An analysis of the bottlenecks affecting the production and deployment of maize seed in Eastern and Southern Africa AgEcon
Langyintuo, Augustine S.; Mwangi, Wilfred; Diallo, Alpha O.; MacRobert, John F.; Dixon, John; Banziger, Marianne.
The publication describes outcomes of a study conducted in 2007/08 to analyze the bottlenecks affecting the production and deployment of maize seed in eastern and southern Africa. The objectives of the study were to provide a better understanding of the factors limiting the production and deployment of improved maize seed in Africa, and to contribute to increasing the efficiency of variety release, seed production and seed dissemination for new drought tolerant maize varieties. The study identified a number of institutional bottlenecks affecting the maize seed value chain, in particular in the area of policy, credit availability, seed production, germplasm and marketing. To address these bottlenecks and improve the efficiency of seed production and...

An analysis of the challenges of the maize seed industry in eastern and southern Africa AgEcon
Langyintuo, Augustine S.; Mwangi, Wilfred; Diallo, Alpha O.; MacRobert, John F.; Dixon, John; Banziger, Marianne.
The liberalization and restructuring of the seed sector in eastern and southern Africa (ESA) during the past two decades have witnessed a proliferation of private seed companies in the maize seed industry (Hassan et al., 2001; Lemonius, 2005). Although the total number of registered maize seed companies increased from 8 and 11, respectively, in 1997 to 40 each, the quantities of seed marketed barely doubled, increasing from 23,000 and 27,000 tons to 53,000 and 51,000 tons, respectively; an indication that the reforms are insufficient in ensuring efficient functioning of the sector in the two regions. A study involving 117 seed providers, representing 92 percent of all registered maize seed companies in ESA in 2007 identified bottlenecks that have...

Breeding Quality Protein Maize (QPM): Protocols for Developing QPM Cultivars AgEcon
Vivek, B.S.; Krivanek, A.F.; Palacios-Rojas, N.; Twumasi-Afriyie, S.; Diallo, Alpha O..
This manual is intended for maize breeders who would like to start developing quality protein maize (QPM) cultivars. It is a compilation and consolidation of several breeding protocols successfully used at CIMMYT over two decades of QPM development and breeding. A brief background and the basic theory of QPM genetics are explained, leading up to detailed methods and procedures of QPM development.
