摘　　要：采取田间自然诱发的方式,对桂林34个水稻主栽品种进行南方水稻黑条矮缩病抗性评价,结果表明:表现为抗病的有淦鑫203、顺优109、株两优4024、T78优2155、岳优9113、中浙优8号、中浙优1号、Y两优302、桂两优2号等14个品种;表现为感病的有陆两优28、EK优18、淦鑫206、五优308、淦鑫699、丰源优299、Q优6号、丰两优4号等20个品种;未发现免疫品种。建议农户选用上述抗性较好的品种,慎用高感品种。同时,在现阶段,"治虱防矮"仍然是防治水稻南方黑条矮缩病的最主要措施。Taking the way of induced in field,the resistance of 34 main rice cultivars were evaluated to southern rice black-streaked dwarf disease（SRBSDD）in Guilin.The results indicated that 14 cultivars were resistant,including Ganxin 203,Shunyou 109,Zhuliangyou 4024,T78you 2155,Yueyou 9113,Zhongzheyou 8,Zhongzheyou 1,Y Liangyhou 302,Guiliangyou 2,etc..20 cultivars were susceptible,including Luliangyou 28,EKyou 18,Ganxin 206,Wuyou 308,Ganxin 699,Fengyuanyou 299,Q you 6,Fengliangyou 4,etc..No immune cultivars were found in this trial.These resistant cultivars were recommended farmer to choose,highly susceptible varieties would be caution.At the same time,“control rice planthoppers for prevent SRBSDD”was still the main measure in the present stage.
