摘要
建立科学的水稻抗虫鉴定体系,是开展水稻抗虫性研究的关键环节之一。描述了稻飞虱、稻纵卷叶螟和二化螟的发生、发展特点,在此基础上详细分析和讨论了3种害虫抗虫鉴定体系中的几个关键环节,对3种害虫的抗虫资源做了统计,并提出了室内和田间抗性评价流程及评价标准,以进一步完善水稻抗虫性鉴定体系。
The establishment of scientific identification system for rice resistance to insect pests is one of the key links in the research of rice varieties in pest insect resistance.The occurrence and development characteristics of rice planthopper,Cnaphalocrocis Medinalis and Chilo suppressalis were described.On this basis,several key links in the identification system for rice varieties in resistance to the three insect pests were analyzed in detail.Ten rice varieties in resistance to the three insect pests were calculated statistically.The indoor and field resistance evaluation process and evaluation criteria were proposed so as to further improve the identification system for rice varieties in insect pest resistance.
