摘要:

【目的】对国家甘蔗产业技术体系第四轮集成示范桂林点甘蔗新品种的农艺性状进行综合评价,为桂北地区甘蔗新品种的推广提供参考。【方法】以ROC22为对照,利用DTOPSIS法对9个甘蔗新品种的14个农艺性状进行综合评价。【结果】9个集成示范品种中,有7个品种的综合农艺性状表现优于对照ROC22,其中福农1110和柳成03-1137蔗茎、蔗糖产量较高,云蔗05-49、桂糖32和粤甘39有效茎数较多。各品种按照DTOPSIS分析结果Ci排序依次为福农1110>柳城03-1137>粤甘39>桂糖32>云蔗05-49>粤甘42>桂糖31>ROC22(CK)>云蔗99-596>福农0335。【结论】DTOPSIS评价结果与桂北地区田间生产结果一致,福农1110、柳城03-1137、粤甘39、桂糖32、云蔗05-49、粤甘42和桂糖31等品种的综合农艺性状优于对照ROC22,可在桂北地区进一步示范推广。

【Objective】The agronomic traits of sugarcane varieties from the 4th-round national integration and demonstration in Guilin of sugarcane industrial technology system were evaluated, in order to provide reference for extension of these sugarcane varieties in northern Guangxi region. 【Method】Fourteen agronomic traits of nine sugarcane varieties were evaluated comprehensively by DTOPSIS method, with ROC22 as control. 【Result】7 of 9 sugarcane varieties in integration and demonstration had better agronomic traits than ROC22, of which, Funong 1110 and Liucheng 03-1137 had higher cane yield and sucrose yield, and Yunzhe 05-49, Guitang 32 and Yuegan 39 had more effective stalks. And DTOPSIS analysis results showed that, 10 tested sugarcane varieties were ordered based on Ci sequence, as follows: Funong 1110> Liucheng 03-1137>Yuegan 39>Guitang 32>Yunzhe 05-49>Yuegan 42>Guitang 31>ROC22(CK)>Yunzhe 99-596>Funong 0335. 【Conclusion】The DTOPSIS evaluation results were as same as actual production results in field. And the sugarcane varieties such as Funong 1110, Liucheng 03-1137, Yuegan 39, Guitang 32, Yunzhe 05-49, Yuegan 42 and Guitang 31 are superior to ROC22 in aspect of agronomic traits, therefore which should be further extented and demonstrated in northern Guangxi.
