Abstract excerpt

Antheraxanthin (ANT) is an important xanthophyll carotenoid in maize, but its genetic basis in maize kernels remains poorly understood. Here, we investigated the genetic architecture of ANT content using a teosinte-maize BC2F5 population evaluated across multiple environments. ANT showed abundant phenotypic variation and high broad-sense heritability (H2 = 0.86), indicating strong genetic control. A total of 11...
