摘要:

【Objective】This research screened out sugarcane ratoon stunting disease (RSD) germplasm resources in order to breed better sugarcane varieties with excellent RSD resistance trait. 【Method】By infusing 100 sugarcane varieties from 6 series using the sugarcane seedling-soaking method, the varieties were tested with the established PSD-PCR detection method, the RSD incidence rate in the sugarcane varieties were calculated, and the sugarcane germplasm resources underwent resistance evaluation. 【Result】Within the 100 tested sugarcane varieties, the RSD incidence rates of GT02/351, CP89/2134, ROC26, Yue 94/28, Funong 89/209, and Ya 96/45 were 0% and were rated with grade A resistance; the RSD incidence rates of GT99/181, GT97/228, and GT90/95 were less than 10% and were rated with grade B resistance. GT02/208, GT96/156, and ROC22 were all rated with grade C resistance, while GT21, GT02/237, and CP88/1762 were all rated with grade D resistance. Within the 6 different series, the RSD incidence rate of CP series averaged the lowest at 12%, therefore exhibiting the strongest resistance; the RSD incidence rate of Yuetang series averaged the highest at 28.57%, therefore exhibiting the weakest resistance. 【Conclusion】The sugarcane varieties GT02/351, CP89/2134, ROC26, Yue 94/28, Funong 89/209, and Ya 96/45 displayed excellent resistance quality, thereby demonstrated widespread application values. Within all the sugarcane series, the CP series showed the strongest resistance and could be used as anti-RSD breeding material.
