摘　　要：为了解甘蔗亲本组合的遗传特性和育种潜力,准确地评价筛选甘蔗杂交亲本组合,采用甘蔗家系评价试验方法,利用R软件计算亲本和组合的主要性状的配合力,对126个亲本、146个组合的蔗产量、锤度、锤重配合力进行聚类分析。结果筛选出适合作母本的高糖高产类的甘蔗亲本15个,适合作父本的高糖高产类的甘蔗亲本13个;筛选出高糖高产类甘蔗杂交组合13个。结果表明,利用甘蔗配合力+聚类分析方法可有效地对甘蔗杂交亲本组合进行综合分析。YT00-236×GT96-211、GT02-761×NJ03-218和CP92-1167×CP07-2547这3个组合配合力高,综合性状较好,可作为甘蔗杂交育种的生产性组合加以利用。The objective of the present study was to understand the genetic characteristics and breeding potential of sugarcane crosses and parents,and to evaluate and screen sugarcane crosses and parents accurately.Family test of 146 crosses,including 126 parents,was carried on.Combining ability of the main traits of parents and crosses was calculated by R software,and cluster analysis was calculated by combining abilities of cane yield,brix,and sugar yield.15 female parents,13 male parents,and 13 crosses were selected with high combining ability of yield and sugar,respectively.Combining ability+cluster analysis method could be used to make a comprehensive analysis of the sugarcane parents and crosses.Crosses YT00-236×GT96-211,GT02-761×NJ03-218,and CP92-1167×CP07-2547 with better combining ability and comprehensive characters could be used as the productive crosses in sugarcane breeding.
