A
boost for maize in the State of Mexico
The State of Mexico borders the country’s
capital, Mexico City—a potential market of nearly 20 million
inhabitants—but farmers there have struggled to make a profit
growing maize. CIMMYT is working to help them, as part of a new
partnership between the US Department of Agriculture (USDA) and
the Mexican Agriculture Secretariat (SAGARPA).
A mountainous entity in the geographical and cultural
center of Mexico, the State of Mexico occupies what many would consider
an envious position: it surrounds the country’s vibrant and
populous capital, Mexico City, whose 18 million-plus population
represents an attractive market for goods and services. Industries
dominate the state economy, but many inhabitants outside urban areas
practice farming, either to supplement their incomes or, in fewer
cases, as their chief livelihood. Most of the state’s farmers
have grown maize at one time or another, but few have made a profit
on the crop, despite their proximity to a megalopolis.
Years
of low prices, until recently, for maize grain have discouraged
farmers from investing in advanced practices or new varieties. “The
state of Mexico accounts for ten percent of national maize production,
but improved varieties occupy little more than a tenth of its maize
area,” says CIMMYT maize researcher Silverio García.
“And nearly all the maize they produce is white grained and
ideal for local foods, but fails to meet market standards for large-scale,
commercial tortilla production, feed or industrial uses.”
The state of maize
As part of a project launched in 2007 between the USDA and SAGARPA,
CIMMYT is working with counterparts in the State of Mexico to increase
the productivity and profitability of maize farming. Aims include
a broad characterization of maize varieties—both local and
improved—for traits of market value; breeding for market requirements;
farmer-participatory improvement and testing of varieties; and food
technology and nutrition research to guide the project and demonstrate
potential impact.
“The focus is on value-added blue, white, and
purple maize for food,” says CIMMYT maize breeder and project
leader, Gary Atlin. “But partly in response to declining supplies
and rising world prices of maize—driven at least in part by
the biofuels boom in the USA—farmers are increasingly interested
in yellow maize, and participants are developing and testing yellow
grain maize suited for feed and industrial markets.”
Atlin and Garcia recently led a workshop of 11 maize
scientists from the Mexican National Institute of Forestry, Agriculture,
and Livestock Research (INIFAP), Mexico State’s Institute
of Agriculture, Livestock, Water, and
Forestry Research and Training (ICAMEX), the Colegio de Postgraduados
(a graduate-level agricultural research and learning institution),
and CIMMYT to plan project activities. Participants contributed
detailed information on varieties grown in the state, agreed on
common software for managing and analyzing data from trials, and
discussed ways to foster farmer participation.
Efforts are building on prior work by CIMMYT in Mexico
to promote adoption of improved varieties in poorer regions, through
crossing local varieties and improved populations to improve farmer-identified
traits lacking in their varieties. CIMMYT has also worked with Mexican
breeders to develop improved, yellow-grain varieties for several
environments, including the Mexican highlands.
“We’re very excited about this project,”
says García. “Trials in 2008 will involve experimental
varieties that are crosses between improved and local materials,
pre-commercial varieties in 20 or more environments in the state,
and 40 on-farm demonstrations of commercially-available white and
yellow hybrids to get farmers’ feedback.”
