Role of silicon in mediating resistance towards rice blast in selected rice varieties
(Makerere University, 2022-07)
Rice blast caused by Magnaporthe grisea is one of the most serious diseases of rice, causing yield losses of 50 – 100% in susceptible varieties worldwide. Durable host resistance has been hard to achieve given large pathogen ...
Genetic study of cowpea resistance to flower bud thrips (Megalurothrips sjostedti Trybom)
Cowpea [Vigna unguiculata (L.) Walp.] is an important and cheap source of protein in the diets of poor people in developing countries. It is cultivated for its leaf and grain, with a grain yield potential of 3000 Kg ha-1. ...
Degeneration in quality of cassava planting material due to infection by cassava brown streak viruses
(Makerere University, 2018-12)
This study aimed at quantifying degeneration of cassava planting materials as a result of infection by CBSVs. Four cassava varieties (NASE 14, NASE 15, NAROCASS 1 and TME 204) were evaluated for their responses and ...
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 ...
Incidence and molecular variability of cassava brown streak disease in Rwanda
(Makerere University, 2018)
In Rwanda, despite the importance of cassava as staple food, its production is greatly limited by biotic and abiotic constrains leading to poor yields. One of the most important constraints to cassava production is the ...
Functional genetics in ascomycetes pseudocercospora fijiensis (synonym mycosphaerella fijiensis) the pathogen of black sigatoka disease in banana
(Makerere University, 2019-07)
Pseudocercospora fijiensis (P. fijiensis), causal agent of the black Sigatoka disease (BSD) on banana, has spread globally since its discovery in Fiji 1963 in all the banana and plantain growing areas across the globe. It ...
The role of metabolites in cassava (Manihot esculenta Crantz) resistance to Whitefly (Bemisia tabaci)
(Makerere University, 2019-04)
The whitefly (Bemisia tabaci) (Gennadias, 1889) is a major challenge in cassava production especially for most African regions. This is because most of the varieties used are susceptible to the pest resulting in severe ...
Resistance spectrum to anthracnose disease and the genetic effect of pyramided genes on yield in common bean
(Makerere Uniersity, 2019)
Bean anthracnose, caused by Colletotrichum lindemuthianum (Sacc. et. Magn) Lams. Scrib., is one of the most widespread and economically important fungal diseases of the common bean. The pathogen possesses a high genetic ...
Development of cassava brown streak disease among selected cassava genotypes as influenced by amount of starting inocula and level of host tolerance.
(Makerere University, 2014-07)
Cassava brown streak disease (CBSD) is a major threat to cassava production in Uganda and the coastal areas of eastern Africa. The disease is caused by two ipomovirus species; Cassava brown streak virus (CBSV) and Ugandan ...
Evaluation of cassava genotypes for resistance to cassava brown streak disease (cbsd) in Uganda.
(Makerere University, 2013-09)
Cassava (Manihot esculenta Cranz) production in Uganda is being constrained by the devastating effects of cassava brown streak disease (CBSD). CBSD is caused by cassava brown streak virus (CBSV), which affects all parts ...
