Yield stability of stem borer resistant maize hybrids evaluated in regional trials in east Africa
(Academic Journals, 2012)
Twenty-seven stem borer-resistant maize hybrids and three checks were evaluated in 14 locations in Kenya and Ethiopia to study the genotype x environment interaction (GEI) and yield stability. An analysis of variance was ...
Article
Revisiting the hetero-fertilization phenomenon in maize
(Public Library of Science, 2011)
Development of a seed DNA-based genotyping system for marker-assisted selection (MAS) has provided a novel opportunity for understanding aberrant reproductive phenomena such as hetero-fertilization (HF) by observing the ...
Article
Participatory farmer evaluation of stem borer tolerant maize varieties in three maize growing ecologies of Kenya
(Academic Journals, 2011)
Insect resistant maize for Africa (IRMA) project aims at developing and deploying insect resistant maize varieties to reduce grain losses due to insect pests. As part of incorporating farmers? perceptions to improve the ...
Article
Effects of insect population density and storage time on grain damage and weight loss in maize due to the maize weevil Sitophilus zeamais and the larger grain borer Prostephanus truncatus
(Academic Journals, 2011)
In the period 2007 to 2010, at localities Backi Maglic and Krivaja studies of weed seedbank were performed under soybean crop. Results showed that weed seed separated at Backi Maglic in all years dominated in the top soil ...

Performance of early maturing Katumani and Kito maize composites under drought at the seedling and flowering stages
(African Crop Science Society, 1998)
Two widely-used open pollinated maize (Zea mays L.) cultivars from East Africa, Katumani and Kito composites, developed and improved for early maturity, grain yield and drought escape were evaluated for drought tolerance ...

Comparative SNP and haplotype analysis reveals a higher genetic diversity and rapider LD decay in tropical than temperate germplasm in maize
(Public Library of Science, 2011)
Understanding of genetic diversity and linkage disequilibrium (LD) decay in diverse maize germplasm is fundamentally important for maize improvement. A total of 287 tropical and 160 temperate inbred lines were genotyped ...

Determination of levels of Striga germination Stimulants for maize gene bank accessions and elite inbred lines
(Gorgan University of Agricultural Sciences, 2012)
Parasitism by Striga hermonthica (Del) Benth is a severe constraint in maize production in sub-Saharan Africa. Varying levels of tolerance to Striga attack have been identified and exploited in breeding programs of several ...
Article
Adapting maize production to climate change in sub-Saharan Africa
(Springer Verlag, 2013)
Given the accumulating evidence of climate change in sub-Saharan Africa, there is an urgent need to develop more climate resilient maize systems. Adaptation strategies to climate change in maize systems in sub-Saharan ...

Adoption and continued use of improved maize seeds: Case study of Central Ethiopia
(Academic Journals, 2010)
The literature on agricultural technology is limited on the issue of the continued use of an agricultural technology after it is adopted. This paper analyzes the factors that explain adoption as well as continued use of ...

Marker assisted introgression of opaque2 gene into herbicide resistant elite maize inbred lines
(Academic Journals, 2006)
Marker assisted selection in combination with conventional breeding can greatly accelerate the introgression of modified opaque2 genotype into herbicide resistant maize. By combining these two approaches, time and costs ...
