Screening method of rice variety resource selenium enrichment performance

The invention relates to a screening method of rice variety resource selenium enrichment performance and belongs to the technical field of rice genetic improvement breeding design. The method is characterized by including the steps of firstly, selecting to-be-identified field parcels; secondly, planting to-be-identified rice varieties; thirdly, harvesting the planted to-be-identified rice varieties; fourthly, detecting the selenium contents of the harvested to-be-identified rice varieties; fifthly, analyzing and comparing the selenium contents of the to-be-identified rice varieties in the field parcels, and calculating the average values, the maximum values and the minimum values; comparing the average values, the maximum values and the minimum values of the selenium contents to obtain a conclusion. By the screening method, rice variety selenium absorbing capability difference can be screened and identified, fertilizer applying blindness is reduced, environmental pollution is relieved, and economic benefits are increased.
