Assessing the Potential of Maize Genotypes for Provitamin-A Breeding Programs: Variations in Carotenoid Components

Abstract

Selly Msungu

Maize, also known as corn, is one of the most important cereal crops in the world, providing food, feed and industrial raw materials to millions of people. It is widely grown in many countries due to its adaptability to different environments and its high nutritional value. Maize is an important source of carbohydrates, protein and vitamins, especially provitamin A carotenoids. Maize genotypes are the different varieties of maize that have been developed through breeding programs. These genotypes have unique traits that make them suitable for specific environments or purposes. They vary in their yield potential, disease resistance, grain quality and nutritional value. Maize genotypes can be classified into three main categories: landraces, commercial or elite varieties and inbred lines.
