Genotype-by-environment interaction of yam (Dioscorea species) for yam mosaic virus resistance, dry matter content and yield in Uganda
(MDPI, 2022-08-23)Often, yam cultivars grown in different agro-ecologies show differential responses across production environments, a term known as "genotype-by-environment interaction. Such genotype-by-environment interaction makes the ... -
Glucose performs better than fructose, sucrose, and diluted nectar for germination of banana pollen
(2020)Poor stigma receptivity is one of the limitations to seed set in East African Highland Bananas (EAHBs) that constrains their improvement through conventional breeding. This study aimed at identifying a suitable pollen ... -
The Horizon of Information Sharing at Makerere University: Multimedia, Audiovisual and the Linked Open Data
(Science Publishing Group, 2017-12-15)Makerere University has, in the recent past, climbed up the academic and research ranks, globally, and this has been supported by excellent information services, covering all available information resource formats and ... -
Incidence of aflatoxins, heavy metals and pesticide residues contamination in imported and locally grown white rice in Uganda
(International Journal of Science and Research (IJSR), 2021-11)There is increased global interest in the safety of rice because rice is a staple food for half of the world’s population and its safety influences consumers’ health. This study aimed at assessing the levels of aflatoxins ... -
Institutional Repositories Containing Digitized Heritage Material (Special Collections) are Making 'Lost or Hidden' Cultures Accessible: Advantages and Disadvantages of this Trend
(IOSR Journal Of Humanities And Social Science, 2017)The current information and electronic publishing age has tremendously increased the demand for academic institutions and libraries to recognise the importance of Institutional Repositories. They are essential infrastructures ... -
Nematode 18S rRNA gene is a reliable tool for environmental biosafety assessment of transgenic banana in confined field trials
(Springer, 2013-10)Abstract Information on relatedness in nematodes is commonly obtained by DNA sequencing of the ribosomal internal transcribed spacer region. How- ever, the level of diversity at this locus is often insufficient for ... -
Non-timber forest products markets: actors and income determinants
(2019-01)Trade in non-timber forest products (NTFP) is important in enhancing livelihoods of communities adjacent to forests. However, knowledge about actors and NTFP income determinants in Uganda is scanty. Yet this information ... -
Pathogenic variation of colletotrichum lindemuthianum causing anthracnose of beans (phaseolus vulgaris) in Uganda
(ESci Journals, 2016-01)Colletotrichum lindemuthianum is a highly variable pathogen of common beans that easily overcomes resistance in cultivars bred with single-gene resistance. To determine pathogenic variability of the pathogen in Uganda, ... -
Phenotypic diversity within Ugandan yam (Dioscorea species) germplasm collection
(Hindawi, 2022-12-19)A proper understanding of the diversity of the available germplasm is an initial step for the genetic improvement of a crop through breeding. However, there is limited information on the diversity of Uganda’s yam germplasm. ... -
Plant parasitic nematodes associated with banana and plantain in Eastern and Western Democratic Republic of Congo
(2013-01-20)Plant-parasitic nematode incidence, population densities and associated damage were determined from 153 smallholder banana and plantain gardens in Bas Congo (9 – 646 meters above sea level, m.a.s.l) and South Kivu ... -
Resistance to the weevils Cylas puncticollis and Cylas brunneus conferred by sweetpotato root surface compounds
(Journal of Agricultural and Food Chemistry, 2013-08-01)Seven resistant varieties of sweetpotato were compared with three susceptible varieties in field trials and laboratory bioassays and showed that resistance was an active process rather than an escape mechanism, as field ... -
Seed Set Patterns in East African Highland Cooking Bananas Are Dependent on Weather before, during and after Pollination
(MDPI, 2021-06-29)Seed set in banana is influenced by weather, yet the key weather attributes and the critical period of influence are unknown. We therefore investigated the influence of weather during floral development for a better ... -
Seed Set Patterns in East African Highland Cooking Bananas Show Asymmetric Distribution in Bunches and Fruits
(Agronomy, 2021-04-14)Low female fertility in bananas is the biggest hurdle for banana breeding. The aim of this study was to determine seed set patterns in East African Highland Cooking bananas (EAHBs) to inform future decisions on a more ... -
Silencing of the Mitogen-Activated Protein Kinases (MAPK) Fus3 and Slt2 in Pseudocercospora fijiensis reduces growth and virulence on host plants
(Frontiers in Plant Science, 2018-03-13)Pseudocercospora fijiensis, causal agent of the black Sigatoka disease (BSD) of Musa spp., has spread globally since its discovery in Fiji 1963 to all the banana and plantain growing areas across the globe. It is becoming ... -
Soil Organic Carbon Thresholds and Nitrogen Management in Tropical Agroecosystems: Concepts and Prospects
(Canadian Center of Science and Education, 2013)Soil organic carbon (SOC) is a potential soil fertility indicator for regulating nitrogen application in tropical farming systems. However, there are limited studies that have discussed SOC thresholds above or below which ... -
Sorghum (Sorghum bicolor) as a bean intercrop or rotation crop contributes to the survival of bean root rot pathogens and perpetuation of bean root rots
(Wiley, 2017-03-04)Root rots (RR) are the main cause of declining bean (Phaseolus vulgaris) production in southwestern Uganda. Here, beans are mainly intercropped/rotated with maize (Zea mays), sorghum (Sorghum bicolor), sweet potato (Ipomoea ... -
Toxicological risk associated with consumption of rice sold in Uganda
(International Journal of Scientific Advances, 2021-11)Previous studies have reported the presence of aflatoxins (AFB1, AFB2, AFG1 and AFG2), heavy metals (As, Cd and Pb) and organochlorine pesticide residues (OCPs) in rice sold in Uganda. However, the potential health ... -
Use of timelapse photography to determine flower opening time and pattern in banana (Musa spp.) for efficient hand pollination
(Scientific Reports, 2021)Sterility and low seed set in bananas is the main challenge to their conventional genetic improvement. The first step to seed set in a banana breeding program depends on pollination at the right time to ensure effective ...
