Abstract
The purpose of this study was to detect the status of Fiji disease virus (FDV) and leaf scald (Xanthomonas albilineans) in the newly introduced sugarcane germplasms from USA and Vietnam, and observe their agronomic performances in Guangxi sugarcane growing area, thus to provide references for screening healthy sugarcane germplasm. Following the quarantine procedure, 41 newly introduced sugarcane germplasm accessions were planted in isolated quarantine area for FDV and leaf scald detection. The PCR (RT-PCR) results showed the reaction to FDV and leaf scald were both negative and no quarantine disease occurred. Further, field experiments were conducted to observe their agronomic performance and resistance to commom diseases, like red rot, yellow spot, ring spot, pokkah boeng, mosaic, smut, rust and brown stripe diseases, and the results showed that 18 germplasm accessions were resistant to these diseases. Based on the experimental results, 8 accessions from USA and 4 accessions from Vietnam were selected for the next variety test. This study would provide excellent resistant germplasm materials and scientific references for further sugarcane disease resistance breeding.
