Summary:Corn Breeding Project has put a lot of efforts in research and development for a long period of time and finally got a new variety named "Suwan 3". It was officially released by Kasetsart University and the Department of Agriculture in 1987. Suwan 3 gave yield higher than Suwan 1 approximately 8 percent for the past four years testing in corn belt areas both in experiment stations and farmer fields. This variety also contained other desirable characters such as resistance to corn downy mildew and Southern rust, resistance to lodging due to better root and stalk quality, and the accepable grain type. Another success in this year, the project released eight new inbreds, Ki 23 to Ki 30. They have general combining ability better than the previous lines. They are also highly resistant to corn downy mildew. The promising hybrids (KSX 2903 and KTX 2903), tested at different corn belt areas during 1985-1987, gave yield higher than KTX 2602 approximately 7 and 13 percent and yielded higher than Suwan 1 18 and 18 %, respectively.
