Bacterial leaf streak disease of rice: A silent constraint to rice production in Uganda
(RUFORUM, 2016-08)Bacterial leaf streak disease (BLS) caused by Xanthomonas oryzae pv oryzicola is one of the emergent biotic constraints to rice production in Africa. The disease, which can cause yield loss of up to 60% on susceptible ... -
Characterisation of lowland rice varieties for tolerance to iron toxicity in Uganda.
(Makerere University, 2010-08)Iron toxicity in flooded soils is attributed to high iron content in the soil, low soil pH, low soil fertility as well as accumulation of harmful organic acids and/or hydrogen sulphide. Effective measures to ameliorate ... -
Evaluation of the response of rice genotypes to bacterial leaf streak disease in Uganda
(Regional Universities Forum for Capacity Building in Agriculture, 2016-10)Destructive rice diseases like bacterial leaf streak (Xanthomonas oryzae pv. oryzicola) have been reported to be on the increase. In 2014, researchers in Uganda spotted signs typical of bacterial leaf streak disease (BLS) ... -
Genetic analysis of resistance to blast disease (Magnaporthe oryzae) among local resistant rice varieties in Uganda
(Makerere University, 2021-12)Rice blast caused by Magnaporthe oryzae is one of the most serious diseases that jeopardize rice production in Uganda. In fact, it causes up to 100% yield loss in severe cases. In order to overcome the effect of this ... -
Incidence of aflatoxins, heavy metals and pesticide residues contamination in imported and locally grown white rice in Uganda
(International Journal of Science and Research (IJSR), 2021-11)There is increased global interest in the safety of rice because rice is a staple food for half of the world’s population and its safety influences consumers’ health. This study aimed at assessing the levels of aflatoxins ... -
Inheritance of resistance to rice bacterial leaf blight
(2014-08-05)In order to design appropriate control strategies for a major disease of rice Uganda, the bacterial leaf blight (BLB) disease caused by Xanthomonas oryzae pv.oryzae on rice, this study was initiated to a) assess ... -
Inheritance of resistance to the stalk-eyed fly (diopsis longicornis) in rice in Uganda
(Makerere University, 2017-01)Rice is an important staple food for more than half of the world’s population. Globally, rice production is limited by abiotic and biotic factors. Of the insect pests attacking rice, the stalk-eyed fly is the most abundant. ... -
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 ... -
Phenotypic characterization and genotype by environment interaction of selected rice (Oryza sativa L.) genotypes for cold tolerance in Uganda
(Makerere University, 2021-02)Rice is adversely affected by cold stress and which is a common problem in the highland areas of central East Africa (Uganda, Rwanda, northeast Tanzania, and Kenya) and Madagascar. Cold stress is known to cause 26% to 80% ... -
Study of sources and inheritance of resistance to African rice gall midge (Orseolia oryzivora) in lowland rice in Uganda
(Makerere University, 2021-02)The African Rice Gall Midge (AfRGM), Orseolia oryzivora is one of the major insect pests in Africa including Uganda. Yield losses of up to 100% are attributed to the AfRGM in different rice growing regions especially in ... -
Tolerance to sality and its Inheritance in lowland rice in Uganda
(Makerere University, 2022-12)In Uganda, soil salinity contributes to one of the most serious ecological and environmental problems in most of irrigation schemes. Developing a tolerant rice genotype to salt is one of the solutions to the problem of ... -
Toxicological risk associated with consumption of rice sold in Uganda
(International Journal of Scientific Advances, 2021-11)Previous studies have reported the presence of aflatoxins (AFB1, AFB2, AFG1 and AFG2), heavy metals (As, Cd and Pb) and organochlorine pesticide residues (OCPs) in rice sold in Uganda. However, the potential health ...
