-----------------------------------------------------
Eight red grain sorghum (pure lines) were compared to Suphanburi 1 (SP 1) and Suphanburi 60 (SP 60), two released cultivars from Department of Agriculture (DOA). The test sites were Nakhon Sawan Field Crops Research Centre (NSFCRC), Suphanburi Field Crops Research Centre (SPFCRC), and Pha-phutthabat Field Crops Experiment Station (PBFCES) in 1998, late rainy season to studied response to environments of these varieties. The result revealed that at NSFCRC all varieties are not statistically different in yield potential, but UT 1067 B gave the highest yield compared to others. At SPFCRC only 4 varieties yield higher than SP 1 and SP 60. While at PBFCES, most varieties yield higher than SP 1 but no any varieties yield statistically different from SP 60
