Linear regression between antioxidant properties in wild clones, cultivars, and hybrids. (a) Total antioxidant activity by DPPH (mg GAE/g fl) and total phenolic content (mg GAE/g fl). (b) Total antioxidant activity by DPPH (mg GAE/g fl) and total flavonoid content (mg CE/g fl). (c) Total phenolic content (mg GAE/g fl) and total flavonoid content (mg CE/g fl).
