Values marked by different letters indicate significant differences by Duncan test (P < 0.05). r2 represents the correlation coefficient between either AFLP or MSAP marker matrices and each alkaloid across all cultivated populations from the dbRDA. P stands for significance test of correlation which values are indicted as: **P < 0.01; ***P < 0.001.
