In order to ascertain the influence of soil selenium content on peanut selenium content, a total of 19 peanut varieties were used as materials. Three discrete treatments of soil selenium content were employed, comprising 0.42 mg/kg (treatment A), 0.73 mg/kg (treatment B) and 1.08 mg/kg (treatment C). The impact of varying soil selenium levels on the selenium content and selenium enrichment coefficient of peanut seed kernels was evaluated. A field trial was conducted using a randomised block design. The results demonstrated considerable variability in the selenium content and selenium enrichment coefficients of the seed kernels of the different varieties in the different treatments, with ranges of 0.102-0.306 mg/kg and 11.32%-40.16%, respectively. The seed kernel selenium content was found to be consistent with the specified limit value for selenium content in selenium-enriched peanuts (0.05-0.5 mg/kg) as outlined in the regional standard of Guangxi (DB45T 1061-2014). The seed kernel selenium content of peanuts was found to be higher under treatment C, while the selenium enrichment coefficient of peanuts was higher under treatment A. Among the participating varieties in diverse treatments, the seed kernel selenium content and selenium enrichment factor of 'Guihuahei 1' were found to be the highest. 'Guihuahei 1' shows efficient and stable selenium enrichment ability in soils with different selenium contents, and is an excellent variety for producing natural selenium-rich peanuts.
