All of the data represent the mean ± SE. A and B indicate differences detected using Duncan's test at P ≤ 0.01. a and b indicate differences detected using Duncan's test at P ≤ 0.05 (starting from a, b is significantly different from a). KL, kernel length; KW, kernel weight; TKW, thousand kernel weight.
