Pandey, S. (CIMMYT, Mexico, DF (Mexico). Advanced Unit)
The CIMMYT advanced unit develops maize populations using a superior fraction of materials from appropriate gene pools as well as other materials, and improves them through International Progeny Testing Trials. This document describes in detail the population improvement procedure followed at CIMMYT. As a result of selection the populations have been improved for most agronomic traits under varying environmental conditions. CIMMYT materials are extensively used by both national programs and the private sector. Approximately 125 releases have been made in 30 countries using CIMMYT materials. In 75 percent of country variety releases, the variety was developed on the basis of data from another country. Approximately 8 percent of the maize growing area in developing countries is planted to CIMMYT-derived varieties. Their contribution is estimated at 600,000 tons annually and worth 90 million dollars at current international maize prices
