Genotypic Variation and Genetic Control of Phenolic Compounds and Antioxidant Activity in Shanlan Upland Rice Landrace.

ABSTRACT: Shanlan rice, a unique drought-resistant rice germplasm resource in Hainan Province, China, holds significant potential for rice genetic improvement and breeding innovation. However, its genetic diversity and significance in rice breeding remain inadequately explored. This study conducted a comprehensive analysis of phenolic acid profiles and antioxidant properties in the brown rice of 84 Shanlan rice accessions. It was revealed that colored Shanlan rice accessions exhibited significantly higher total phenolic content (249.00-2408.33 mg gallic acid equivalents per 100 g of rice flour (mg GAE/100 g)) and antioxidant capacity (DPPH: 680.39-809.63 micromoles of Trolox equivalent per 100 g (μmol TE/100 g); ABTS: 529.93-1917.77 μmol TE/100 g) compared to white-grained varieties.
