• Selenium (Se) supplementation through plant-based foods is easy to implement and effective; therefore, it is important to explore the Se-enrichment ability of staple grains and analyze their quality. The purpose of this study was to investigate the effects of foliar application of Se on the quality, Se-enriched capacity, organic Se composition and content of rice under field cultivation. The results showed that exogenous Se application at 80 mg L−1 contributed the most to the yield, and eight elements differed accordingly to the application of Se, promoted the accumulation of Se-containing organic matter in rice grain. This indicates that rational foliar application of Se can effectively improve the quality of rice grains. Moreover, selenomethionine (SeMet), selenocysteine (SeCys2), and Se-methylselenocysteine (Se-MeSeCys) are important components of Se-enriched in hydrolyzed proteins in grains. Based on these results, foliar spraying of Se is a suitable method to supplement rice with additional Se and can improve the yield and quality of rice grains, particularly the quality of organic Se and Se-containing amino acids. •Foliar application of selenium to rice significantly increases its total selenium content.•Mg, P, S, Fe, and Zn content increased with increasing Se concentration.•Se application promoted the accumulation of organic matter and the content of organic matter containing Se in rice.•Se-Met, Se-Cys and Se-MeSeCys were detected in protein hydrolysates.
