摘　　要：分析台糖系列甘蔗亲本组合杂交后代群体的农艺性状,筛选出优良亲本组合,为甘蔗杂交育种提供参考依据。以11个台糖系列亲本及其与国内外品种选配的11个组合为材料,应用DTOPSIS法对其杂交后代群体的株高、茎径、锤度、丛重、锤重、空蒲心率进行综合评价。结果表明,杂交组合ROC 25×桂糖92-66的综合表现优于ROC 22(ck),可重点观察后代群体,亦可列为生产性杂交组合计划,适当加大杂交力度。In this study,the agronomic traits of the progeny population crossed by sugarcane parents of Taitang series were analyzed,which could screen out the good parent combination,and provide reference for sugarcane cross breeding.The plant height,stem diameter,brix,clump weight,brix weight and hole rate of the hybrid progeny population were evaluated by DTOPSIS method with 11 parents of Taisang series and their 11 combinations selected with domestic and foreign varieties.The results showed that the comprehensive performance of hybrid from ROC 25 corssed by Guitang 92-66 was better than ROC 22(ck),which could be used to focus on the progeny population,and could also be listed as a productive hybrid program,and the hybridization intensity should be increased appropriately.
