1982年,我们承担了南方稻区参试品种对褐稻虱的抗性鉴定工作,现将鉴定结果整理如下。(一)材料与方法1.鉴定材料:供鉴品种(系)共43个,由南方稻区各组区试的负责联系单位提供。我们按鉴定需要,对供测品种统一编号。为便于抗、感比较,用台中一号(TNI)和摩德哥(Mudgo)作为感虫和抗虫的对照。2.鉴定方法:鉴定的虫源系经鉴定为生物Ⅰ型的温室越冬饲养褐稻虱。将龄期一致的褐稻虱若虫,饲养在盆栽圆秆或孕穗期的稻株上,用圆筒型40目尼龙纱罩避虫。当大量若虫羽化时,接于事先准备
In 1982, we undertook the appraisal of resistance to brown planthopper in rice varieties tested in southern China. Now, the appraisal results are summarized as follows. (I) Materials and Methods 1. Identification Materials: There are altogether 43 varieties (lines) for reference, provided by the in-charge contact units of each group test in southern rice area. According to the identification needs, we provide the unified serial number for the tested species. For ease of comparison, TNI and Mudgo were used as controls for susceptibility to insects and insects. Identification methods: Identification of the origin of the line identified as biological type I greenhouse winter feeding brown planthopper. The same age brown planthopper nymphs were housed in potted round bales or booting rice plants, with a cylindrical 40 mesh nylon yarn insects. When a large number of nymphs emerge, take the preparation in advance
