d Means ± Standard deviation. Mean values followed by different superscript letters in the same column are significantly different at p < 0.05 (LSD). Hunter values: L = black (0) to white (100); a = red (+) to green (-); b = yellow (−) to blue (+). MI = milling index; TKW = thousand kernel weight; HLM = hectolitre mass; PVAH = provitamin A hybrid; RWM = representative white maize. λ These parameters were measured on a dry matter basis.
