Prevalence of viruses infecting cowpea in Uganda and their molecular detection

Amayo, R.; Arinaitwe, A.B.; Mukasa, S.B.; Tusiime, G.; Kyamanywa, S.; Rubaihayo, P.R.; Edema, R. (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 ...

Improvement of resistance to fusarium root rot through gene pyramiding in common bean

Obala, J.; Rubaihayo, P.R.; Gibson, P.; Edema, R.; Mukankusi, C. (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 ...

Inheritance of resistance to kernel infection by Aspergillusflavus and aflatoxin accumulation in groundnut

Ozimati, A.A.; Rubaihayo, P.R.; Gibson, P.; Edema, R.; Kayondo, I.S.; Ntare, B.R.; Okello, D.K. (International Scholars Journals, 2014)

Aflatoxin contamination in groundnut is one of the major barriers in international groundnut trade. Aflatoxin may cause human cancer, hepatitis and liver cirrhosis. The objectives of the study were to determine: (i) the ...

Genetics of resistance to groundnut rosette virus disease

Kayondo, S.I.; Rubaihayo, P.R.; Ntare, B.R.; Gibson, P.T.; Edema, R.; Ozimati, A.; Okello, D.K. (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 ...

A preliminary analysis of diversity among East African sweet potato landraces using morphological and simple sequence repeats (SSR) markers

Gichuru, V.; Aritua, V.; Lubega, G.W.; Edema, R.; Adipala, E.; Rubaihayo, P.R. (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, ...
