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 ...
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 ...
Inheritance of root dry matter content in sweet potato.
(African Crop Science Society, 2014)
There has been much emphasis on breeding for increased sweet potato storage root yield, but less on dry matter
yield, and its inheritance. High dry matter content (DMC) is associated with consumer preferences, and ...
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 ...
Performance and inheritance patterns of storage root yield traits in the new Kawogo X Beauregard sweet potato cross in Uganda
(Makerere University, 2017-05)
Performance and inheritance pattern of storage root yield related traits in the ‘New Kawogo’ x ‘Beauregard’ is crucial in genetic sweetpotato improvement in this population. This study was conducted to i) evaluate the ...
Determinants of participation of small holder farmers in marketing of grain amaranth: A case of Kamuli District, Uganda.
(Makerere University, 2014)
As a vegetable crop, grain amaranth plays an important role in improving household nutritional and economic status. Grain amaranth is still a new crop in Uganda's farming system, after being introduced by VEDCO in 2005 to ...
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 ...
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 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 ...
Genetic analysis of resistance to rice bacterial blight in Uganda
(African Crop Science Society, 2012)
Rice bacterial blight (Xanthomonas oryzae pv.oryzae) is a major constraint to rice (Oryza sativa L.) production in Uganda and as part of strategies to develop resistant cultivars, it is important to evaluate resistance of ...
