【Objective】The aim of this experiment was to assess the yield performance and adaptability of new sugarcane varieties and select appropriate ones for planting in Guangxi. 【Method】Comparative production trials of two planting cane and one-year-old ratoon were conducted using 10 new sugarcane varieties and 2 control varieties（ROC22 and ROC16） during 2008-2009 at 8 locations， viz.， Nanning， Liuzhou， Hechi， Baise， Hezhou， Laibin， Chongzuo and Hepu in Guangxi to evaluate the yield performance and adaptability of 10 new sugarcane varieties. 【Result】Amongst the tested varieties， the variety GT 02/208 showed best comprehensive traits with early maturity， high and stable yield of cane and high sugar yield. The varieties LC 03/182 and GT 02/901 were particularly early maturing with high sugar yield and steady cane yield. The varieties GT 02/770 and GT 02/833 were mid-late maturing with high cane yield and medium sugar yield. The varieties GT 02/1247 and LC 03/1137 were late maturing with high cane yield and medium sugar yield. 【Conclusion】The varieties GT 02/208， LC 03/182， GT 02/901， GT 02/770， GT 02/833， GT 02/1247 and LC 03/1137 were suitable to be extended for planting in Guangxi.
