||Maize in Indonesia is the second important food crops with the annual harvested areas of 4.0 M ha with the total production 16.32 M ton (CBS, 2008). However, the country still imports maize to meet its increasing domestic demand, which mainly used for feed industry. The increase of maize production in the future will depend on the areas expansion particularly to outer islands of Java. Much of the potential areas for maize expansions in eastern parts of the country are characterized by dry land ecology which often facing drought problems. Therefore, generating a variety that tolerant to drought, early duration and high yield to support maize environment is one of the major activities at ICERI. Several maize that have been released had a genetic background from CIMMYT line, i.e. the OPV Lamuru (20% genetic background from CIMMYT lines), Sukmaraga and Anoman (the major genetic contribution were derived from CIMMYT line), and Srikandi Kuning and Putih (CIMMYT population), while ICERI was carried out in producing the population, and recombination and selection through multiple location trials in many site prior to be released). Similar works were done in two of our maize hybrids (Bima-2 and Bima 3), the male parents were also genetically derived from CIMMYT line in Mexico and CIMMYT Thailand. CIMMYT has tremendous impact on maize development in Indonesia, through the collaboration of research activities and capacity buildings, i.e.
