  1. The significance (p value) of the data between somatic and premeiotic cells at the same level of chromosome interaction within the same wheat line was confirmed by Student’s t test. The robustness of the data was indicated by the X2. Data with the same letter within a column represent no significantly differences (when p < 0.05) among both wheat addition lines at the same level of chromosome interaction.
