurring diseases pests and non-pathogenic disorders in sub-humid …
(Asian Research Publishing Network (ARPN), 2008)Four commercial watermelon cultivars available in Kenya and one local landrace were evaluated for their susceptibility/resistance to naturally occurring diseases, pests and non-pathogenic disorders. The accessions included ... -
Agronomic performance of three most popular commercial watermelon cultivars in Kenya as compared to one newly introduced cultivar and one local landrace grown on dystric …
(Asian Research Publishing Network (ARPN)., 2008)Agronomic performance trial involving five cultivated watermelon accessions available in Kenya was conducted at Maseno University Research Fields for two seasons between year 2007 and 2008. The accessions included three ... -
Responses of ecosystem carbon dioxide fluxes to soil moisture fluctuations in a moist Kenyan savanna
(Cambridge University Press, 2010-11-01)Measurements were conducted within a fence-exclosure between February 2008 and July 2009 to investigate the influence of soil moisture on ecosystem CO₂ fluxes in a Themeda triandra-dominated grassland of a humid Kenyan ... -
Carbon dioxide exchange and biomass productivity of the herbaceous layer of a managed tropical humid savanna ecosystem in western Kenya
(Oxford University Press, 2013-08-01)Aims Humid savannas, as a result of high precipitation amounts, are highly productive. They are also hotspots for land use change and potential sources of carbon dioxide (CO2) due to the large soil carbon (C) stocks. ... -
GOAT BREEDING IN LOW INPUT PRODUCTION SYSTEMS: INTERGRATING VALUES AND MODERN BREEDING TECHNOLOGIES FOR IMPROVING INSTRINSIC ROBUSTNESS
(2012-09)Low input production systems operate on long term values of supporting stable livestock production through efficient and sustainable combination of various production resources to achieve the desired production objectives. ... -
Genetic Relationship between Lactation Curve Traits in Dairy Cattle
(2010)Dairy cattle selection strategy in Kenya prefers cows with good 305-day lactation milk yield (TMY) in previous parity. This has improved milk production although increased incidences of physiological disorders and ... -
VARIANCE COMPONENTS AND GENETIC PARAMETER ESTIMATES UNDER VARYING DEFINITIONS OF CONTEMPORARY GROUPS
(KARI, 2010)A total of 19 385 test day (TD) milk yield records were used to determine the effect of contemporary group (CG) on estimates of variance components and genetic parameters for test day milk yield (TMY) data of Sahiwal ... -
NON-GENETIC SOURCES OF VARIATION IN LACTATION CURVE TRAITS OF DAIRY CATTLE IN KENYA
(2010)Lactation curves are a graphical representation of the milk production profile of a cow from parturition to drying up. They provide information about the productivity of the cow and offer a means of explaining features ... -
Genetic and non-genetic sources of variation in natural antibodies titre values among indigenous chicken
(American Journal of Research Communication, 2017)Innate immunity plays significant role in combating disease. Improvement of any trait including resistance to disease and infection requires identification of genetic and nongenetic sources of variation. This study aimed ... -
Genetic parameters for weaning weight of Kenyan Boran cattle accounting for direct-maternal genetic covariances
(South African Society for Animal Science, 2006)Genetic parameters were estimated for weaning weight (WW) in Kenya Boran cattle using animal models that assumed non-zero direct-maternal genetic covariance. In addition to the direct and maternal genetic effects, maternal ... -
