This involves the use of SSR and AFLP markers to tag quantitative trait loci for resistance to MSV, GLS and NCLB, and use SSR to study the diversity of maize gerplasm with respect to fungal disease resistance. SSR and AFLP markers were used to study recombinant inbred lines originating from two single crosses between two projenitor resistant inbred lines OSU 23i and CML 202, and one susceptible elite line EM 12-21 0 to generate mapping populations for identifying MSV resistance genes. A total of 19 MSV resistant lines were selected from cross EMI2-21O/OSU 23i using 7 polymorphic SSR primers and 23 lines from two crosses EM12-21010SU 23i and EMI2-210ICML 202 using 9 AFLP- primer-combination. The selected lines have been planted in Kiboko and Muguga sites for seed increase, line conversion and recombination. The project on the study of the diversity of genotypes with respect to fungal diseaseItem Kenya Agriculture Research institute Kiboko Research Centre(Kenya Agriculture Research institute, 2007) Kenya Agriculture Research instituteKARl is government parastatal charged with national responsibility of undertaking agricultural and livestock research on constraints that curtail production. The institute envisions a vibrant commercially oriented agricultural sector, propelled by innovative technologies, knowledge, and approaches that respond to demands and opportunities. The institute services its parent ministry (MOA) through provision of improved management techniques, better delivery systems of technologies, extension packages, and information and knowledge systems for improved agricultural development. This is done through research activities conducted at the institute's various Centres spread across the country, Kiboko being one of them.Item Poor Quality Techniques of Phosphine Fumigation in Kenya May Lead to Insect Resistance(Kenya Agriculture Research institute, 1994) Kenya Agriculture Research instituteI would like to express my thanks to Mr Gilbert Kibata, Chief Entomologist, Kenya Agricultural Research Institute, and his staff for assistance during this investigation, especially Mr Stephen Koech who accompanied me during all field visits. I wish also to express my thanks to Mr Osoro Umba, Pest and Quality Control Manager, and Mr Simon Muhihu, Operations Manager, both of the National Cereals and Produce Board, for information and invaluable assistance in enabling visits to be made to NCPB premises. Finally, the significant assistance provided by the many staff at NCPB stores, particularly those in pest control who readily gave information, is recognised, as is that from those in commercial servicing companies who were similarly cooperativeItem Preliminary Results Of A Socio-Economic Survey In Kibwezi, Oloitokitok And Wundanyi Divisions As Part Of The Larger Grain Borer Research Project(Kenya Agriculture Research institute, 1991) Kenya Agriculture Research instituteOne of the objectives of the Socio-economic component of the Larger Grain Borer Research Project (LGBRP) is to characterise the maize production, storage and marketing system in areas presently infested with the Larger Grain Borer (LGB) Prostephanus truncatus horn, and the impact of this insect upon these systems. To do this formal surveys were carried out in three Divisions: Kibwezi in Machakos District, Oloitokitok in Kajiado District, and Wundanyi in Taita-Taveta District.
