摘要
本试验采用黑龙江省灰斑病菌株30个,分别测定本省70个主要推广品种、品系和资源,直接研究寄主和病原物的相互作用.试验结果认为,在品种、品系和资源中都有感病、抗病和中间类型的材料.在已推广品种和试验品系中发现有合丰27、29、32、34号及绥86-5345这5个品种(系)上菌株的毒力频率低,说明它们的抗病性能好.同时在这5个品种、品系中分析了2个以上品种的联合抗病性,为培育抗病品种和品种的合理搭配提供了科学依据.
The interaction between 70 varieties, lines and germplasms and 30 isolates of Cercoporasojina from in Heilongjiang province were studied. The result shown that resistant, susceptible andintermediate cultivars, lines and germplasms were identified. Among cullivars Hefeng 27,Hefeng 29, Hefeng 32, Hefeng 34. Sui 86-5345 were resistant becouse theirinfected SCN iso-lates were with lower virulence frequency. Meanwhile, resistance association of 2 cultivars hadbeen found, which provided more scientific informations for breeding broad-spectrum disease re-sistant cultivars.
