摘　　要：为评价崖城系列甘蔗亲本的遗传特点和组合的选配效果,采用澳大利亚家系试验法,借助R软件对41家系F1群体的株高、茎径、有效茎、蔗茎产量、锤度等5个主要数量性状进行遗传变异、遗传方差及经济育种值（EBV）分析.结果表明：株高和蔗茎产量受父母本加性基因效应和非加性基因效应所制约,茎径受母本加性基因效应和非加性基因效应所制约,锤度受母本加性基因效应所制约,有效茎受非加性基因效应所制约.17个母本经济育种值变幅为-2757.12 ～ 3068.17元,有8个母本经济育种值为正值;20个父本经济育种值变幅为-2334.20 ～2337.79元,有12个父本经济育种值为正值;41个家系经济育种值变幅为-7276.52～6173.43元,有20个家系经济育种值为正值.17个母本中,崖城71-374、崖城08-01-10、崖城82-96、崖城97-46及崖城73-226等5个亲本可作为生产性母本,建议加大力度使用.20个父本中,崖城84-153、崖城84-125、崖城09-84、崖城07-71、崖城98-2及崖城93-26等6个亲本可作为生产性父本,建议加大力度使用.41个家系中,ROC22×崖城84-153、福农02-6427×崖城06-140、崖城91-58×粤糖93-159、崖城82-96×ROC22、崖城93-26×云蔗02-2540、崖城71-374× ROC22等6个家系可作为生产性家系该批组合易选育出高经济效益的新品种,建议加大力度使用.In this paper,Australian family test was conducted to evaluate genetic characteristics of yacheng series sugarcane parents and the effect of matching of cross.The plant height,stalk diameter,millable stalks,cane yield and brix of 41 F1 groups were studied by R sofeware,and their genetic variation,genetic variance and economic breeding value（EBV） wee analyzed.The result showed that the plant height and cane yield were restricted by additive gene and non-additive gene of parents,stalk diameter by additive gene and non-additive gene offemale parent,brix by additive gene effect of female parent,and millable stalk by non-additive gene effect of female parent.The EBV of 17 mothers were from-2757.12 to 3068.17 yuan,of which EBV of 8 mothers were above zero; The EBV of 20 fathee were from-2334.20 to 2337.79 yuan,of which EBV of 12 fathers wee above zero; The EBV of 41 families wee from-7276.52 to 6173.43 yuan,of which EBV of 20 families were above zero.Among the 17 mothers,Ya cheng71-374,yc08-01-10,yacheng82-96,yacheng97-46,yacheng73-226 wee suggested to use in cross breeding.Among the 20 fathers,yacheng84-153,yacheng84-125,yacheng09-84,yacheng07-71,yacheng98-2 and yacheng93-26 were suggested to use in cross breeding.Among the 41 families new valiaty which has more economic benefit could be selected more easily from these cross：ROC22 × yacheng 84-153,funong02-6427 × yacheng06-140,yacheng91-58 × yuetang93-159,yacheng82-96 × ROC22,yacheng93-26 × yunzhe02-2540,yacheng71-374 × ROC22,these cross combinations would be used widely in sugarcane breeding.
