Carotenoid composition in wheat grains from transgenic and control lines in T₃ generation. Average of each carotenoid species are determined from five individual plants ears per line. 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. ND = not detected.
