我国稻种资源丰富,存在着许多特殊性状的品种,收集和鉴定稻种资源的有关特征和特性,是培育新品种的亲本源泉。1986—1987年就江西省稻种资源进行抗白背飞虱的鉴定,筛选出一批抗白背飞虱的品种,再作进一步的研究,可为育种提供一批亲本材料。1.材料由江西省农科院水稻研究所提供江西地方稻品种764份。2、方法采用国际育苗盆标准苗期集团筛选方法。用TN_1作感虫对照品种,N_(22)作抗虫对照品种。
Our country rice variety is rich in resources, there are many varieties of special traits, collection and identification of the relevant characteristics and characteristics of rice resources, is to cultivate new varieties of parental source. From 1986 to 1987, the identification of the whitebacked planthopper, Sogatella furcifera, in Jiangxi Province was carried out. A number of varieties resistant to Sogatella furcifera were screened out for further study, which could provide a number of parents for breeding. 1. Materials Provided by the Institute of Rice Research, Jiangxi Academy of Agricultural Sciences, Jiangxi Province, 764 local varieties of rice. 2, the method adopts the international seedling pot standard seedling group screening method. TN_1 was used as the control of the susceptible insects and N_ (22) as the insect-resistant control.
