  1. Data represent the average carotenoid content (±SEM) of grains from five individual ears per line. Different letters indicate significant differences (P = 0.05) in carotenoid pigment content were determined by Tukey’s HSD test. Values in parentheses represent the percentages of each carotenoid composition relative to the total content. ND = not detected.
