| Abstract |
Purple corn color is expected to substitute for artificial colorants in commercial use
and provide health benefits while combating corn waste. The question of how to
maximize the genetic gain and anthocyanin level of purple waxy corn in practical
breeding arises. We investigated the mode of gene action on anthocyanin yield,
phenolic yield (PY), and antioxidant activity. Also, we selected promising lines with
advanced anthocyanin in whole ear components on the basis of general combining
ability. Seven waxy corn genotypes were subjected to hybrid formation by following
the North Carolina II mating design, and their F1progenies together with their
parents and hybrid checks were laid out in randomized complete block design with
three replications in two growing seasons during 2018–2019. The anthocyanin and
PY of the tested genotypes were quantified, and their antioxidant activity was
assayed through the 2,2-diphenyl-1-picrylhydrazyl and trolox equivalent antioxidant
capacity methods. This study revealed an overwhelming dominance genetic effect,
great reciprocal cross effects, and a low heritability for targeted traits in corn husks
and cobs. The promising lines, namely NSX/DKA/PF for corn husk, PF/AB and
S6248/TB/KND//PF for corn cob, and PF/AB and TB/KND//PF for corn kernel, were
identified. Further strategies and implications in practical breeding are discussed in
this paper.
