The establishment of the Inter-Asian Corn Program in 1964, the Asian Regional Maize program in 1981, and the Tropical Asian Maize Network (TAMNET) in 1993, indicates the good cooperation within the corn industry in Asia which extends to other regions of the world. In addition to the above described results, another important benefit of this research and development (R & D) work has been that a number of graduate students have been involved and have thereby gained skills and experience which will enable them to increase maize productivity and production. conclusions The following observations on the success of corn research and development in Thailand have been cited by Chutkaew (1993): 1. It has depended in part upon cooperation through different agencies: USAI0, Rockefeller Foundation, CIMMYT, FAO and of visiting scientists. 2. Introduced germplasm has been of prime importance. 3. Appropriate germplasm and breeding procedures have been utilized. 4. COOperation among researchers in "Teamwork" has been important in R&D and testing materials developed over locations, seasons and years. 5. Through continued experiments, experience has been gained in analyzing and interpreting data, crucial in making progress in corn breeding. 6. There are capable successors to devote their efforts to continue ongoing research and initiate new projects to produce new varieties. 7. In view of the limitation of natural resources and other environmental problems, one area in which research should be conducted is in exploiting the marvelous corn plant even more so that full use can be made out of it.
