甘蔗花叶病是中国蔗区危害最严重的病毒病,利用抗病品种是控制该病害最经济有效的方法。本研究以中国蔗区甘蔗花叶病的2种主要病原甘蔗线条花叶病毒分离物(SCSMV-JP1,GenBank登录号JF488064)和高粱花叶病毒分离物(SrMV-HH,GenBank登录号DQ530434)为接种毒源,采用人工切茎接种和RT-PCR检测相结合方法,于2015年、2016年2次对中国近年选育的71个优良甘蔗新品种(系)进行了双抗SCSMV和SrMV鉴定与评价。结果表明:71个优良甘蔗新品种(系)中,对SCSMV表现高抗到中抗的有24个,占33.8%,感病到高感的有47个,占66.2%;对SrMV表现高抗到中抗的有27个,占38.03%,感病到高感的有44个,占61.97%。综合分析结果显示,福农30号、福农36号、闽糖01-77、桂糖02-467、柳城05-129、粤甘34号、粤甘40号、粤糖55号、粤糖96-86、粤糖00-318、赣蔗02-70、云蔗03-258、云蔗04-241、云蔗05-51、云蔗06-80等15个优良新品种(系)双抗SCSMV和SrMV 2种病毒,占21.13%,其中粤甘34号、粤糖55号、云蔗03-258、云蔗05-51、云蔗06-80等5个优良新品种(系)对2种病毒均表现为高抗,占7.04%,。研究结果明确了71个甘蔗优良新品种(系)对甘蔗花叶病2种主要致病病原的抗性,筛选出双抗SCSMV和SrMV的甘蔗优良新品种(系) 15个,为生产用种选择和有效防控甘蔗花叶病提供了科学依据。 |

Sugarcane mosaic disease is the most serious viral disease in sugarcane growing area of China.The use of resistant varieties is the most economic and effective method to control this disease.Sugarcane streak mosaic virus (SCSMV) and Sorghum mosaic virus (SrMV) are the two predominant pathogens of mosaic disease in the cane-growing regions of China.In 2015 and 2016,double resistance to SCSMV and SrMV was identified and evaluated in 71 new elite sugarcane varieties/clones bred from China Sugarcane system by stem inoculation followed by RT-PCR detection.The results showed that out of 71 new elite sugarcane varieties/clones,24 (33.8%) were highly to moderately resistant,and 47 (66.2%) were susceptible to highly susceptible to SCSMV;Wherease,27 (38.03%) were highly to moderately resistant,and 44 (61.97%) were susceptible to highly susceptible to SrMV.Fifteen new elite sugarcane varieties/clones (21.13%) were highly resistant to resistant to SCSMV and SrMV.The resistant ones/varieties were Funong 30,Funong 36,Minting 01-77,Guitang 02-467,Liucheng 05-129,Yuegan 34,Yuegan 40,Yuetang 55,Yuetang 96-86,Yuetang 00-318,Ganzhe 02-70,Yunzhe 03-258,Yunzhe 04-241,Yunzhe 05-51 and Yunzhe 06-80.Of these,five new elite sugarcane varieties/clones (Yuegan 34,Yuetang 55,Yunzhe 03-258,Yunzhe 05-51,Yunzhe 06-80) were the highly resistant to SCSMV and SrMV,accounting for 7.04% of the total varieties/clones.The results in the present study have determined the resistance of 71 new elite sugarcane varieties/clones to the two main pathogens of mosaic disease,screened out 15 new elite sugarcane varieties/clones resistant to SCSMV and SrMV.These results will provide a basis for the source of resistance in production and effective control of sugarcane mosaic disease. |
