Genetic Diversity among Disease Resistant Coffee Varieties and Cultivars in Rwanda Based On RAPD and SSR Markers
(University of Nairobi, 2013)Understanding the genetic diversity existing in a germplasm collection is important to identify parental combinations with distinct gene sets that can be used in crossing to obtain superior hybrids. This study was carried ... -
Genetic diversity and differentiation of Ankole cattle populations in Uganda inferred from microsatellite data
(University of Nairobi.Department of Animal Production, 2011)A total of 304 individuals from eight Ankole cattle populations of Uganda were analysed based on 19 microsatellite markers to investigate genetic diversity, relationships and population structure. Across all loci, 200 ... -
Genetic diversity and phylogeography of cassava mosaic viruses in Kenya
(Department of plant Science and crop protection, University of Nairobi, 2006)Cassava is a major factor in food security across sub-Saharan Africa. However, the crop is susceptible to losses due to biotic stresses, in particular to viruses of the genus Begomovirus (family Geminiviridae) that cause ... -
Genetic diversity and relationship of indigenous goats of Sub-saharan Africa using microsatellite DNA markers.
(2009)Sub-Saharan African goats with an estimated population of 180 millions are major asset for farmer communities in a range of agro-ecological zones. This study was undertaken to determine the genetic diversity in ... -
Genetic Diversity and Relationships of Indigenous Kenyan Camel (Camelus dromedarius) Populations: implications for their Classification
(2003)The genetic diversity and relationships amongst the dromedary (Camelus dromedarius) populations are poorly documented. Four recognized Kenyan dromedary breeds (Somali, Turkana, Rendille, Gabbra) and dromedary from Pakistan ... -
Genetic diversity and symbiotic efficiency of legume nodulating bacteria from different land use systems in Taita Taveta, Kenya
(Jomo Kenyatta University of Agriculture and Technology,United States International UniversityDepartment of Land Resource Management and Agricultural Technologies,University of Nairobi and World Agroforestry Centre (ICRAF)Kenya Forestry Research Institute, 2011)Populations of Legume Nodulating Bacteria (LNB) were assessed under glasshouse conditions from soils collected in Taita Taveta district, Kenya from various landuse systems. The populations were estimated by the ... -

Genetic diversity of African sorghum ('Sorghum bicolor' L. Moench) accessions based on microsatellite markers
(2014)Genetic diversity plays an important role in selection of parental stocks in plant breeding. Sorghum [Sorghum bicolor (L.) Moench] breeding initiatives have been constrained by lack of information on genetic diversity of ... -
Genetic diversity of Kenyan potato germplasm revealed by simple sequence repeat markers
(Faculty of Agriculture, 2011-10)International potato germplasm (Solanum tuberosum L.) has been long introduced to and bred in Kenya and the accumulated Kenyan Solanum germplasm is unique in its geographical and climatic ranges of adaptation to tropical ... -
Genetic diversity of Kenyan sorghum germ-plasm: Molecular diversity of Kenyan sorghum Germplasm using simple sequence repeats
(LAP LAMBERT Academic PublishingDepartment of Plant Science and Crop Protection, University of Nairobi, 2012-01)Sorghum bicolor (L) Moench is the fifth most important cereal crop globally and in Africa, it is the second most important after Maize. In Kenya , Sorghum is an important food security crop mainly cultivated in semi-arid ... -
Genetic Diversity of Phaeoisariopsis griseola in Kenya as Revealed by AFLP and Group-specific Primers
(Department of Plant Science and Crop Protection, 2004)Genetic diversity of 50 Phaeoisariopsis griseola isolates collected from different agroecological zones in Kenya was studied using group-specific primers and amplified fragment length polymorphism (AFLP) markers. Group-specific ... -
The genetic diversity of Rhizobium leguminosarum bv. viciae in cultivated soils of the eastern Canadian prairie
(Department of Plant Science and Crop Protection, 2006-01)Soil populations of Rhizobium leguminosarum bv. viciae (Rlv) that are infective and symbiotically effective on pea (Pisum sativum L.) have recently been shown to be quite widespread in agricultural soils of the eastern ... -
Genetic diversity of two selected antigen loci in Babesia gibsoni Asian genotype obtained from Japan and Jeju island of South Korea
(2009)Previous reports have shown that the secreted antigen 1 of Babesia gibsoni (BgSA1) and the thrombospondin-related adhesive protein of B. gibsoni (BgTRAP) are promising diagnostic reagents and vaccine candidates. Therefore, ... -
Genetic Diversity Within African Tomato Using Next Generation Sequencing
(University of Nairobi, 2018)Full potential of African tomato has not been tapped due to lack of information regarding its characterization. The aim of this work was to study the diversity of 17 African tomato landraces collected from Solanaceae gene ... -
