Occurrence of Fusarium oxysporum f.sp.cubense tropical race 4 and resistance identification of banana varieties in Guangxi
摘要
Abstract
[Objective]Occurrence status of Fusarum oxysporum f.sp.cubense tropical race 4 in Guangxi was surveyed and the resistance of banana varieties cultivated in Guangxi against Fusarium oxysporum f.sp.cubense tropical race 4 was also studied to provide references for formulating the corresponding prevention and control measures.[Method]The condition of Fusarium oxysporum f.sp.cubense tropical race 4 infecting the banana was investigated in 2-3 spots of 23 villages randomly chosen from Guangxi was.Furthermore,the resistance of eleven banana varieties cultivated against Fusarium oxysporum f.sp.cubense tropical race 4 was determined using injury root inoculation method.[Result]Fusarium oxysporum f.sp.cubense tropical race 4 was found in Qinzhou City,Wuming County,Longan County,Longzhou County,and Xixiangtang District,in which the diseased plant rates were 1.00％-14.00％.All of the eleven banana varieties were highly sensitive (disease index:70.00-100.00) to Fusarium oxysporum f.sp.cubense tropical race 4 except Jinfen 1 which was sensitive (disease index:50.00).Fusarium oxysporum f.sp.cubense tropical race 4 was not present in the investigation spots of Tiandong County.[Conclusion]Fusarium oxysporum f.sp.cubense tropical race 4 was found sporadical in a part banana production area of Guangxi and propagated rapidly.Since banana varieties cultivated in Guangxi were highly sensitive or sensitive to Fusarium oxysporum f.sp.cubense tropical race 4,their disease-resistant ability was poor.More efforts should be made to prevent and control Fusarium oxysporum f.sp.cubense tropical race 4.关键词
