* Transformation event that showed significant differences in plant height, days to tasseling/silking, ear length and kernel weight when compared to its null and the B104 line at p < 0.05. The different letters represent lines that are significantly different from the B104 line at p < 0.05. ** Standard deviation values for each phenotypic trait.
