Response of improved cassava varieties in Uganda to cassava mosaic disease (CMD) and their inherent resistance mechanisms
(Academic Journals, 2011)Field based trials were setup to evaluate response and inherent resistance mechanisms to cassava mosaic disease (CMD) of four improved varieties; Nase 9, Nase 11, 00036 and 00057 together with Nase 4 and Bao as resistant ... -
Enhanced composting of rice straw through amendment with Tithonia Diversifolia and cattle manure
(Makerere University, 2014)The Government of Rwanda has promoted rice production increasing the acreage by 3000 ha in the last decade. This has increased the quantities of straws in the field, which the farmers mainly burning or used a hedge and ... -
Prevalence of sorghum anthracnose in different agroecologies of Uganda
(National Agricultural Research Organisation, 2013)Nine major sorghum growing agro-ecologies of Uganda were surveyed to establish the sorghum anthracnose incidence and severity. Hierarchical sampling was used. Severity of anthracnose in the field was rated on a scale of ... -
Reaction of rice cultivars to a virulent rice yellow mottle virus strain in Uganda
(African Crop Science Society, 2012)Rice (Oryza spp.) has long been an important food staple for many traditional rice growing communities. Key developments in efforts to improve rice production such as the development of NERICA varieties have been widely ... -
Distribution and biocontrol potential of phlD+ pseudomonads in corn and soybean fields
(The American Phytopathological Society, 2005)The abundance and diversity of phlD+ Pseudomonas spp. colonizing the rhizospheres of young, field-grown corn and soybean plants were assayed over a 3-year period. Populations of these bacteria were detected on the large ... -
Feasibilty of zein proteins, simple sequence repeats and phenotypic traits for background selection in quality protein maize breeding
(African Crop Science Society, 2011)Widespread adoption of quality protein maize (QPM), especially among tropical farming systems has been slow mainly due to the slow process of generating varieties with acceptable kernel quality and adaptability to different ... -
Efficacy of manual seed sorting methods in reduction of transmission of rice and cowpea seed-borne diseases
(African Crop Science Society, 2005)The production of rice and cow pea in Uganda is increasing in acreage rather than productivity. This is attributed to a number of factors, mainly seed-borne diseases. The farmers in Uganda mainly use farm saved seeds for ... -
Effect of crop protection management practice on yield of seven cowpea varieties in Uganda
(Taylor & Francis, 1996)Field experiments were conducted during the first and second rainy seasons of 1994 to evaluate the seed yield potential of two commonly grown cowpea varieties and five introduced lines under different pest and disease ... -
Influence of season and cropping system on occurrence of cowpea diseases in Uganda.
(American Phytopathological Society, 1997)An on-farm survey was conducted for two seasons (first and second rains of 1994) to determine influence of season and cropping systems on occurrence of cowpea (Vigna unguiculata) diseases in Uganda. Viral diseases were ... -
Reaction of waxy and opaque-2 inbreds and their derived progenies to multiple foliar diseases of maize in Uganda
(Canadian Center of Science and Education, 2012)Specialty maize lines possessing important endosperm genes waxy and/or opaque-2 enhance processing and nutritional qualities of the grain. However, production and utilization of specialty maize varieties for food, feeds ... -
Genetics of drought tolerance in common bean genotypes adapted to Ugandan conditions.
(Academic Journals, 2015)Common bean (Phaseolus vulgaris L.) is an important source of food and income for majority of households in Sub-Saharan Africa. However, bean production in Uganda is being affected by drought which has resulted from recent ... -
Development of intermittent drought stress tolerant common bean genotypes in Uganda
(African Crop Science Society, 2014)Common bean (Phaseolus vulgaris L.) varieties that are high yielding and drought-tolerant are crucial in coping with the effects of drought, that is prevalent among small scale producers living in Uganda. The objective of ... -
Prevalence of viruses infecting cowpea in Uganda and their molecular detection
(Academic Journals, 2012)The main areas for cowpea cultivation in Uganda were surveyed in June and October 2006 for viruses affecting the crop. Seed and leaf samples from symptomatic and asymptomatic plants were collected from farmers’ fields and ... -
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 ... -
