the sugarcane production having high quality is favorable.Sugarcane varieties having high quality or CCS are the important factor in farm for increasing sugar yield by having small effect to cost of production. Stability in CCS of Kamphaeng Saen sugarcane varieties series 2007 evaluating by GGE biplot were conducted to find out the high potential varieties in CCS for different environments of sugarcane production. GGE biplot was evaluated by individual trials and by grouping of trials by regions, soil texture and harvesting periods. Varietal trials were conducted in RCBD (Randomized Complete Block Design) with 3 replications having ten Kamphaeng Saen sugarcane varieties and Khon Khen 3 as check variyies. Each plot had 3 rows of 8 meter in length from grouping trials by regions revealed that Khon Khen 3 had the highest GE scores in central and western, while Kamphaeng Saen 07-29-1 had the highest scores in northeastern and northern. In the case of grouping trials by soil texture, Kamphaeng Saen 07-29-1 had the highest EG scores in clay soil, loamy sand soil, sandy clay loam soil and sandy loam soil, while Khon Khen 3 had the highest EG scores in silt loam soil and silt clay loam and Kamphaeng Saen 07-24-2 had the highest score in loam soil. In different harvesting periods, Khon Khen 3 had the highest EG scores in early harvesting of 10 and 11 month, while Kamphaeng Saen 07-29-1 had the highest EG scores in late harvesting of 12, 13 and 14 month. Results of this study could be use for decision of suitable sugarcane varieties for high CCS in different environments of sugarcane production in Thailand.
