Biochemical and Yield Component of Hybrid Chili (Capsicum annuum L.) Resulting from Full Diallel Crosses

Chili (Capsicum annuum), economically important, is one of the world's most popular horticultural plants. Functional biochemical components, such as polyphenol content, antioxidants, and a-glucosidase inhibitory properties, are found in chili. The purpose of this study was to evaluate a chili hybrid that resulted through full diallel crosses for its yield components, total phenolic (TPC) and flavonoid content (TFC), antioxidants, and alpha-glucosidase inhibitory (AGI) activities. The Folin-Ciocalteu and AlCl3-colorimetric assays were, respectively, used for TPC and TFC analyses. Using 2,2-diphenyl-1-picrylhydrazy (DPPH) and ferric reducing antioxidant power assay (FRAP) techniques, the antioxidant activity of a sample was determined. The bioassay of a-glucosidase inhibition was used to evaluate the antidiabetic activity of the sample. The twenty-five genotypes (hybrid and parent) have diverse yield components and biochemical contents. The highest fruit weight per plant was found in IPB074005 (1008.85 g). IPB114367 showed a high AGI (80.25%), antioxidant FRAP (43.42 mu mol TE g(-1) DW), TFC (3.97 mg QE g(-1) DW), and TPC (37.51 mg GAE g(-1) DW). These findings suggested that hybrid plants that suppress alpha-glycosidase and oxidative stress may prevent diabetes and its complications. This vital information could help design replacement drugs and diabetes diets.
