为了筛选适合我国主产蔗区的优良品种,为推广提供依据,特对全国9个甘蔗新品种进行研究,以Roc22号作对照。研究结果表明:萌芽率较高的品种是粤糖55、福农15、桂糖02-901、粤糖00-236,分蘖率高的有粤糖55、粤糖00-236,蔗茎产量高于对照的有粤糖55、桂糖97-69、粤糖00-236和福农15等4个品种,蔗糖分较高的是桂糖02-901和云蔗99-91,耐寒性较强的是云蔗99-91、云蔗03-422、粤糖55、粤糖00-236等4个品种,公顷含糖量较高的是粤糖55、福农15、粤糖00-236、桂糖97-69。综合性状表现较好的是粤糖00-236和福农15号,可作为优良品种在主产蔗区推广。
In order to screen the best varieties of sugarcane for our country to provide the basis for the promotion, especially for 9 new sugarcane varieties in the country, with Roc22 as a control. The results showed that the varieties with higher germination rate were Yuetang 55, Funong 15, Guitang 02-901, and Yueshun 00-236. The varieties with high tillering rate were Yue Tang 55, Yue Tang 00-236, and the high cane yield In contrast, there are four varieties of Yue sugar 55, Gui sugar 97-69, Yue sugar 00-236 and Funong 15, the higher sugar content is Gui sugar 02-901 and cloud sugarcane 99-91, strong cold tolerance Of which are Yunxian 99-91, Yunxian 03-422, Yantang 55 and Yueshun 00-236, etc. The higher sugar content of the hectare is Yuesang 55, 福农 15, Yueshang 00-236, Gui sugar 97-69. Good performance of the integrated traits of Guangdong sugar 00-236 and Funong 15, can be used as good varieties in the main sugarcane area to promote.
