Planting performance of new sugarcane varieties in Liuzhou,Guangxi from 2008 to 2009

The present study has been conducted to screen high yield and quality sugarcane varieties suited for climatic conditions of Liuzhou.A regional trial was conducted using 12 sugarcane varieties which were planted in fields in year 2008 and 2009.After harvesting in 2008,the ratoon was initiated in year 2009 at the farm of Liuzhou Research Institute of Agricultural Sciences.The results revealed that average sucrose yield of variety LC03/182 was the highest and it showed early,high sugar and yield.This variety was suitable for planting in the frost and drought affected fields in the central region of Guagnxi.Average sucrose yield of another variety GT02/833 was slightly less than the previous one and showed late-maturing,high sugar and yield,it could be appropriately extended as middle-late variety.These two varieties were followed by variety LC03/1137 in sucrose yield which showed late-maturing,high yield and good ratoon ability,which may be extended as a middle-late variety.Average sucrose yield of variety GT02/208 ranged fourthly and it showed earlymaturing,high yield and sugar and good ratoon ability,it could be appropriately extended as early variety.Other varieties performed generally in field in Liuzhou City.
