ZHANG Gui-lian 1,TU Nai-mei 1,ZHANG Shun-tang 2 (1.College of Agronomy,HNAU,Changsha 410128, PRC;2.Commission for Inspecting Discipline of Linwu County,Linwu 424300,PRC)  
The comparison of ratooning characteristics of 6 different hybrid rice combinations were studied under the condition of the same culture.The result shows that the combinations with longer growth stage and higher dry matter production at late stage of main crop and higher soluable carbohydrate in stem were of better ratooning ability. The differences of average yield of main crop between varieties did not reach significant level. There was significant difference of the axillary bud sprouting in ratooning rice because of the difference of ratooning ability between different combinations. So there were significant differences of grain yield in ratooning rice, the yields of Peiai64S/E32 and Peiliangyou500 were 26.19% and 23.81% higher than that of Shanyou63 respectively, reaching an extreme significant level.Therefore Peiai64S/E32,Peiliangyou500 can be used as ratooning varieties in Hunan.
