The success of hybrids is evident by the area planted and by the rapid yield increase for the last 5 years.|In order to support the Maize Breeding Program, since 1971 we started to collect locally available gennplasm, and to import maize germplasm from various ecological zones. From 1973 -1993, the OPV Breeding Program was given top priority, and seven OPVs were released for production. Various germplasm from CIMMYT and other programs had been used in OPV Program, such as Pool 17, Pool 18, Pop.26, Pop.28, Pop.31, Pop.36, Pop.49, Pop.63, Tuxpeno, Suwan-l and Suwan-2, for the release of 5 OPVs, namely, MSB-2649 (Viamit), VN-l, CV-l, TSB-3, (sweet corn), VN-2 (waxy corn). Those varieties had yield ranging from 3-6 T/ha.|In parallel, hybrid maize program has carried out a hybrid development program since 1973. It has been given top priority in maize breeding program since 1985. The objective of this program is to develop hybrids with high yield, good quality, tolerant to adverse conditions such as drought, saline acid soil, low investment, and resistance to the main diseases in the country .Early hybrids with short plant height have been emphasized.|There are two orientations in our Maize Breeding Program; one is to develop non-conventional hybrids, and the other to develop conventional hybrids. Six non-conventional hybrids with yield potential of 4- 7 T/ha had been released for production. In recent years, conventional hybrids have been emphasized and 12 conventional hybrids have been widely tested and produced with yield potentials of 5-12 T/ha, they are: LVN-l, LVN-4, LVN-5, LVN-10, LVN-ll, LVN-12, LVN-16, LVN-17, LVN-18, LVN-19, LVN-20, LVN26, and LVN-32. In addition, agronomc research has been conducted in order to take full advantage of new OPVs and hybrids.|In 1997 the area planted with hybrids was 43%. By the 2000, the maize area will reach to 0.8-1 million ha, accounting for 60- 70% of the maize area, with average yield of 3 T/ha.|The success can be attributed to the kind assistance of CIMMYT and FAO in staff training and providing initial germplasm, as well as for the effectiveness of the projects.
