白背飞虱是水稻区的重要害虫之一,抗性品种是综合防治病虫措施中的重要内容。抗性鉴定办法,是选育抗性品种的基础,历年找们采用国际水稻研究所试验计划提出水稻抗飞虱的鉴定办法从1975年起我们以种群数量、分布、活动等特征作为抗性鉴定指标,缩短了鉴定周期,对养虫、采虫进行了研究,提出了简化、迅速、准确的办法,可大大加快鉴定工作的进程。现将部分材料整理如下。
White-backed planthopper is one of the important pests in rice area, and resistant varieties are an important part of the integrated pest control measures. Resistance identification method is the basis of breeding resistant varieties, over the years to find people using the International Rice Research Institute proposed rice identification program of resistance to planthopper since 1975, we population, distribution, activity and other characteristics as a resistance identification Indicators, shorten the identification cycle, carried on the study of feeding insects, mining insects, put forward a simplified, rapid and accurate approach can greatly speed up the identification process. Now part of the material sorted as follows.
