摘　　要：经预试品比试验获得了川糖12-1159、川糖12-1144、川糖09-1116、川糖10-2099和川糖10-2183这5个果蔗新品系,为更好地掌握各新品系的特性及宿根性,我们进行了1年新植1年宿根的品比试验。试验以川蔗13号(CK1)、粤糖58-489(CK2)和华南54-11(CK3)为对照,并运用DTOPSIS法对8个品种(系)进行综合评价。试验结果表明:川糖10-2183宿根虽有轻微的倒伏发生,但其口感好、外形美观、产量高、抗逆性和宿根性强,综合性表现较优秀,排名第2,其Ci值为0.68073,仅次于CK2;川糖12-1159虽宿根性略差,但其口感好、外形美观、抗逆性强、产量较高,综合表现较优秀,排名第4,其Ci值为0.54343,高于CK3;其余品系的Ci值不及3个对照,综合性状较差。川糖10-2183和川糖12-1159这2个品系可考虑进入区域和示范试验,以培育新的高产优质的果蔗新品种。5 new chewing cane strains were obtained through the pre-comparison test,including Chuantang12-1159,Chuantang12-1144,Chuantang09-1116,Chuantang10-2099 and Chuantang10-2183.In order to better master the planting and rooting characters of each new strain,the comparative tests of one year planting and one year rooting were conducted out on 5 chewing cane strains.Chuanzhe13(CK1),Yuetang58-489(CK2)and Huanan54-11(CK3)were used as the control in the experiment,and 8 varieties(strains)were comprehensively evaluated by DTOPSIS method.The results showed that although the rooting of Chuantang10-2183 was slight lodging,but its comprehensive traits was excellent due to its good taste,beautiful appearance,highest yield,strong resistance and strong rooting.The Ci value of Chuantang10-2183 was 0.68073 and was second only to that of CK2.Although the rooting of Chuantang12-1159 was not better than CK3,but its comprehensive traits was excellent too due to its good taste,beautiful appearance,strong resistance and higher yield.The Ci value of Chuantang12-1159 was 0.54343,only higher than that of CK3.The Ci values of other strains were not as good as those of all the control,and the comprehensive characters were poor.The two strains of Chuantang10-2183 and Chuantang12-1159 can be considered to enter into regional trials and demonstration trials to cultivate new varieties of chewing cane with high yield and high quality.
