The anthocyanin and phenolic yields and antioxidant activity of seven waxy corn genotypes, their F₁ progenies, and hybrid checks grown during two growing seasons in 2018–2019 were assessed. The mode of gene action on the traits of interest was investigated, and promising lines with high anthocyanin in whole-ear components were identified. An overwhelming dominance genetic effect, high reciprocal cross effects, and low heritability for targeted traits in corn husks and cobs were revealed. Promising lines, namely NSX/DKA/PF for corn husk anthocyanin content, PF/AB and S6248/TB/KND//PF for corn cob anthocyanin content, and PF/AB and TB/KND//PF for corn kernel anthocyanin content, were identified.
