Screening method for selenium-enriched rice variety

The invention belongs to the technical field of screening of agricultural germplasm resources, and particularly relates to a screening method for a selenium-enriched rice variety. According to the method, preliminary screening is performed at first through indoor cultivation, so that the blindness of the subsequent field screening test is reduced; South Henan black glutinous rice is used as a contrast material, so that the screening process is simple and feasible. In the indoor screening process, a selenium-enriched culture medium is used to provide a uniform and stable selenium source for rice seedlings; the accuracy of variety screening can be substantially improved; seeds are started to be cultivated in the initial stage of germination and growth; nutrition is mainly supplied by the seeds to the seedlings; the culture medium is relatively easy to prepare, and the screening method is easy to apply. 本发明属于农业种质资源筛选技术领域，具体涉及种富硒水稻品种的筛选方法。该方法先通过室内培养进行初筛，降低了后续田间筛选试验的盲目性；以豫南黑籼糯作为对照材料，使得筛选过程简单易行。室内筛选过程中使用含硒培养基，为水稻苗提
