The spread of stem rust caused by Puccinia graminis f. sp. tritici, with Virulence on Sr31 in wheat in Eastern Africa
(American Phytopathological Society (APS), 2006)
Genetic diversity of African maize inbred lines revealed by SSR markers
(BioMed Central, 2007)
Knowledge of genetic diversity (GD) and relationships among maize inbred lines is indispensable in a breeding program. Our objectives were to (1) investigate the level of genetic diversity among maize inbred lines and (2) ...
Diagnostic research to enable adoption of transgenic crop varieties by smallholder farmers in Sub-Saharan Africa
(Academic Journals, 2003)
Diagnostic research is important in helping to create an enabling environment for promising biotechnology products in smallholder agriculture, before rather than after release. The biotechnology products that now hold ...
Factors influencing adoption of stress-tolerant maize hybrid (WH 502) in western Kenya
(Academic Journals, 2007)
Non-adoption of suitable maize varieties was identified as the second most important constraint responsible for low maize yields in western Kenya. In order to increase adoption of suitable varieties it is important to know ...
The maize seed system in Ethiopia: challenges and opportunities in drought prone areas
(Academic Journals, 2008)
This study examines how the performance of the maize seed system in Ethiopia affects small-scale farmers’ access to and use of improved maize varieties. Particular emphasis is given to the drought-prone agro-ecologies ...
Bt-transgenic maize does not deter oviposition by two important African cereal stem borers, Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae)
(FacT Limited, 2008)
Objective: To assess Chilo partellus Swinhoe (Lepidoptera: Crambidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae) ovipositional responses on Bt (Event 216, containing the Cry1Ab gene) and isogenic non-Bt (CML ...
Glutenin composition, quality characteristics, and agronomic attributes of durum wheat cultivars released in Ethiopia
(African Crop Science Society, 2002)
Eleven cultivars of durum wheat (Triticum durum L. var. durum Desf.) were evaluated across five environments in Ethiopia for grain yield, 1000 kernel weight, protein concentration, gluten strength, mixing time, mixing ...
Developing Bt maize for resource-poor farmers - Recent advances in the IRMA project
(Academic Journals, 2005)
This paper presents an overview of the advances in the IRMA project, which develops insect resistant maize varieties for resource-poor farmers, using both conventional breeding and genetic engineering. The project started ...
Estimation of optimum plot dimensions and replication number for wheat experimentation in Ethiopia
(African Crop Science Society, 2000)
Bread wheat was row and broadcast sown using uniform crop management practices on a research station soil classified as a haplic Nitisol, situated in a major wheat producing region of Ethiopia, during the 1996 and 1997 ...
Breeding and disseminating quality protein maize (QPM) for Africa
(Academic Journals, 2007)
Quality protein maize (QPM) describes a range of maize cultivars with twice the content of limiting amino acids lysine and tryptophan compared with conventional maize, and has been developed to help reduce human malnutrition ...
