註釋Since collaborative research between Thailand and the CGIAR system was initiated in the early 1960s, many benefits have been derived at both the national and the farm level. Benefits to the National Agricultural Research System have been brought about by organizational changes, enhancement of researchers' capability, provision of genetic materials, and improvements in the methodology of research. All these have resulted in the speedier transfer of benefits to the farm level. It is estimated that the development of rice and corn varieties has benefitted at least 30 percent of all farm families. Research administrators and principal scientists have indicated high regard for this collaborative effort.
