Morphological and genetic diversity analysis of rice accessions (Oryza sativa L.) differing in iron toxicity tolerance
(Korean Society of Crop Science and Springer, 2013)A major emphasis in breeding for iron toxicity tolerance in rice is to identify differences that are associated with resistance and harness them for genetic improvement. In this study, thirty accessions, including IRRI ... -
Combining ability for beta-carotene and important quantitative traits in a cassava F1 population
(Academic Journals, 2014)Cassava is ideal for biofortification due to its popularity as a root staple among populations with high vitamin A malnutrition. The crop is vegetatively propagated and retains the enhanced trait across generations. The ... -
Characterization and distribution of a Potyvirus associated with passion fruit woodiness disease in Uganda
(The American Phytopathological Society, 2012)This article describes the incidence and etiology of a viral disease of passion fruit in Uganda. Symptoms, including those characteristic of passion fruit woodiness disease (PWD), were observed on 32% of plants in producing ... -
Improvement of resistance to fusarium root rot through gene pyramiding in common bean
(African Crop Science Society, 2012)Fusarium root rot (FRR), caused by Fusarium solani f.sp. phaseoli, is one of the most serious root rot diseases of common bean (Phaseolus vulgaris L.) throughout the world. Yield losses of up to 84% have been attributed ... -
Combining ability of maize inbred lines for performance under low nitrogen and drought stresses
(African Crop Science Society, 2011)Drought and infertile soils are increasingly the most important stresses affecting maize (Zea mays L.) and causing substantial yield losses in Sub-Saharan Africa. Varieties with improved water use efficiency and/or N would ... -
Pests and diseases on cowpea in Uganda: Experiences from a diagnostic survey.
(African Crop Science Society, 1999)diagnostic survey (DS) using a questionnaire covering 525 farm households was conducted in 1993/94 to determine the status of cowpea (Vigna unguiculata L. Walp) and its production constraints in Uganda. Subsequent on-farm ... -
Genetics of resistance to groundnut rosette virus disease
(African Crop Science Society, 2014)Groundnut Rosette Virus disease (GRD) has long been regarded a major limiting biotic constraint to groundnut production in Sub-Saharan Africa (SSA). The disease is caused by a complex of three viral components that interact ... -
Population diversity of rice bacterial leaf blight isolates in Uganda
(Pelagia Research Library, 2013)The deployment of resistant cultivars is the best option to control bacterial leaf blight (BLB) and requires an understanding of the pathogen diversity. BLB caused by Xanthomonas oryzae pv.oryzae is a destructive disease ... -
A preliminary analysis of diversity among East African sweet potato landraces using morphological and simple sequence repeats (SSR) markers
(International Society for Hoticultural Science, 2006)East Africa is known to have a wide range of sweet potato landraces and, therefore, is considered to be a secondary center of diversity. In this study, we assessed the diversity among sweet potato landraces from Kenya, ... -
Variability of grain-filling traits in early maturing CIMMYT tropical maize inbred lines
(Crop Science Society of America, 2014)Grain-filling rate (GFR), effective grain-filling duration (EGFD), and total grain-filling duration (TGFD) are important physiological traits of maize (Zea mays L.) grain yield (GY) formation. To devise effective breeding ... -
Exploiting grain-filling rate and effective grain-filling duration to improve grain yield of early-maturing maize
(Crop Science Society of America, 2013)Early-maturing maize (Zea mays L.) genotypes yield 15 to 30% less than late-maturing genotypes. One strategy for improving grain yield in the early-maturing group involves assessment of grain-filling traits as secondary ... -
A comparative analysis of conventional and marker-assisted selection methods in breeding maize streak virus resistance in maize.
(Crop Science Society of America, 2009)Reliable information regarding comparative advantage of marker-assisted selection (MAS) over conventional selection (CS) in breeding for maize streak virus (MSV) resistance in maize (Zea mays L.) is scarcely available. A ... -
Evaluation of rhizobial inoculants on the productivity of soybean varieties grown on an acidic soil in Rwanda
(Makerere University, 2014)Several high yielding soybean varieties have been introduced in Rwanda but yields have remained low and even declining especially in areas with acidic soils. Consequently a number of rhizobial inoculants were introduced ... -
Stability of Barley genotypes for earliness, yield and resistance to leaf scald disease in Ethiopia
(2014-12)Scald, caused by Rhynchosporium secalis (Oud) Davis, is the most widely distributed and destructive disease of barley (Hordeum vulgare) in Ethiopia. Developing genetic resistance in early maturing genotypes is a viable ... -
Resilience of forest trees to debarking by elephants in Rabongo Forest, Murchison Falls National Park - Uganda.
(Makerere University, 2014)The main purpose of the study was to ascertain tree stem abundance, composition, tree species diversity, elephant damage, and the resilience mechanisms employed by the damaged trees over the last 20 years since 1992. Data ... -
Genetic and serological analysis of foot and mouth disease viruses (FMDV) in selected domestic and wildlife populations in Kenya.
(2014)Foot-and-mouth disease (FMD), a highly infectious viral disease of domestic and wild cloven-hoofed animals is endemic in Kenya and in eastern Africa. FMD virus (FMDV) exists in seven serotypes (O, A, C, Asia 1, SAT 1, SAT ... -
Development of a pilot scale anaerobic and aerobic/anoxic sequencing batch reactors and a constructed wetland system to treat abattoir wastewater.
(Makerere University, 2014)Over the past 27 years, Kampala, the Capital City of Uganda has witnessed a very high rate of population growth, urbanization and industrialization. Due to these developments, most wetlands in the environs of Kampala, ... -
Association between socio-economic factors and micronutrient intake (Iron, Zinc and Vitamin A) among children aged 6-59 months in Uganda.
(Makerere University, 2014)Background: Three million and five hundred thousand children under five years old die each year as a result of malnutrition. Nearly 150 million children under the age of five in the developing world are under weight for ... -
