| 摘 要： | 选用13个新台糖系列甘蔗品种ROC1、ROC6、ROC8、ROC9、ROC10、ROC 11、ROC20、ROC22、ROC23、ROC24、ROC25、ROC26和ROC28作母本与不同类型的父本杂交,选配组合31个,采用家系评价法和宿根力分析对甘蔗有性杂交后代在干旱条件下的宿根性进行研究.结果表明:母本及选配的组合对后代宿根蔗的影响较新植蔗更为显著,且蔗茎产量、糖产量和有效茎在宿根蔗的遗传力表现均高于新植蔗,有利于强宿根后代的选育；13个新台糖系列母本中,ROC25、ROC 11和ROC24在新植、宿根两个植期的重要性状一般配合力(GCA)均较高,糖产量、蔗茎产量和锤度在宿根蔗的配合力大于新植蔗,可作为优良抗旱、强宿根母本加以利用；31个组合中,自然干旱条件下组合ROC25×德蔗93-88在2个植期的重要性状特殊配合力(SCA)高于其他组合,糖产量和蔗茎产量宿根力分别比对照种ROC22高13.7％和20.4％,是选育抗旱、强宿根甘蔗新品种的优良组合. |

| Abstract: | Thirty-one cross combinations consisted of thirteen ROC varieties including ROC1,ROC6,ROC8,ROC9,ROC10,ROC11,ROC20,ROC22,ROC23,ROC24,ROC25,ROC26 and ROC28 as female parents were made,and methods of family evaluation and ratooning ability(RA)were combined together for evaluating the ratooning traits of progeny populations under natural drought conditions.The results showed that the progenies were more significantly affected by ratoon crop than plant crop.Moreover,heritability of ratoon crop in cane yield,sugar yield and stalks were higher than that in plant crop,availing to breeding the strong ratoon offspring.Among the thirteen ROC female parents,the general combining ability(GCA)of main traits from ROC25,ROC11 and ROC24 were all higher in plant crop and ratoon crop.Furthermore,values of gca in cane yield,sugar yield and brix of ratoon crop were higher than that of plant crop.Thus these ROC parents could be excellent female parents with drought resistance and strong ratooning traits.The special combining ability(SCA)of main traits in plant crop and ratoon crop of ROC25×Dezhe 93-88 were higher than that of other cross and the ratooning ability of sugar yield and cane yield were 13.7% and 20.4% higher than those in ROC22 respectively.These ROC25×Dezhe 93-88 could be excellent cross for breeding the new varieties which could combat drought and have strong ratoon sugarcane. |
