摘要
本研究对本省目前推广的47个主要稻种进行了二化螟 Chilo suppressalis(Walker)抗性测定,发现中抗品种2个,耐虫品种22个。粳稻较籼稻更抗二化螟,因而,籼、粳稻的防治指标应有所区别。
The resistances of 47 rice varieties extending in this province re-cently to striped stem borer(SSB) Chilo suppressalis(Walker) weretested.Of them,2 varieties were moderately resistant and 22 were tol-erant to SSB.Generally,the japonica rice was more resistant to SSBthan indica rice,so the action thresholds of the two rice groupsshould be differentiated,The resistant mechanism was also discussed.
