摘　　要：为了解美国引进的HoCP系列甘蔗种质资源的育种价值,本研究以HoCP00-1142、HoCP01-517、HoCP01-564、HoCP02-610、HoCP02-623、HoCP03-704、HoCP03-708、HoCP03-716、HoCP05-902、HoCP07-613、HoCP07-617和HoCP92-648等12个HoCP品系为核心亲本配置了73个杂交组合,采用家系评价方法,对12个HoCP系列亲本及其73个组合F1群体的株高、茎径、有效茎数、蔗糖分和蔗茎产量等5个主要性状的配合力效应值、经济育种值等参数进行估算。结果表明,5个性状中除了株高在母本间无差异,其他性状在母本、父本及组合间均存在显著差异。作为母本,11个亲本当中HoCP03-704的株高,HoCP02-623的茎径,HoCP02-610的有效茎数,HoCP07-617的蔗糖分及HoCP92-648的蔗茎产量一般配合力最高;而作为父本HoCP03-704的株高,HoCP02-623的茎径,HoCP07-617的有效茎数,HoCP03-708的蔗糖分及HoCP02-623的蔗茎产量的一般配合力最高。从经济育种值来看,HoCP02-623、HoCP03-708和HoCP92-648作为母本经济育种值较高,同时蔗糖分和蔗茎产量的一般配合力效应值也较高,适宜作高产高糖的母本。HoCP01-517和HoCP07-617作为父本的经济育种值较高,同时在蔗糖分和蔗茎产量的一般配合力效应值较高,适宜作高产高糖的父本。73个组合中,以HoCP03-704ב内江03-218’的株高,‘粤糖00-236’×HoCP00-1142的茎径,‘崖城07-71’×HoCP05-902的有效茎数,‘粤糖00-236’×HoCP03-708的蔗糖分,HoCP01-564ב桂糖92-66’的蔗茎产量的特殊配合力最高。38个组合的经济育种值为正值,其中‘粤糖94-128’×HoCP01-517,HoCP01-564ב桂糖92-66’、‘桂糖02-467’×HoCP01-564等组合蔗茎产量和蔗糖分特殊配合力和组合经济育种值均较优,可作为今后重点的生产性家系,而HoCP03-716ב福农02-6404’,‘粤糖99-66’×HoCP01-564和‘粤农73-204’×HoCP01-564等组合的各性状的特殊配合力较低,同时经济育种值也低,不适宜作为生产性家系应用。以In order to assess the breeding value of HoCP series sugarcane germplasms introduced from USA,12 HoCP sugarcane clones(HoCP00-1142,HoCP01-517,HoCP01-564,HoCP02-610,HoCP02-623,HoCP03-704,HoCP03-708,HoCP03-716,HoCP05-902,HoCP07-613,HoCP07-617 and HoCP92-648)were used as core parents in 73 sugarcane cross combinations.The effect on combining ability,economic breeding values of height,diameter,effective stem number,sugar content and cane yield for the 11 HoCP sugarcane parents and 73 F1 population were estimated using the family test method.Significant differences were found for height among HoCP males and cross combinations,whereas no significant differences were detected for height among HoCP females,suggesting that the plant height was affected by only male and cross combination.For the stem diameter,effective stem number,sugar content and cane yield,there were significant differences existed among different HoCP female,male and cross combination,indicating that the four characters were affected by female,male and cross combination.Among the 12 clones,the highest general combining ability for height,diameter,effective stem number,sugar content and cane yield appeared in HoCP03-704,HoCP02-623,HoCP02-610,HoCP07-617,and HoCP92-648 as female,respectively,while HoCP03-704,HoCP02-623,HoCP07-617,HoCP03-708 and HoCP02-623 as male possessed the highest general combining ability for height,diameter,effective stem number,sugar content and cane yield,respectively.The better economy breeding value(EBV)and general com-bining ability(GCA)in cane yield and sugar content were detected in HoCP02-623,HoCP03-708 and HoCP92-648 as the female,and HoCP01-517and HoCP07-617 as the male,which indicated that the clones could be used as excellent female and male with high-yield and hight-sugar,respectively.Among the 73 cross combinations,the highest special combining ability for height,diameter,effective stem number,sugar content and cane yield appeared in HoCP03-704בNeijiang 03-218’,‘Yuetang 00-236’×HoCP00-1142,‘Yacheng 07-71�
