Abstract.- This
report documents the impacts of international maize breeding
research in eastern and southern Africa. It draws on information
from a comprehensive 1998/99 survey of public and private maize
breeding and seed production organizations active in the region. In
many countries of eastern and southern Africa, policy reforms
introduced in the 1980s and 1990s encouraged private sector
participation in the maize seed industry. The private sector now
supplies most of the maize seed in the region, spends more on
research, and generates a larger number of maize releases than the
public sector. Hybrids dominate varietal releases and seed sales, a
trend that may negatively affect subsistence-oriented farmers who
lack resources to buy fresh seed every season. Although farmers'
adoption of improved maize varies throughout the region, it has
increased steadily. Survey data show that CIMMYT's maize breeding
program has had significant impacts in eastern and southern Africa,
especially in recent years. Of the maize varieties released in the
region since 1990, 31% (55% if South Africa is excluded) were
developed using CIMMYT breeding materials. In 1996, more than 1.6
million hectares in eastern and southern Africa were planted to
varieties developed using CIMMYT germplasm. The varietal release
data and adoption data indicate growing demand for CIMMYT breeding
materials from both public and private breeding programs, as well as
growing acceptance by farmers of varieties developed using those
materials.
