摘　　要：以45个家系甘蔗实生苗为供试材料,对蔗茎产量、甘蔗蔗糖分、有效茎、茎径、株高、甘蔗纤维分6个影响甘蔗产业经济效益最大的主要数量性状进行了经济遗传值(经济育种值)分析,结果表明:29个母本中,粤农73-204、德蔗93-88、CP84-1198、粤糖85-177、HoCP93-746、桂糖96-44、云蔗89-351、CP88-2143和湛蔗74-141等经济育种值高;26个父本中,CP84-1198、福农91-4621、粤糖89-240、CP81-1254、桂糖00-122、云瑞99-601、云瑞05-808、云瑞03-806、ROC22和福农95-1702等经济育种值高;45个家系中粤农73-204×CP84-1198、福农91-4710×粤糖89-240、HoCP93-746×福农91-4621、CP84-1198×ROC22、粤糖91-976×CP84-1198、HoCP93-746×ROC22、CP88-2143×粤糖97-76、桂糖96-44×ROC10、云蔗89-351×CP84-1198、湛蔗74-141×CP81-1254、HoCP93-746×湛蔗74-141、德蔗93-88×云瑞99-601、ROC11×桂糖91-116等经济遗传值高,可作为选育甘蔗新品种的重点家系。Sugarcane seedlings from 45 families were used as testing materials in this study,and economic genetic values （or economic breeding values） were analyzed for 6 important quantitative characters which mostly influenced the commercial benefit,i.e., the cane yield,stalk number,diameter,plant height,sugar and fiber contents in cane. The results showed that economic breeding values were high for Yuenong73-204,Dezhe93-88, CP84-1198, Yuetang85 - 177, HoCP93 -746, Guitang96-44, Yunzhe89-351, CP88-2143 and Zhanzhe74-141 in the 29 female parents ;and CP84 -1198, Funong91 -4621,Yuetang89 -240,CP81 -1254, GuitangO0 -122, Yunrui99-601,Yunrui05-808,Yunrui03-806,ROC22 and Funong95-1702 in the 26 male parents. The family economic genetic values were high for Yuenong73-204 × CP84-1198,Funong91-4710 ×Yuetang89-240, HoCP93 -746 ×-4621, CP84 - 1198 ×ROC22, Yuetang91 -976 × CP84 - 1198, HoCP93 -746 ×ROC22, CP88 -2143 ×Yuetang97 -76, Guitang96 -44 ×ROC 10, Yunzhe89 -351 × CP84 - 1198, Zhanzhe 74 - 141 ×CP81 - 1254, HoCP93 -746 xZhanzhe74-141, Dezhe93-88 ×Yunrui99-601 and ROC 11 ×Guitang91 - 116 in 45 families. They could be considered as the most important families for variety breeding.
