Abstract

Mosaic disease is a systemic, seed-cane transmitted disease in sugarcane. Selective breeding and planting of resistant varieties is the most economical and effective measure for controlling this disease. In this study, resistance to Sorghum mosaic virus (SrMV-HH, GenBank accession number DQ530434), the predominant pathogen of mosaic disease in the Chinese cane-growing regions, was evaluated in 49 new elite sugarcane varieties/clones. Resistance ratings were determined as disease incidence after a stalk-cutting inoculation and RT-PCR detection in 2011 and 2012. Disease incidence under natural conditions was also used as a reference for resistance rating. The results demonstrated that of the 49 varieties/clones tested, 31 (63%) were scored between highly resistant (Grade 1) to moderately resistant (Grade 3). Of these, nine (18%; Yuegan 40, Yuegan 42, Yuetang 55, Yunzhe 03-194, Yunzhe 99-596, Yunrui 06-189, Guitang 30, Dezhe 03-83, and Mintang 01-77) were highly resistant (Grade 1), and seven (14%; Funong 0335, Liucheng 05-129, Yuetang 96-86, Yunzhe 01-1413, Yunzhe 03-258, Yunzhe 06-80, and Guitang 02-351) were resistant (Grade 2). These results may facilitate future efforts to breed varieties with further improved resistance to SrMV and may provide elite resistance resources and a reference for selecting and planting elite resistant varieties to control sugarcane mosaic disease effectively.
