| 摘 要： | 以新台糖22号（ROC22）为对照,对9个甘蔗新品系进行1年新植和2年宿根比较试验,利用方差分析和DTOPSIS法进行评价。结果表明,9个参试品系中桂糖11-80、桂糖11-2142和柳糖10-21的2年宿根黑穗病发病率高于ROC22,其他品系则低于ROC22,其中桂糖10-517第1年宿根发病率为0,桂糖10-434 2年宿根发病率均为0。通过DTOPSIS法综合评价,理想解相对接近度（Ci）低于ROC22的品系有桂糖10-3006和桂糖10-517,表现出低产和低糖等特点;Ci高于ROC22的品系有桂糖10-2018、桂糖10-434、河糖11-145和桂糖10-2003,表现出高产高糖且抗逆性强等优良特性,适合在广西崇左蔗区及气候条件相似的蔗区推广种植。

| Abstract: | The nine new sugarcane clones were evaluated comprehensively by variance analysis and the DTOPSIS method taking ROC22 as a control in new-planted cane and two years ratoon crops. The results showed that the smut rates of Guitang 11-80, Guitang 11-2142, and Liutang 10-21 were higher than ROC22 in two years ratoon crops, while the smut rates of other clones were lower than ROC22. Among them, the smut rate of Guitang 10-517 was 0 in the first year ratoon, and the smut rate of Guitang 10-434 was 0 in two years ratoon crops. The DTOPSIS analysis results showed that the Ci of Guitang 10-3006 and Guitang 10-517 were lower than that of ROC22, the two clones were characterized by lower cane yield and lower sucrose content. The Ci of Guitang 10-2018, Guitang 10-434, Hetang 11-145, and Guitang 10-2003 were higher than that of ROC22, the four clones were characterized by higher cane yield, higher sucrose content, and strong resistance, they are suitable for planting in Chongzuo and other sugarcane planting areas with the similar environmental conditions. |
