The objective of this study was to evaluate the physical and chemical properties such as plant height, length of panicles, number of effective tillers, total number of grains, number of unfilled and filled grains, weight of 1000 grains, biological and economic yield, harvest index, chlorophyll index, growth period, total phenol (TP), and total antioxidant capacity based on 2,2-diphenyl-1-picrylhydrazyl (DPPH) in 30 genotypes of elite rice grown in Iran. The highest 1000-grain weight was observed in genotype IR56 (G30) with 27.15 g; the highest biological yield was observed in Neda (G28) genotype (24.92 t/ha) that was at the same statistical level with national genotype (G25) (24.19 t/ha). Keshvari genotype has the highest grain yield (7.64 ton * hec). The highest amount of chlorophyll index was observed in genotype line 101 (G9) with 45.75%. In addition, the range of antioxidant capacity based on DPPH was 9.033–19.067% and genotype 13 (Bijar) had the highest antioxidant capacity. The highest TP content was 1.137 mg gallic acid (GAE) per g. According to the correlation, (0.555) had a positive and significant correlation with the antioxidant capacity based on DPPH. Also based on cluster analysis, the 30 genotypes were located in 5 main clusters. The present research reveals the potential of rice (Oryza sativa L.) genotypes studied for the improvement of nutritional value through germplasm enhancement programs.

这项研究的目的是评估物理和化学特性，例如植物高度，穗长，有效分till数，谷物总数，未填充和已填充谷物的数量，1000粒重，生物学和经济产量，收成伊朗种植的30个基因型水稻的2,2-二苯基-1-吡啶并肼基（DPPH）指数，叶绿素指数，生育期，总酚（TP）和总抗氧化能力。在基因型IR56（G30）中观察到最高的1000粒重，为27.15 g；Neda（G28）基因型（24.92 t / ha）的生物产量最高，与国家基因型（G25）（24.19 t / ha）的统计水平相同。Keshvari基因型具有最高的谷物产量（7.64吨* hec）。在基因型品系101（G9）中观察到叶绿素指数最高，为45.75％。另外，基于DPPH的抗氧化能力范围为9.033-19.067％，基因型13（Bijar）具有最高的抗氧化能力。最高TP含量为每克1.137毫克没食子酸（GAE）。根据相关性，（0.555）与基于DPPH的抗氧化能力具有正相关和显着相关。同样基于聚类分析，这30个基因型位于5个主要聚类中。本研究揭示了水稻的潜力（这30个基因型位于5个主要簇中。本研究揭示了水稻的潜力（这30个基因型位于5个主要簇中。本研究揭示了水稻的潜力（通过种质增强计划研究了水稻的基因型以提高营养价值。
