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, ...
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 ...
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 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 ...
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 ...
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 ...
Genetic characterisation of Ugandan strains of Colletotrichum sublineolum using ISSR makers.
(National Agricultural Research Organisation, 2013)
Colletotrichum sublineolum, the causal agent of sorghum anthracnose, presents high variability, genetic instability and host specialisation, hence rapidly breaking down resistance. In Uganda, no population studies of ...
Influence of host plant resistance and disease pressure on spread of cassava brown streak disease in Uganda.
(SCIENCEDOMAIN International, 2015)
Cassava brown streak disease (CBSD) is a major constraint to cassava production in Uganda. The disease is caused by two ipomovirus species: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV), ...
Response of local cassava varieties in Uganda to cassava mosaic virus disease
(SCIENCEDOMAIN International, 2012)
Cassava mosaic disease (CMD) resistant varieties have been used to manage CMD in
Uganda. In spite the availability of a number of CMD resistant cultivars, several local
landraces are continually grown in Uganda because ...
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 ...
