A field experiment was conducted during winter of 2022-2023 in one of the fields at the Shumali region in Babylon Governorate, within latitude of 32.32˚ north and 44.92˚ east. The study planned to evaluate oxidative activities and flavonoid content to four varieties of oats (Shifaa, Oat11, Algouda, and Carlup). The experiment was carried out according to randomized complete block design with three replications, All data were collected and analyzed according to analysis of variance table. The means were tested according to the least significant difference test at 0.05 probability. The results showed significant superiority of the Algouda variety in plant height (127 cm), flag leaf area (27 cm2), and capacity of total antioxidant (83.8 mg g-1 dry weight). Total flavonoids (163.8 mg kg-1 dry weight), free radicals inhibition efficacy in grains (72.58%), and the grain content of some Flavonoid compounds. Shifaa variety was significantly superior in the number of tillers (478.1 tillers m-2), number of spikes (457.4 spikes m-2), weight of thousand grains( 36.97 g), and the grains yield (7.15 tons ha-1).
