| 摘 要： | 在田间自然条件下．在分蘖期、拔节期和成熟期分别对热引1号、热引2号和ROC22号进行虫害调查。对分蘖期枯心率、拔节期和成熟期虫蛀孔数的结果分析表明，在3个不同生长时期，这3个甘蔗材料间对螟虫的抗性均差异显著，抗性依次为热引1号、ROC22、热引2号。因此，与当前主栽品种ROC22相比，热引1号可作为选育抗螟虫甘蔗品种的优良亲本，为抗螟虫甘蔗品种的选育提供良好基础材料。

| Abstract: | The resistance of RY1, RY2 and ROC22 to borers was measured at tillering stage, at elongation stage and at maturing stage under the field condition. The analyzed results of the dead heart rate at tillering stage, the number of bored holes at elongation and maturing stage indicated that the difference of the resistance of three sugarcane materials was all significant at three stages. Among three sugarcane materials, the resistance of RY1 is the highest, and then ROC22 and RY2. Therefore, compared to ROC22 which is the major cultivar in our country, RY1 would be the excellent parents for the selection and breeding of cultivar resistant to borers. |
