水稻品种对病毒病的抗性研究

本文报道水稻品种对黄叶病(RTYV)、矮缩病(RDV)、簇矮病(RBSV)和锯齿叶矮缩病(RRSV)的抗性鉴定研究结果。研究指出,水稻对各种病毒病的抗性依品种不同而有显著差异。从中发现赤块矮3号这一典型晚籼品种表现最好,能兼抗本文提到的四种病毒病。并且认为抗性表现较好的尚有抗黄叶病的691、广二矮5号,抗矮缩病的Tetep、古巴154,抗簇矮病的包胎矮、珍龙13号,抗锯齿叶矮缩病的赤块矮选和三农3号等,可供病区推广使用或作为抗病育种的抗源材料。

STUDIES ON THE RESISTANCE OF RICE VARIETIES TO VIRUSES

The present report deals with the determination of the resisiatance of rice varieties to RTYV(RYSV).RDV.RBSV and RRSV. 1.Among the 219 varieties tested during 1973-1975,none of the tested varieties were immune to RTYV and RDV. More than 15 varieties were considered to be highly resistant to RTYV such as Chikuaiai 3,691,Tadukan.Longge 1 and Longge 113 etc.37 varieties were moderately resistant,such as Zhenlong 13 and Wanxian 1 etc.79 varieties were moderately susceptible,such as Shaaida and Lucai etc.88 varieties were highly susceptible,such as Zhenzuai 11 and Short white seeder etc. 34 varieties were highly resistant to RDV.such as Tetep.Chikuaiai 3. Guba 154 and Mudgo etc;and 39 varieties were moderately resistant,such as Malaihong,Nongshi 4 and Zhenlong 13 etc.51 varieties were moderately susceptible,such as Zhenshan 97 and Chaiyeching 8 etc;and 95 varieties were highly susceptible,such as IR 24 and IR 24x TN-1 etc.. 2.Among the 16 varieties tested during 1978,1981,none of them were immune to RBSV.The highly resistant varieties were Chikuaiai 3.and Baotaiai; moderately resistant varieties were Cuba 154,Zhenlong 13,Zhenlong 410 and Nongshi 4;and moderately susceptible varieties were Longge 16.IR 24.V 41 and V 20;while the others were all highly susceptible. 3.Among the 32 varieties tested during 1980-1981.none of them were immune to RRSV.The highly resistant varieties were Chikuaiai 3,Shannung 3,Shannung 8 and Chikuaiai-Xiuan;the moderately resistant varieties were IR 30-Xiuan,Baotaiai,Fengaizao AxDT Ai;while moderately susceptible varieties were IR 2061-427-1-17-7-5,IR 29,IR 30 and IR 36 etc.The highly susceptible varieties were puichao 2,IR 24,Siyou 4 and Shanyou 6.
