摘要： Sugarcane mosaic disease is one of the most serious and prevalent viral diseases of sugarcane in China. Resistant varieties are the most economical and effective measures for controlling this disease. Resistance against Sugarcane streak mosaic virus (SCSMV) and Sorghum mosaic virus (SrMV) in 41 excellent sugarcane innovation germplasms and their parents (Saccharum officinarum L. LudashixErianthus rockii Keng Yundian 95-19) was checked by using a stalk inoculation and RT-PCR detection during 2015 and 2016. Results indicated that among the 41 excellent sugarcane innovation germplasms and parents, 23 were highly (Grade 1) to moderately resistant (Grade 3) to SCSMV, meanwhile, 31 were highly (Grade 1) to moderately resistant (Grade 3) to SrMV. Ten germplasms were highly resistant (Grade 1) to resistant (Grade 2) to both SCSMV and SrMV. Among these, six germplasms (Yun 09-604, Yun 09-607, Yun 09-619, Yun 09-633, Yun 09-656, Yundian 95-19) were highly resistant (Grade 1) to both SCSMV and SrMV, accounting for 13.95% of the total germplasmmaterials. These results may provide resistance resource available for the breeding program of sugarcane cultivars against the major vrius associated withmosaic diseasein China.
