Genetic Analysis of Variation for Carotenoids and Tocopherols in Maize
Carotenoids and tocopherols are two classes of compounds present in maize (Zea mays L.) which may add value to the grain. Both the carotenoids and tocopherols are fat soluble antioxidant vitamins. The vitamin and antioxidant properties of the carotenoids and tocopherols provide health and economic …
